Looks like I made one more mistake! The Transcend card reader I own is the RDF8 reader but it has since been replaced with the RDF9 reader (that looks identical) that is made for UHS-II cards (two rows of pins). Keep in mind that the Sandisk card is UHS-1 and it still performed better in the ProGrade reader so I'm not expecting the new Transcend card reader to perform as well, but it will probably be somewhat better than my tests with the Prograde card + Transcend reader. I'm going to buy this new card reader and then do a new video just about that.
Props on redoing the video. Of course in UHS 2 vs USH 1, UHS2 will perform better. It would be interesting if you guys could compare a Sandisk UHS2 card and a Prograde UHS2 card and take a look at the differences.
I hate to say there bud, but you are mixing up the USB 3.1 Gen 2 and UHS-II. These are completely different and unrelated standards. People don't help, talking about USB 3.0 as that standard no longer exists and was swallowed up into USB 3.1 Gen 1. The issues stated were more with regards to testing methodologies, there are some great standards and methodologies used in the tech review community on UA-cam and it would have made more sense to look to some of those and how they go about a consistent test, especially with regards to potential caching.
+1 Would like to see Prograde UHS-II vs SanDisk UHS-II write speed tests using the Prograde card reader/writer. Tests could include standard windows file copy of (~50GB+) large video file(s) and a second test with (~50GB) smaller raw files, 3 tests of each file type back to back to each card. Then test both cards using a storage perf tool like HD Tune and/or ATTO. Primarily interested in the sub par v30 minimum write spec on the Sandisk UHS2 vs the Prograde (or Sony) v90 spec. For any given size UHS2 card, the SanDisk models seem overpriced compared to the Prograde or Sony given the SanDisk's v30 spec. (For the record, I own a SanDisk 128GB UHS-II card and feel it's over priced if the most it can reliably perform is v30 on writes.)
Well, there can be differences between theoretical caps and realistic speeds, and will sometimes be reflected even when you don't reach the peak value.
I rarely watch these guys and this just came up on autoplay but have to say, if they are so salty about their audience, maybe they should consider a new career path...
@@mstrainjr aye that's my point, switch comments off if don't like em, but wait, that's where the money lies, deal with it or find a new audience. Pretty sure they were quick to pull Northrup when believing shit dun wrong...
It wouldn't matter anyway since the USB 3.0(aka USB 3.1 gen1) speed of 5Gb/s is equal to 625MB/s, so 2.5 times the max speed of the faster card (250MB/s). Also the USB C port on the back of his PC may actually be USB 3.2 which supports up to 20Gb/s (2.5GB/s, 2500MB/s).
USB 3 has 625MB/s bandwidth. Usually you can get about 465MB/s of real world here. Only UHS III cards (never released) or the future SD Express can use gen 2 bandwidth (1250MB/S) as the UHS 3 uses 624MB/s and SDExpress 985MB/s (maybe even gen 2x2 is needed)
Hang on... at 2:50 - you're talking about transferring data from the card to the computer, but the screen is showing "Copying from desktop to card"... Isn't that contradictory..? So at 4:47 the top row should say writing speed, and lower row reading speed, not the other way around. Is that just me or am I missing something here?
I have exactly the transcend reader you show on B&H and it does over 200 MB/s in both directions. The thing is, the Transcend reader on your PC isn't the one on your B&H Page! You have the non UHS-II Reader, that one is significantly slower. you can see it because yours is missing a UHS-II label. This Video is pointless if you didn't know what you are testing....
You have been doing this for awhile so you know to ignore the critics and haters. You got this! Thanks for the info. I think I will stay with the old, cheap reader and chips. My workflow being what it is.
You got confused where 80% of the population gets confused. Nice work in explaining the confusion and going through the tests again. Great video, very useful info. Cheers man
One major thing you are forgetting and that is the device's (e.g. your camera) read/write performance. It's pointless using a UHS-II card in a device that maxes out at UHS-I speeds. All UHS-I compliant camera's can use UHS-II cards and visa versa, but the speed limits will be dictated by the card reader/writer interface in the device. To add to the issue is that not all read/write devices comply to the maximum of the standard and so the device you are using may not fully utilise even a UHS-I card. In these scenarios the only advantage is in the use of an external device to transfer the data and that would only become a real advantage if the amount of data to be transferred is significant, like from 16GB or more, so that instead of 5 minutes you are looking at two minutes. 5 minutes is the time it takes to make a coffee which may put this all in perspective. Even the most basic SD card reader will be able to read and write to all the different cards, but at a significantly lower rate. Some older devices especially budget or entry level devices, don't include a top of the line interface for a given standard and thus will be subject to suppressed read write speeds in the device. The main advantage of using a card capable of utilising the camera's internal speeds optimally is the time it takes to clear the devices buffers. Once that has been obtained then faster becomes pointless in the field. One good test is to set up continuous raw shooting on the camera, and let it rip so that it slows down to buffer clearance and see how many FPS it can maintain in that state, cards which maximise the bandwidth of the internal reader/writer will be able to maintain a faster FPS than if the card is limiting the bandwidth. If your camera can handle UHS-II natively, then it's silly buying UHS-I cards for anything other than as backup cards if you need the increased speeds internally, if you don't then it's pointless paying more for speeds you will never use. Which is the better choice is determined by the use case scenario. If you never hit buffer slowdowns continuous shooting or don't use high bitrate video, then you may never need the faster speeds. A specific test case I just did is the D5300 with an Extreme pro and an Ultra card, once I hit the buffer being filled (about 5-6 shots) the Extreme pro was able to maintain at least one shot every second while the Ultra card took roughly 3 seconds between shots. Given that the 5300 is UHS-I compliant (i.e. faster than 25MB/s of the standard SD interface) and is reported to be able to attain at least 50MB/s continuous write (slower than a good card reader) using timed buffer testing which is slower than the max write speeds of 90MB/s of the card and the 104 of the standard, it can be said that the 5300 only has an average read/write interface in the technology it is using, but is roughly the same as a low priced USB 3.0 UHS-1 reader (the transend is actually a good UHS-1 reader writer, just not an excellent one) and just enough to saturate the USB 2.0 interface on the camera. The extreme pro cards I have using the transend USB 3 UHS-I reader writer I have will read at about 90 MB/s and write at around 80MB/s which is roughly 10% below the maximum ratings of the card. Other budget reader writers I have used can barely get half that on writes (often less than 30MB/s) and aren't much better at reading.
so here is the thing, what does your camera like best? transferring photos isn't what bite my shorts it is waiting for the buffer to clear when i'm shooting. some of the newer cards are not any faster than the older cards. they can even be slower if the camera can't talk to the card well. so get the best card for your camera and have fun.
What cracks me up... being in the computer field area, many of us know this and know how to read memory cards, however it is a BIG MISS even for us to translate what we now think of as common knowledge to another industry that must rely on memory cards. So glad you cleared it up for THIS industry and in a very authentic way using a 'real world' test. Great Job! Love the fact that you also CALL out the haters :) Even as my marketing coach has said... any form of advertising is STILL advertising and in this day in age, controversial comments can do a lot to build awareness and you gain a lot of CRED when you show growth in front of the masses at that point. Great job again!
A few questions: 1. How is the performance with the onboard card readers that many Windows laptops have? 2. Write speed in camera is what really matters to me. There are times when I am shooting something in motion, and the camera can slow down because stills are backed up as the camera tries to write to the card. How does in-camera performance look? I find that the faster cards are helpful if I am doing burst shooting -- the kind of shooting you might do with wildlife or sports. But I'm still not sure the cost difference is worth it. (For example, the fastest Sony SD 128 Gb card is over $220 !) 3. How does performance go if you attached the memory card reader to a USB hub? (I have a hub that attaches to my computer via USB 3.1 C.)
Nice job on the slightly revised video. It's interesting that the port change allowed for max transfer on the two simultaneous cards. I had no idea on the multiple versions of USB either.
ok, so the usb debate at 7:00 it wont make any difference because i doubt the card reader will even max out the slower usb 3 speed so plugging it into a faster port will not make it read faster.
Serial printer cable? Last time I used a printer before the USB came it, it had a parallel centronics connection. Serial printers... I've never seen one with an RS-232 connection, even though I've seen some software offering support.
The reason the write test was faster to transfer using the better card reader (as supposed to the Transcend) with the Sandisk is because of caching. The computer or memory card will cache the data so a recently accessed item will transfer quicker. A better test would have been to either reformat the card, or clear the cache on the computer.
Transcend has 4 card readers that look like the reader you used. Only 1 (the RDF9) can read UHS II cards at full speed. Were you using the RDF9? Giving a link is not the same thing. It would explain why the Transcend was slower with the Pro Grade UHS II card (it was being read at UHS I speeds). I have extensively tested USB3 card readers (less so USB3.1 readers), they are all very close in performance.
I commented on the first video and came to your defense. haha I fully understood the methodology of your test and it appears others didn't. It's UA-cam and some people are only on here because they can't read - so we have to remember that and hold their hand sometimes. Glad you uploaded this video again. P.S. Please make another comical video like your hipster Nikon DF review...possibly the greatest video on UA-cam.
You wont believe,by how much.... I was lucky to get very fast reader with memory card. Also alway use direct usb readers without cable IT DOES MATTER!!!
Excellent video. I often wondered what diff it made for the device you were using to read/write to your memory card, you answered my question exactly. But I have a question - what if your camera only uses film? ha ha ha........oh oh oh, I saw some really nice cameras that used glass negatives - ha ha ha....oh different subject, different topic on antique cameras. cutting age 1800's style. If you shop around you can find used sdxc cards for a lot less than new ones !
Didn’t see the first review but this one is really helpful. I, like you incorrectly assumed “a card reader is a card reader”...huhh. Who knew? Most importantly, I had no idea what the V number meant and so that information is gold. Takes a lot of the mystery out of shopping for SD cards. Thanks for taking the time to not only review once, but twice!
Having worked in a high-end camera store for over 6 years, I can say one of the most frustrating things to sell is memory cards. We dealt mainly in C.Fast and SDXC cards, and about 70% of the time the customer would choose the wrong card. Keep in mind, our customer base was primarily small-to-medium business owners, often with more money than sense, having had their finger off the pulse for many years, focusing on building their business instead of actually shooting and keeping up to speed. Trying to carefully explain to this kind of person that they're wrong, the number on the box doesn't matter and they'll have to spend about 4x that price to suit their needs was a perpetual nightmare. I'd say about half of those customers thought we were trying to finesse them into buying a higher priced item which they didn't really need, so they would buy 30 or so of the cheaper cards only to come back in a couple of days with a head full of steam, ranting and raving about false advertising, accusing us of selling counterfeit cards, demanding refunds, etc etc.
Hi, I tested the Prograde Dual SD card reader with provided USB C cable on Macbook Pro 13" 2019 2.8ghz with Sony SFG 64GB UHSII cards rated at 300m/b read and write. I copied 13.53gb of RAW files from one card to the laptop and got a transfer rate of 251 megabytes per second. (13.53gb in 53.74 seconds). I then copied combined 12.72 gb of data from two cards and got a transfer rate of 318.63 mb/s from two cards. Any idea why the data transfer rate was not higher? This is not even close to saturating the USB C cable. I have been using the StarTech 2SD4FCRU3 Dual-Slot SD Card Reader/Writer - USB 3.0 - SD 4.0, UHS II for a while and this does not seem to be worth twice the price due to the lack of boost. Perhaps it is time for a Prograde vs. StarTech, The Real Truth video. At least I got a fridge magnet with the Prograde.
jebis03 Totally agree. Gawd, the current backwards snap-back style is just awful and so many guys are doing it. Just wear a fitted cap backwards. Frickin' patch of shiny forehead, sometimes with a few hairs sticking out on some of these guys..ridiculous. They look like hammered dooods from the late '70s at a Lynyrd Skynyrd concert. "Free Bird, man!"
Lee, I have the same Transcend reader you have, if you look closely at yours, it says "USB 3.0", but the current model Amazon sells says "USB 3.1/3.0". That means the current model was silently upgraded, but the specs on Amazon match USB 3.1 performance.
@@LesChroniquesDeGeorge Every product made in China by underpaid workers and sold in the US and Europe for a stratospheric price is a scam. The most obvious example is smartphones, SD cards, anything sold by Apple and other multibillion dollar companies. Nowadays we have Chinese companies making the exact same product and selling it for a fraction of the cost. IPhone and Xiaomi, Metabones and Viltrox and so on...
Psaikodelik I completely agree with you! I bought my Nikon D850 which I paid 3800€ for it! And it’s made in Thailand! I’m sure it only cost 200-300$ to make it! Not to mention the Sony SD cards and the XQD cards... I got a new MacBook Pro which I can’t even edit 4K video because is too slow I paid 1600€ anyway! As a photographer you need all this stuff!
@@LesChroniquesDeGeorge When you look at it in terms of cost to make it do you think that represents the totality of the cost? Is cost only raw materials and labor? Cost is much more complex than that. Research is a massive cost that needs to be offset. They spend millions of dollars for years in product development. You did not include that in the cost. Marketing that cost. When they sell it to B&H of whoever that was not 3800. When the camera breaks that is a cost to service the warranty, on and on. Why do people look at only cost to manufacture? With the Macs they just ripping you off, no idea on EARTH why you would need them to edit a photo. you just complained about cost and invested in the largest con on Earth "You need a mac"con.
AHS Society I agree with you 100% it goes the same way when we as photographers charge a lot of money for a shot! Is not just the click to take a photo but years of experience and material costs... I’m not complaining, I understand everything it goes into the process of manufacturing and research ! As why I chose Mac over a PC trust me! I can’t deal with windows anymore ! I did it for years but the instability of the system let me down many times and a lot of lost work in due process ! It’s not a must but is a choice
I have 2 Sandisk Extreme U3 uhs1 32GB SD Cards, I use Ugreen $5 usb 3 Card Reader into My Anker USB 3 Hub $12 into USB 3 Port in the Back of my PC. I get no less than 80-85MBPS when dumping data from SD Card onto 7200 rpm WD 1TB HDD. Wondering how you're getting slower speeds with Extreme Pro 95Mbps cards?
because he is an idiot! he is promoting the prograde obviously! i'm not saying he do it intentionally but in the end everybody is going to think sandisk and transcend are garbage and the prograde is so good!
Did you ensure that both reader devices are using the same driver? If not that is where at least some of the difference could be coming frorm. There needs to be some explanation for why the cheaper reader went form fast, to slow, to fast again... all during the same test.
I bought a Sony Tough Sd card which claims to be faster than that prograde one - but then it might just be marketing spiel as I don't understand the numbers - it's claimed to be stronger (harder to actually snap/break) than others and water/dustproof too. Have you tried them? Mine is only 32gb and I use the slower cards in the second slot for jpegs. Not sure if it it's any speedier in camera as I only do single shot stuff (though a lot of) but it does seem quicker on download to disc.
You also should've used a RAM disk instead of your system SSD. This eliminates some variable factors such as a Windows update downloading in the background slowing down your drive.
You also need a Backup of your family photos because if that HDD gets damaged or fails and you cant get data recovery then you would lose ALL of your Photos FOREVER!!!! that's a no brainer!
I just tested a 95mb/s card and tried to write 400Mb 10Bit DCI 4k video to it... As long as I didn't use all-intra compression, it went ok. But as soon as I tried the all-intra... No could do. So I had to spend 3 times the price for a properly fast SD card. How quickly it unloads, have been less of an issue. In camera performance is the main concern.
@@lorenzoamato953 There are plenty go better options out there. If you really need a magnet you could always glue a smaller and less powerful one on the bottom of any old card reader or better yet use velcro. I have been using card readers since 2001 and have never had the need for a magnet on them.
PJ Smith the magnet will probably be a old ferrite magnet and is not strong enough to effect the cards, - even a small neodymium one - is doubtful to effect it)
@@lasarith2 I'm sure your right and I was half joking, but also honestly would not buy one of these. I guess I just don't like the idea of it, but I will admit I'm no expert on magnets.
question, does your older cheap reader even have the ability to utilize the extra connectors on that pro grade card? For example if you bought a cheap reader that had the ability to use those extra connectors it might be just as fast as the prograde still....... Can't help the knee-jerk reaction, but this still feels like a commercial to sell a product that was given to you I think for your test to be totally accurate the readers need to have the same capabilities on all accounts one brand name one cheap o.
I don't quite understand the minimum write speed for a card. What exactly does that limit mean? If a camera, or card reader, tries to write at a slower speed it will fail? Why should I be concerned with minimum write speed. (I use a Canon 60D)
I am so glad that you included the information that starts at 10:06. Transfer speeds between the card and computer are fine and interesting, but it's the transfer speed from the camera to the card that is ALL IMPORTANT. If the camera overwhelms the card and stops recording, you'll have diddly-squat to transfer from the card to the computer.
A factor that's important to me, DURABILITY. I wish there's a way to simulate the test on durability. I'm even willing to sacrifice some speed for more durability.
Fstoppers : Thank you for this informative video on memory cards , not everyone is a pro at photography and the equipment necessary to excel in this digital world ! Your video helps teach us what to expect from a memory card in terms of performance , including how well a card reader works with a comparison in real time ……. Between the average car reader the Transcend verses a professional card reader Prograde ! Yes, in the end we all must make decisions on what to use , and then purchase the required equipment whether one is just starting out , or is a bona-fide pro at filming !!!!!
Good video, but I think you neglected to point out one very important criteria - can your camera utilize UHS-II cards? I know that mine cannot. Pretty much any camera over 3 years old (and even a lot of current models) are limited to UHS-I, so getting that faster UHS-II card may not make any difference in how fast you can write to the card in your camera (V60 or V90, for example), although it will certainly give you faster write speeds to your computer.
Only problem I have with this test is that you should have also used some much bigger files of 20gb or so to se if it can sustain speed over a long time, other than that buying better card readers after this^^
...you compared a UHS I to a UHS II no wonder the ProGrade SD is faster in all respects lol. My question is does that matter for Camera's like the 550D or 7D, etc for video?
Question - what would most likely be faster - the SD card reader in your laptop or PC or something like the Prograde plugged into a USB port (assuming fast USB port)? TIA.
Depends. If you're comparing two cards with the same read/write speeds (or very similar) then the more expensive one might be a rip-off, but if you're comparing a card that writes say 200 MB/s versus one that writes 90MB/s but the one that writes 200 MB/s is twice as much, that might be worth it if you do a lot of burst shooting and need the write speeds. Where it wouldn't probably make sense is if the cheaper one wrote 170 and the expensive one wrote 200, as that's not really that much of a difference for twice the price for example. To save money, I've bought a mixture: faster cards for when I'm doing things like wildlife or sports where I'm burst shooting a lot, and slower cards for when I'm doing things like landscape where I don't usually shoot bursts (if at all) and write speed is not critical. Granted this doesn't save a ton, but for larger cards, buy slower cards for when you don't need super fast write speeds can save a fair amount of money (for example, a slower 128GB Sandisk card can be about $30 that writes only 45MB/s let's say, versus about $200 for the faster one that writes 250 MB/s).
Logan Cressler fair comment buddy,, that’s good to know,, just,, my concern was with the complete system,,, contents,,, just magnets man,,, in the right place , yes,, not for me on PC ,,, Great on a fridge door,,🤪🥛🍨🍉🍻
I wonder if a UHS-II card will transfer to a PC faster in the Pro Grade reader than UHS-I even if my Canon Vixia HF G50 camcorder did not write it in UHS-II? P.S. I thought you are supposed to avoid magnets with SD cards. ???
Windows 10 has some known problems with SD and USB large file transfers..... The particular drivers used make a big difference.. Also the OS will cache the files depending on all sorts of different variables leading to skewed results
Its is quite sad that our lives are now consumed by speed , 20 sec approx - 10 secs approx Good Lord $380 for tens secs I think I would just put the kettle on for a cup of tea. There is always going to be improvements but people are losing prospective.... If you are just starting you buy what you need to get the job done, today you would buy the $80 reader , years before the cheaper one still did the job . In ten years why would you change the $80 reader for a $160 reader if it still does the job.... We are all getting to a point where the idea of money growing on trees is being believed. Still if you take a job and get paid $ 500 and then spend it on a Card and a reader with all your gear and expenses for twenty second not quite sure how anyone can justify the logic in that. The company's should be making the improvements ,make the products cheaper in order for people to buy without hesitation instead of just trying to bleed people dry for ten seconds the cost ratio just cannot work... but good to see the comparison.
If you have a 256GB card you are probably going to use a good portion of that (maybe with a 4k video). With the prograde reader you save 12 seconds with just a 1,5GB file, let's say you need to copy 200GB, it's 26 minutes faster, a pretty noticeable improvement, especially if you are a pro...If it's just a hobby, get the cheap one and wait of course :) PS: i'm sure that a mid level reader (30$ maybe) is as fast as the prograde.
Unfortunately we live in the 4k age. To record with my A7iii on 4k, you need a UHS II card. sure you don't have to buy the 256g ones but if your clients want more then 5 seconds of footage you gotta bite the bullet. People aren't buying this card for the copy speed, they're buying it so they can get the max out of their cameras.
JWGFoto I understand but I always build in A time factor at the start a Bit like Scotty from Star Trek tell them four hours when you know it s two .. Iol
Can totally tell you haven't gotten back home at midnight after shooting a wedding and need to transfer 3 memory cards worth of A7riii images... I want to get the images backed up ASAP. The sooner I have them safely backed up in a total of three locations ( 2 card and a HDD) the sooner I'm able to stop being paranoid, the sooner I can edit a couple of sneak peaks but more importantly, the sooner I can slide into bed and cuddle the wife I haven't seen all day. Will happily splash the cash for more time doing other stuff.
I very much enjoy your video's, you are a funny guy, I think a few silly jokes and hop right back into , concise and your well spoken energetic rap .. Bravo ! ( What happened with Puerto Rico ? )
You should have tried to unmount (or safe remove) the cards after the write tests. I have no experience with windows but on linux that will call a sync operation which will require to flush ALL the caches.... and sometimes it takes a lot of time of extra time. What if your expensive reader has a much larger cache and tricks your pc into believing that the transfer is completed while it is actually still writing on the card???
I just put my cheap SD card into my cheap reader and have a coffee , had a nice coffee and images down . Stop all the stress and enjoy your photography. Man who really cares.
Are you sure that your cheap Transcend reader is the same one from the B&H page you showed, the RDF9 version, which has the extra set of pins for faster UHS-II cards, and it's not the RDF8 model that doesn't? Because they look exactly the same, only the older model can't go faster than 80MB/s.
Camera manuals generally caution using the memory card near areas with strong magnetisation, as the data on the memory card may become damaged. I just wonder whether your prograde reader with the magnetic back has any effect on a card?
Hey. Where do you copy from? I hope it was previously copied so that it had it in memory/buffers or it originated from ram disk. Everything else I'm thinking your not timing the time to write but the time to read into buffers vs time to read from buffers. Also if I remember correctly it might be stuff in buffers until you have ejected it. Thus the write might not have been finished even if it says it has. I really would have used linux, turned off buffers and done a dd test and a random access filetrasfer test using the time command. The method you're using is horrible and doesn't give accurate results.
Could you please test how using V30, V60 and V90 cards affect the number of pictures you can take while burst shooting pictures? I own a Sony a6300 and would like to know if I can benefit from upgrading to V60 cards.
why would read speeds randomly drop from one reader to the next with the same medium, and go from a hard throttle point from 60 megs to 15? i'm not familiar with this happening under any circumstances i know of.
Thank you for taking the time to review the tests. Can't speak for anyone else, but my comment on the previous version of the video was not to criticize you, but just to state that these "potential errors" had left me unsure about which combination of cards and readers to buy. Thanks again for clarifying!
Could you repeat the tests, but starting with the expensive reader first? I'm afraid some caching is at play here, so the 2nd test each round had some advantage from the previous operation.
You said "SSD Drive", meaning Solid State Drive Drive. Reupload it again.
Sacha Korban hahaha
I was like , oof...
Reupload it again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Haha
Sacha Korban yeah man get it right. Just like when people say it’s atm. It’s pronounced atm machine
Looks like I made one more mistake! The Transcend card reader I own is the RDF8 reader but it has since been replaced with the RDF9 reader (that looks identical) that is made for UHS-II cards (two rows of pins). Keep in mind that the Sandisk card is UHS-1 and it still performed better in the ProGrade reader so I'm not expecting the new Transcend card reader to perform as well, but it will probably be somewhat better than my tests with the Prograde card + Transcend reader. I'm going to buy this new card reader and then do a new video just about that.
Props on redoing the video. Of course in UHS 2 vs USH 1, UHS2 will perform better. It would be interesting if you guys could compare a Sandisk UHS2 card and a Prograde UHS2 card and take a look at the differences.
I hate to say there bud, but you are mixing up the USB 3.1 Gen 2 and UHS-II. These are completely different and unrelated standards. People don't help, talking about USB 3.0 as that standard no longer exists and was swallowed up into USB 3.1 Gen 1.
The issues stated were more with regards to testing methodologies, there are some great standards and methodologies used in the tech review community on UA-cam and it would have made more sense to look to some of those and how they go about a consistent test, especially with regards to potential caching.
+1 Would like to see Prograde UHS-II vs SanDisk UHS-II write speed tests using the Prograde card reader/writer.

Hahahaha
And you could probably spend $5 on a magnet to glue to the bottom of RDF9 reader and get that same fancy feature of the ProGrade.
I love the complaints about 5gb vs 10gb, when neither device is even hitting 2gb.
Well, there can be differences between theoretical caps and realistic speeds, and will sometimes be reflected even when you don't reach the peak value.
Be careful, you will trigger the snowflakes with your reasoning.

“Who’s the idiot now?? I don’t even know the features of my own computer.”, is it a trick question?
I think it might be a self-deprecating joke...
It wouldn't matter anyway since the USB 3.0(aka USB 3.1 gen1) speed of 5Gb/s is equal to 625MB/s, so 2.5 times the max speed of the faster card (250MB/s). Also the USB C port on the back of his PC may actually be USB 3.2 which supports up to 20Gb/s (2.5GB/s, 2500MB/s).
@@theirishscionyeah I think it was
Fixing your ignorance is commendable, not idiotic.
Found the idiot
@Fstoppers I am getting 160MB/s read (copy) speeds using the affordable $25/$20 proprietary card reader for the Sandisk 170MB/s UHS-1 cards.
I found nothing wrong with the original test. Nice to see you are willing to react and redo it! Cheers!
USB 3 has 625MB/s bandwidth.
Usually you can get about 465MB/s of real world here.
Only UHS III cards (never released) or the future SD Express can use gen 2 bandwidth (1250MB/S)
as the UHS 3 uses 624MB/s and SDExpress 985MB/s (maybe even gen 2x2 is needed)
Good job on the take 2 guys. Enjoyed it the 2nd time as well. :)
Hang on... at 2:50 - you're talking about transferring data from the card to the computer, but the screen is showing "Copying from desktop to card"... Isn't that contradictory..? So at 4:47 the top row should say writing speed, and lower row reading speed, not the other way around. Is that just me or am I missing something here?
I have exactly the transcend reader you show on B&H and it does over 200 MB/s in both directions. The thing is, the Transcend reader on your PC isn't the one on your B&H Page! You have the non UHS-II Reader, that one is significantly slower. you can see it because yours is missing a UHS-II label.
This Video is pointless if you didn't know what you are testing....
Wow so true. Is this guy being serious!!! Made me waste hours of my time!
You have been doing this for awhile so you know to ignore the critics and haters. You got this! Thanks for the info. I think I will stay with the old, cheap reader and chips. My workflow being what it is.
you made a mistake you wore your hat backwards. LOL :)
thanks for sharing great video.
You got confused where 80% of the population gets confused. Nice work in explaining the confusion and going through the tests again. Great video, very useful info. Cheers man
Honestly I have to say. You manage to do reviews without them feeling like reviews. I learned a lot from your test here and keep up the great work.
One major thing you are forgetting and that is the device's (e.g. your camera) read/write performance. It's pointless using a UHS-II card in a device that maxes out at UHS-I speeds. All UHS-I compliant camera's can use UHS-II cards and visa versa, but the speed limits will be dictated by the card reader/writer interface in the device.
To add to the issue is that not all read/write devices comply to the maximum of the standard and so the device you are using may not fully utilise even a UHS-I card. In these scenarios the only advantage is in the use of an external device to transfer the data and that would only become a real advantage if the amount of data to be transferred is significant, like from 16GB or more, so that instead of 5 minutes you are looking at two minutes. 5 minutes is the time it takes to make a coffee which may put this all in perspective.
Even the most basic SD card reader will be able to read and write to all the different cards, but at a significantly lower rate. Some older devices especially budget or entry level devices, don't include a top of the line interface for a given standard and thus will be subject to suppressed read write speeds in the device. The main advantage of using a card capable of utilising the camera's internal speeds optimally is the time it takes to clear the devices buffers. Once that has been obtained then faster becomes pointless in the field.
One good test is to set up continuous raw shooting on the camera, and let it rip so that it slows down to buffer clearance and see how many FPS it can maintain in that state, cards which maximise the bandwidth of the internal reader/writer will be able to maintain a faster FPS than if the card is limiting the bandwidth.
If your camera can handle UHS-II natively, then it's silly buying UHS-I cards for anything other than as backup cards if you need the increased speeds internally, if you don't then it's pointless paying more for speeds you will never use. Which is the better choice is determined by the use case scenario. If you never hit buffer slowdowns continuous shooting or don't use high bitrate video, then you may never need the faster speeds.
A specific test case I just did is the D5300 with an Extreme pro and an Ultra card, once I hit the buffer being filled (about 5-6 shots) the Extreme pro was able to maintain at least one shot every second while the Ultra card took roughly 3 seconds between shots. Given that the 5300 is UHS-I compliant (i.e. faster than 25MB/s of the standard SD interface) and is reported to be able to attain at least 50MB/s continuous write (slower than a good card reader) using timed buffer testing which is slower than the max write speeds of 90MB/s of the card and the 104 of the standard, it can be said that the 5300 only has an average read/write interface in the technology it is using, but is roughly the same as a low priced USB 3.0 UHS-1 reader (the transend is actually a good UHS-1 reader writer, just not an excellent one) and just enough to saturate the USB 2.0 interface on the camera. The extreme pro cards I have using the transend USB 3 UHS-I reader writer I have will read at about 90 MB/s and write at around 80MB/s which is roughly 10% below the maximum ratings of the card. Other budget reader writers I have used can barely get half that on writes (often less than 30MB/s) and aren't much better at reading.
Glad someone mentioned camera interfaces/write speeds here.
Xackly
Also your chart still has read and write speeds swapped, but that's not a huge issue haha
Dammit!
so here is the thing, what does your camera like best? transferring photos isn't what bite my shorts it is waiting for the buffer to clear when i'm shooting. some of the newer cards are not any faster than the older cards. they can even be slower if the camera can't talk to the card well. so get the best card for your camera and have fun.
What cracks me up... being in the computer field area, many of us know this and know how to read memory cards, however it is a BIG MISS even for us to translate what we now think of as common knowledge to another industry that must rely on memory cards. So glad you cleared it up for THIS industry and in a very authentic way using a 'real world' test. Great Job! Love the fact that you also CALL out the haters :) Even as my marketing coach has said... any form of advertising is STILL advertising and in this day in age, controversial comments can do a lot to build awareness and you gain a lot of CRED when you show growth in front of the masses at that point. Great job again!
A few questions:
1. How is the performance with the onboard card readers that many Windows laptops have?
2. Write speed in camera is what really matters to me. There are times when I am shooting something in motion, and the camera can slow down because stills are backed up as the camera tries to write to the card. How does in-camera performance look? I find that the faster cards are helpful if I am doing burst shooting -- the kind of shooting you might do with wildlife or sports. But I'm still not sure the cost difference is worth it. (For example, the fastest Sony SD 128 Gb card is over $220 !)
3. How does performance go if you attached the memory card reader to a USB hub? (I have a hub that attaches to my computer via USB 3.1 C.)
Nice job on the slightly revised video. It's interesting that the port change allowed for max transfer on the two simultaneous cards. I had no idea on the multiple versions of USB either.
ok, so the usb debate at 7:00 it wont make any difference because i doubt the card reader will even max out the slower usb 3 speed so plugging it into a faster port will not make it read faster.
Double sided tape + magnet = $3.00

Serial printer cable? Last time I used a printer before the USB came it, it had a parallel centronics connection. Serial printers... I've never seen one with an RS-232 connection, even though I've seen some software offering support.
Good test and good humility. Kudos and thanks for the info!
The reason the write test was faster to transfer using the better card reader (as supposed to the Transcend) with the Sandisk is because of caching. The computer or memory card will cache the data so a recently accessed item will transfer quicker. A better test would have been to either reformat the card, or clear the cache on the computer.
In my humble opinion, your credibility as a reviewer shot right to the top with this one.
Now subscibed
Thanks ☆☆☆☆☆
Transcend has 4 card readers that look like the reader you used. Only 1 (the RDF9) can read UHS II cards at full speed. Were you using the RDF9? Giving a link is not the same thing. It would explain why the Transcend was slower with the Pro Grade UHS II card (it was being read at UHS I speeds). I have extensively tested USB3 card readers (less so USB3.1 readers), they are all very close in performance.
Have you tested the Sony "Though" cards?
I commented on the first video and came to your defense. haha I fully understood the methodology of your test and it appears others didn't. It's UA-cam and some people are only on here because they can't read - so we have to remember that and hold their hand sometimes. Glad you uploaded this video again.
P.S. Please make another comical video like your hipster Nikon DF review...possibly the greatest video on UA-cam.
That's crazy I also had no idea that the card reader has such a big impact on transfer speeds. Great video Lee.
You wont believe,by how much....
I was lucky to get very fast reader with memory card. Also alway use direct usb readers without cable IT DOES MATTER!!!
Excellent video. I often wondered what diff it made for the device you were using to read/write to your memory card, you answered my question exactly. But I have a question - what if your camera only uses film? ha ha ha........oh oh oh, I saw some really nice cameras that used glass negatives - ha ha ha....oh different subject, different topic on antique cameras. cutting age 1800's style. If you shop around you can find used sdxc cards for a lot less than new ones !

Didn’t see the first review but this one is really helpful. I, like you incorrectly assumed “a card reader is a card reader”...huhh. Who knew? Most importantly, I had no idea what the V number meant and so that information is gold. Takes a lot of the mystery out of shopping for SD cards. Thanks for taking the time to not only review once, but twice!
Question: why do you have two unifying receivers in the same PC? You know you can connect up to 7 devices on a single dongle?

Great video! This information helped me out with my decision on upgrading my SD cards and reader. 👍
Having worked in a high-end camera store for over 6 years, I can say one of the most frustrating things to sell is memory cards.
We dealt mainly in C.Fast and SDXC cards, and about 70% of the time the customer would choose the wrong card.
Keep in mind, our customer base was primarily small-to-medium business owners, often with more money than sense, having had their finger off the pulse for many years, focusing on building their business instead of actually shooting and keeping up to speed. Trying to carefully explain to this kind of person that they're wrong, the number on the box doesn't matter and they'll have to spend about 4x that price to suit their needs was a perpetual nightmare.
I'd say about half of those customers thought we were trying to finesse them into buying a higher priced item which they didn't really need, so they would buy 30 or so of the cheaper cards only to come back in a couple of days with a head full of steam, ranting and raving about false advertising, accusing us of selling counterfeit cards, demanding refunds, etc etc.
Seemed that you are wrong AND not good at explaining. The numbers on the boxes do matter and are easy to understand. Get another job.
Hi, I tested the Prograde Dual SD card reader with provided USB C cable on Macbook Pro 13" 2019 2.8ghz with Sony SFG 64GB UHSII cards rated at 300m/b read and write. I copied 13.53gb of RAW files from one card to the laptop and got a transfer rate of 251 megabytes per second. (13.53gb in 53.74 seconds). I then copied combined 12.72 gb of data from two cards and got a transfer rate of 318.63 mb/s from two cards. Any idea why the data transfer rate was not higher? This is not even close to saturating the USB C cable. I have been using the StarTech 2SD4FCRU3 Dual-Slot SD Card Reader/Writer - USB 3.0 - SD 4.0, UHS II for a while and this does not seem to be worth twice the price due to the lack of boost. Perhaps it is time for a Prograde vs. StarTech, The Real Truth video. At least I got a fridge magnet with the Prograde.
The reader makes a difference because unlike compact flash, SD cards don't have the controller built-in. It relies on the reader's controller
Cudos for redoing the test and being honest to yourself and the audience. I really appreciate that ;)

Lee, I have the same Transcend reader you have, if you look closely at yours, it says "USB 3.0", but the current model Amazon sells says "USB 3.1/3.0". That means the current model was silently upgraded, but the specs on Amazon match USB 3.1 performance.

@@LesChroniquesDeGeorge When you look at it in terms of cost to make it do you think that represents the totality of the cost? Is cost only raw materials and labor? Cost is much more complex than that. Research is a massive cost that needs to be offset. They spend millions of dollars for years in product development. You did not include that in the cost. Marketing that cost. When they sell it to B&H of whoever that was not 3800. When the camera breaks that is a cost to service the warranty, on and on. Why do people look at only cost to manufacture? With the Macs they just ripping you off, no idea on EARTH why you would need them to edit a photo. you just complained about cost and invested in the largest con on Earth "You need a mac"con.

Wondering how you're getting slower speeds with Extreme Pro 95Mbps cards?
because he is an idiot! he is promoting the prograde obviously! i'm not saying he do it intentionally but in the end everybody is going to think sandisk and transcend are garbage and the prograde is so good!
Did you ensure that both reader devices are using the same driver? If not that is where at least some of the difference could be coming frorm. There needs to be some explanation for why the cheaper reader went form fast, to slow, to fast again... all during the same test.
like the magnet thing? buy one and glue it with loctite
I bought a Sony Tough Sd card which claims to be faster than that prograde one - but then it might just be marketing spiel as I don't understand the numbers - it's claimed to be stronger (harder to actually snap/break) than others and water/dustproof too.
Have you tried them? Mine is only 32gb and I use the slower cards in the second slot for jpegs.
Not sure if it it's any speedier in camera as I only do single shot stuff (though a lot of) but it does seem quicker on download to disc.
You also should've used a RAM disk instead of your system SSD. This eliminates some variable factors such as a Windows update downloading in the background slowing down your drive.
Should I be using a memory card reader into my MacBook Pro? Will this transfer quicker? I currently just stick the SSD straight into my laptop
I loved the magnet idea so much that I put a big-ass magnet on my external HDD. Now my one and only backup of all my family photos is completely safe.
not really because having magnets near any memory device is not great.
You also need a Backup of your family photos because if that HDD gets damaged or fails and you cant get data recovery then you would lose ALL of your Photos FOREVER!!!! that's a no brainer!

So I had to spend 3 times the price for a properly fast SD card. How quickly it unloads, have been less of an issue. In camera performance is the main concern.

@@lorenzoamato953 There are plenty go better options out there.

question, does your older cheap reader even have the ability to utilize the extra connectors on that pro grade card? For example if you bought a cheap reader that had the ability to use those extra connectors it might be just as fast as the prograde still.......
Can't help the knee-jerk reaction, but this still feels like a commercial to sell a product that was given to you
I think for your test to be totally accurate the readers need to have the same capabilities on all accounts one brand name one cheap o.
Can you redo the test again? You mislabeled the Sandisk's read/write speeds on the notes in the video.
I don't quite understand the minimum write speed for a card. What exactly does that limit mean? If a camera, or card reader, tries to write at a slower speed it will fail? Why should I be concerned with minimum write speed. (I use a Canon 60D)
(I'm sorry for calling you out.) Thanks Lee for covering it again.
I am so glad that you included the information that starts at 10:06.
Transfer speeds between the card and computer are fine and interesting, but it's the transfer speed from the camera to the card that is ALL IMPORTANT. If the camera overwhelms the card and stops recording, you'll have diddly-squat to transfer from the card to the computer.
A factor that's important to me, DURABILITY. I wish there's a way to simulate the test on durability. I'm even willing to sacrifice some speed for more durability.
Fstoppers : Thank you for this informative video on memory cards , not everyone is a pro at photography and the equipment necessary to excel in this digital world !

THANK YOU SO MUCH
Dude.... I think you are fair.... love the vid.
Good video, but I think you neglected to point out one very important criteria - can your camera utilize UHS-II cards? I know that mine cannot. Pretty much any camera over 3 years old (and even a lot of current models) are limited to UHS-I, so getting that faster UHS-II card may not make any difference in how fast you can write to the card in your camera (V60 or V90, for example), although it will certainly give you faster write speeds to your computer.
Only problem I have with this test is that you should have also used some much bigger files of 20gb or so to se if it can sustain speed over a long time, other than that buying better card readers after this^^
...you compared a UHS I to a UHS II no wonder the ProGrade SD is faster in all respects lol. My question is does that matter for Camera's like the 550D or 7D, etc for video?

Question - what would most likely be faster - the SD card reader in your laptop or PC or something like the Prograde plugged into a USB port (assuming fast USB port)? TIA.
Interesting video. Great job :-)
Depends. If you're comparing two cards with the same read/write speeds (or very similar) then the more expensive one might be a rip-off, but if you're comparing a card that writes say 200 MB/s versus one that writes 90MB/s but the one that writes 200 MB/s is twice as much, that might be worth it if you do a lot of burst shooting and need the write speeds. Where it wouldn't probably make sense is if the cheaper one wrote 170 and the expensive one wrote 200, as that's not really that much of a difference for twice the price for example. To save money, I've bought a mixture: faster cards for when I'm doing things like wildlife or sports where I'm burst shooting a lot, and slower cards for when I'm doing things like landscape where I don't usually shoot bursts (if at all) and write speed is not critical. Granted this doesn't save a ton, but for larger cards, buy slower cards for when you don't need super fast write speeds can save a fair amount of money (for example, a slower 128GB Sandisk card can be about $30 that writes only 45MB/s let's say, versus about $200 for the faster one that writes 250 MB/s).

I wonder if a UHS-II card will transfer to a PC faster in the Pro Grade reader than UHS-I even if my Canon Vixia HF G50 camcorder did not write it in UHS-II?
P.S. I thought you are supposed to avoid magnets with SD cards. ???
The title should be “are expensive Sd card reader worth it?”
Windows 10 has some known problems with SD and USB large file transfers..... The particular drivers used make a big difference.. Also the OS will cache the files depending on all sorts of different variables leading to skewed results
Caching is something they should've noted too
Its is quite sad that our lives are now consumed by speed , 20 sec approx - 10 secs approx Good Lord $380 for tens secs I think I would just put the kettle on for a cup of tea. There is always going to be improvements but people are losing prospective....
If you are just starting you buy what you need to get the job done, today you would buy the $80 reader , years before the cheaper one still did the job . In ten years why would you change the $80 reader for a $160 reader if it still does the job....
We are all getting to a point where the idea of money growing on trees is being believed.
Still if you take a job and get paid $ 500 and then spend it on a Card and a reader with all your gear and expenses for twenty second not quite sure how anyone can justify the logic in that.
The company's should be making the improvements ,make the products cheaper in order for people to buy without hesitation instead of just trying to bleed people dry for ten seconds the cost ratio just cannot work... but good to see the comparison.
If you have a 256GB card you are probably going to use a good portion of that (maybe with a 4k video). With the prograde reader you save 12 seconds with just a 1,5GB file, let's say you need to copy 200GB, it's 26 minutes faster, a pretty noticeable improvement, especially if you are a pro...If it's just a hobby, get the cheap one and wait of course :)
PS: i'm sure that a mid level reader (30$ maybe) is as fast as the prograde.
Unfortunately we live in the 4k age. To record with my A7iii on 4k, you need a UHS II card. sure you don't have to buy the 256g ones but if your clients want more then 5 seconds of footage you gotta bite the bullet. People aren't buying this card for the copy speed, they're buying it so they can get the max out of their cameras.
I get your meaning. However, it all adds up once you have a workload that includes 30 odd cards at a time and people want it out asap.

How about trying the same tests, but using the ProGrade reader first, then the Transcend reader next?
Anyone remember transferring tape in real-time, we have gotten so spoiled..
Me. Filming for a day. Around 4x 41min DVcam tapes capturing on a Sony DSR-11. Living hell.
You should have tried to unmount (or safe remove) the cards after the write tests. I have no experience with windows but on linux that will call a sync operation which will require to flush ALL the caches.... and sometimes it takes a lot of time of extra time. What if your expensive reader has a much larger cache and tricks your pc into believing that the transfer is completed while it is actually still writing on the card???
I just put my cheap SD card into my cheap reader and have a coffee , had a nice coffee and images down .
Stop all the stress and enjoy your photography. Man who really cares.
Are you sure that your cheap Transcend reader is the same one from the B&H page you showed, the RDF9 version, which has the extra set of pins for faster UHS-II cards, and it's not the RDF8 model that doesn't? Because they look exactly the same, only the older model can't go faster than 80MB/s.
It''s old reader from Transcend's RDF8K2 (UHS-I) . New one (RDF9) dont have USB 3.0 lable on the top . On Front label: UHS-II (SD).
The pro reader is faster cause the magnet on the bottom erases some of the data off the card lol
Frequency Studios it’s not tape storage...
Magnets cannot affect solid state storage, as it is not a magnetic storage system.
Camera manuals generally caution using the memory card near areas with strong magnetisation, as the data on the memory card may become damaged. I just wonder whether your prograde reader with the magnetic back has any effect on a card?
There are faster SD cards from sandisk with 300 mb/s
Hey. Where do you copy from? I hope it was previously copied so that it had it in memory/buffers or it originated from ram disk. Everything else I'm thinking your not timing the time to write but the time to read into buffers vs time to read from buffers. Also if I remember correctly it might be stuff in buffers until you have ejected it. Thus the write might not have been finished even if it says it has.
I really would have used linux, turned off buffers and done a dd test and a random access filetrasfer test using the time command. The method you're using is horrible and doesn't give accurate results.
lol did you realy use a calculator to divide 400 by 8 ?
Could you please test how using V30, V60 and V90 cards affect the number of pictures you can take while burst shooting pictures? I own a Sony a6300 and would like to know if I can benefit from upgrading to V60 cards.
Internet people are cruel :D
Your comment offends me.
why would read speeds randomly drop from one reader to the next with the same medium, and go from a hard throttle point from 60 megs to 15? i'm not familiar with this happening under any circumstances i know of.
Is this an advert cleverly disguised as a testing review . Can´t you feel it. i am not a sub maybe you guys know him better.
Thank you for taking the time to review the tests. Can't speak for anyone else, but my comment on the previous version of the video was not to criticize you, but just to state that these "potential errors" had left me unsure about which combination of cards and readers to buy. Thanks again for clarifying!
You don't need 2 Logitech unifying dongle 1 dongle can connect to multiple devices -___-
Could you repeat the tests, but starting with the expensive reader first? I'm afraid some caching is at play here, so the 2nd test each round had some advantage from the previous operation.

GREAT GOOD GOOD CARD.
Love this video and the "redo" aspect. Thanks for doing this and educating the community
Haters gonna hate and creators gonna create.
Possibly stupid question but my computer has a card reader built in from factory, should I opt for an external reader to up the speeds?
