Thank God you're the only one who actually tests USB-C file transfer speeds. All other UA-camrs claim it's 10Gb/s, but the actual transfer speed can depend on the performance of the device's USB-C controller. The Galaxy S23U also supports 5Gb/s, but when you actually transfer a large file, it shows a speed of about 200MB/s in tests. Most tech UA-camrs don't understand this. Could you test Android devices as well, if you have any?
Yes, you are absolutely correct. It’s all down to the enclosure’s controller and the type of SSD being (SATA/NVME) used. Even most off the shelf external drives like the T7, may have the ability for 10Gb/s on its bus speed but the SSD/NAND used can’t go that high. 10Gb/s doesn’t mean anything unless the actual SSD is faster than the controllers and bus speed of the host enclosure and whatever it’s being attached to. I have an S23 Ultra, I’ll do a comparison with this T7 and the iPhone. A lot of tech UA-camrs, including a lot of the bigger ones, don’t understand some of the fundamentals. I’m shocked by how many don’t even understand the difference between a byte and a bit when there talking about speed and storage capacities. Cheers, Dave.
It is faster people have transferred files and the iPhone did it faster it was doing it faster. Also the iPhone is brand new and has a few software bugs.
Hi. Yes, easily fast enough for the ProRes files. I'm still yet to test 4K/60 422 HQ, but the average write speed of the drive is above the requirements for it. The only issue would be any weirdness with the phone or drive and the buffering. However, I've done loads of 422HQ/4K(UHD)25 direct to the T7 and it's been great 👍 Cheers, Dave.
This was just what I needed to be certain that the Samsung T7 works for shooting video with the iPhone 15 Pro Max. I've now bought the hard drive and I am excited about trying it out. Thanks so much for sharing this. Also, as a silly American I am just in awe at how amazing your accent is. Is that Liverpool? It sounds so cool!
I’m glad the video was useful. Yes, well spotted, I am from Liverpool 👍 Locally our accent is known as Scouse. Here’s a bit of background about our Liverpool “Scouse” accent.

I got 653MB/s with a Crucial X10 pro SSD FWIW. I reformatted to APFS from ExFat and it is indeed faster. Thanks for this video, I learned some things. I plugged the Crucial SSD into my Mac Studio and Aja System test lite gave me 905 Write/939 Read. (I used a 20Gbps USB-C cable)
Hi, Jim. That sounds like a nice fast drive to use with your phone 👍 Yes, you will quite often find that APFS is faster, especially with certain SSDs, as you’ve found. Unfortunately, the phone won’t reach the speeds that your Mac will, as you’ve all found out, this is not a problem with the drive, it’s just a limitation of the phone. Keep an eye on the channel I will be doing a video soon that shows a budget 1TB drive that will do about 850 to 900MBs with the phone. Cheers, Dave.
You are very welcome 👍 I’ve been testing a lot of SSDs and have found a number of problems with the 15 Pro Max and a bunch of the drives. However, these T7 drives have been really good and they’re not expensive. I’ll be doing more videos about SSDs and the 15 Pro Max, which show that the T7 is a safe bet. Cheers, Dave.
iPhone 15 pro requires transfer speeds of 220MB/s for recording ProRes, so the 500+ is plenty, like you said. Worth mentioning that you can never transfer a file at the theoretical maximum bandwidth of an interface as there are various protocols required to transfer the data which have an overhead on the data size. Realistically you’re looking at maybe 7.5Gbps throughput max or 937MB/s. Probably less.
Great speeds. I still have a T5 from years ago which I could potentially use for this. I think the speeds will be similar. It's pretty cool that we can hook up drives and use our phones to record high quality videos now.
Alright, Kevin. Yes, the T5 will easily do it. I've recorded a mic test for you that I'll put live on my vlogging channel. It's too late right now to do the intro etc. So I'll do it tomorrow. The adapter cable I've got is great and the lav is great with it and the radio mic is great. I'm really getting into this phone and I'm also prepared to change my workflow for it if I can get shut of that orange tint in the skin tones. Plus, if you put a block off ice under the phone, it's great for WARZONE Mobile 😆 Seriously, I'm having to use one of those blue freezer pack things that you use for keeping food cool in a picnic cooler. The phone hits stupid temps in 5 minutes of WARZONE and totally throttles and goes all mad. Anyway, I've got some beer in the fridge, I'm gong to grab some and get the freezer pack out for some WARZONE 🤣 Cheers, Dave.
@@DavidHarry thanks Dave. The wireless go ii is good and I have the associated lav mic... but I'd happily spend money if something was less hassle to set up. I've not downloaded warzone yet but I'm tempted to connect an Xbox controller up and get a few games👍👍👍
Damsung T7 drives are incredible. I use them as virtual memory on my mac for premiere and resolve. Looking forward to hooking one up to my forthcoming phone 15 pro and Black magic camera app
Nicely done tests. I have two 512GB Samsung T5's from my Blackmagic Pocket Cinema Camera 4K days. Both work quite well with my new iPhone 15 Pro. But, I think I'll pick up a couple 1TB Samsung T7's. I think they're going for about $79 USD at the moment.
Sir I am Watching your all videos because you are a very good Teacher in all segments in electronic and ......😊. Thank you so much for your all testing Classes ❤🙏🏻.
Thank you for the video. Why are you share that you would get higher speeds? Can it be that you are confusing USB-C controller transfer speed with read/write speed of SSD (inside of the iPhone)? The Test speed for Samsung T7 is actually about 1000 MB/s. So the limiting factor here is iPhone. IPhone’s SSD is only capable of those 500 MB/s speed (regardless of USB-C controller). P.S. I extensively tested iPad Pro M1 which has also the thunderbolt port capable of 2500 MB/s write read speed. But iPad’s SSD is also limited to only about 500 MB/s. This is why apple speaks only about USB-C transfer speed, not Device’s transfer speed. People believe they can reach speeds above 1250 MB/s (10 Gb/s), but actually it’s less than half of it - 500 MB/s.
Hi. You are very welcome. Primarily this video was simply to show how the iPhone responds with the T7. Yes, you are correct that such things as the controllers can and will impact the bit rates, regardless of what the manufacturer say their USB ports are. As for the T7. I’ve never seen one perform at 1000MB/s and that’s even using a USB4 host. While 10Gb/s (1250MB/s) is the bus speed for this iPhone, even faster drives are only likely to get about 1000MB/s maximum, usually due to other overheads and of course the controller. Some host controllers also simply just don’t perform very well with the controller/bridge chips in the enclosures. Plus, certain enclosures and their controller/bridge chips don’t play well with certain SSDs. Even using a 40Gb/s (5000MB/s) or 10Gb/s (1250MB/s) dock or hub with the iPhone to connect the external drives, will only result in a maximum of just under 1000Mb/s when using the fastest TB4/USB4 enclosure/NVME SSD combination that’s capable of about 2800MB/s. BTW, as you probably already know, even a TB4/USB4 external SSD with a fast Gen4 NVME SSD in it, will only do about 2800MB/s and not 5000MB/s even if the Gen4 NVME SSD is capable of 7000MB/s on a PC with Gen4 M.2. The difference in bandwidth/data rate on TB4/USB4 is due to an allocation of video bandwidth even if video isn’t being used. So 2800MB/ is the fastest you’ll ever get, even with a super fast NVME inside the enclosure. I’ll be revisiting the T7 again with the iPhone vs MacBook Pro very soon. Also, something else you may find interesting. The iPhone simply won’t see any external SSD if the enclosure is using a Gen4 NVME inside of it. I suspect this a power issue. I thought it may be a PCIe lane issue but the enclosures bridge the NVME to the USB output anyway and other devices see the drive with no problem. I will do a video about this very soon as well. Anyway, thank you for your constructive comment. It makes the time and effort all worth it doing these videos, when some of the people watching the video do understand what’s going on. Cheers, Dave.
Thank you for this video, however I’m still stuck at formatting, the only detail you thought we could handle on our own. 😅 Just trying to save photos and videos from iPhone 15 to this external Samsung drive. Thanks!
Hi, Peggy. If the SSD is not seen by the iPhone you will have to format the SSD with a computer. If you are using a Windows computer then format the SSD to ExFAT, if you are using a Mac computer then format the SSD to APFS. If you plan on using the SSD with both Windows and Mac then format the SSD to ExFAT in either Windows or Mac. Cheers, Dave.
Hi David. I have been using the Samsung T7 with my iPhone 15 Pro Max, to record 4K Log video at 50fps. I noticed that it would often drop frames while filming on the Blackmagic Camera app. Sometimes it was plugged in directly on the phone using a 20-gbps Rixmie USB-C Cable, other times it was plugged in first to a Belkin CONNECT USB-C Hub (also connected to a battery pack and an USB-C mic). I decided to reformat the drive and noticed I was not given Apple File System (APFS) as a choice of format. So I went into Terminal and deleted the MBR and reformatted it as GUID / APFS. Now I've been doing some further tests with the Blackmagic app and I have not gotten any dropped frames. Is this just luck? Or do you think it is possible that formatting the drive as APFS makes it less likely to get dropped frames?
Hi David, as I learned from your video, iPhone doesn't recognize Samsung T7(formatted in exfat) ? Will APFS recognize in both Windows and Android? Can Windows format exfat to APFS? Thank you..
Hi, Charlie. This iPhone is in fact compatible with ExFAT. If you are having problems with ExFAT, I'm not sure why that is. Yes, APFS will work. However, APFS is not something that Windows or Android recognise fully by default. I'm not sure what your issue is. Maybe try formatting the drive again to ExFAT and try both MBR and GUID as the partition mapping scheme and see if either of the partition mapping schemes make a difference. Cheers, Dave.
Proper posh telephone voice this one mate, or no one outside of Liverpool understands me and the Americans have to get translators 😂 Last time I was in Warrington was over 30 years ago for a rave. Legends in Warrington and the State in Liverpool, the two best nights out ever 👍 Cheers, Dave.
I got 300 MB/s max doing the same test. I had a 15 GB file. Worse even is that connecting to different computers gave me speeds of 90-170 MB/s. This is using a TB4 cable plugged into both a TB 3 (2017 13" MBP) and a TB 4 port (Mac mini M1), and a 10 Gb/s cable plugged into a Late 2015 iMac 27". The T7 is capable of 1050/1000 Mb/s R/W speeds. I've gotten those speeds connected to those TB ports so it's not a drive issue. Someone else's comment about the iPhone's drive speeds makes sense as to why it maxed out around 500 MB/s. Apple is replacing my phone because their techs didn't have an answer to this. I'll see what happens with the new phone. It's a bit disingenuous of Apple to tout this "up to 10Gb/s" speed if the device can't actually reach that speed. It's not even 5 Gb/s (625 MB/s), but at least it's close. Maybe raw transfer out of video or other data could reach that speed, but as you mentioned, even ProRes 4k60 doesn't have that data rate.
Hi. I will upload a video soon showing the speed to be much faster than 500MB/s. However. that’s using a powered hub and super fast TB4 SSD but it still does not reach the maximum of the USB C bus speed. So while the phone is definitely faster than 500MB/s, it most certainly isn’t as fast as the bus speed. However, the phone’s performance does get worse when it is powering the external drive. I still have a number of tests to do but I’m now starting to suspect that its storage isn’t as fast as you’d expect it to be. Yes, it is fast but not as fast as the storage on the SoCs for the iPad Pro and Macs. Cheers, Dave.
BTW. I’m also noticing quite slow speeds when connected to a computer for transferring files. I’ll do some videos once I understand a bit better what’s going on. Cheers, Dave.
Hi, Tony. Neither do I. I have never seen it get anywhere near those speeds on anything that I have tested it on, even my Macs and Windows PCs with fast USB C ports. In fact, I've never seen any UA-cam video showing the T7 reaching those speeds. I recently done a video showing the speed of the SK Hynix Beetle X31 USB-C SSD and it is much faster than the T7 ua-cam.com/video/VuUFfiFEnf4/v-deo.html Cheers, Dave.
Cheers@@DavidHarry Neither have I, also did tests on my mac studo m2 max, withe t5 and t7, with thunderbolt cables, never came even close to 1000. But anyways...really love your videos 🙂
@@tonyphotographyvideography Thanks, Tony 👍 Same here, I've tried the T7 on all my Apple Silicon computers with Thunderbolt 4 cables, 40Gb/s USB 4 and high quality 10Gb/s USB C cables and it never performs anywhere near the quoted speed. It doesn't on my Windows PC either. Don't get me wrong, I think it's a good drive, it's super convenient and it stays really cool even with long data dumps but its speeds aren't what you'd expect. If you're looking for a fast external SSD for your Mac, take a look at this video ua-cam.com/video/sV9EDKc5zpk/v-deo.htmlsi=12YJl_9vi8th1PVi I will be doing an update to this video soon with the TBU405Pro M1 enclosure, which has a fan in it and keeps the SSD cool. These Gen 4 NVMe SSDs run really hot. I will be doing another video soon about using the TBU401 enclosure with a Crucial 4TB P3 SSD. This is a Gen 3 NVMe and runs cooler with a passive case like the TBU401. This SSD is the "cheapest" Thunderbolt4/USB4 SSD I've put together. Obviously "cheapest" is a relevant term when talking about anything that's Thunderbolt. As soon as I've caught up with my S24 Ultra video and iPhone 15 Pro Max videos, I'll be doing a bunch of videos about Mac stuff. Cheers, Dave.
Thanks Dave for the test. I was looking forward such test. I just want to mention that 72 GB doesn‘t equal to 72,000 MB but 72 times 1024 MB = 73,728 MB. It doesn‘t change much but should be noted. Just for the sake of my nerdy IT brain. Thanks for the video.
Hi, you are welcome. Unfortunately, your nerdy IT brain may be glitching :) With storage and speed, 1000 (base 10) is indeed the correct measurement. The 1024 binary (base 2) measurement has not been used for a very long time. If you calculate bitrate and capacity using the binary method, you will get a larger speed or capacity and that will mean over estimating speeds and storage and would leave you short on the actual speed or storage available. In fact, base 10 is a legal requirement for ISU conformity. Apple and Samsung most certainly use 1000. Cheers, Dave.
1024 multiplier is used for Gibibytes and Mebibytes. Traditional Gigabytes and Megabytes are base 10, so 1000x multiplier instead. Windows and a lot of other consumer software was using the 1024 multiplier incorrectly and hence the widespread confusion. Like mentioned before, iOS and MacOS uses base 10 multipliers and it’s both correct and convenient once you’re used to it.
@@pooofykittens Hi. You will find that all bitrates, such as drive speeds and internet speeds and all storage capacities are measured in use 10. Plus you will also find that all drive capacities, by the manufacturer, are measured in base 10. This video was clearly talking about Mega/Gigabytes and Mega/Gigabits. Yes, MS may still use binary measurements (which can lead to a lot of problems and conflicts) but that had nothing to do with this video and my reference to the drive capacity was totally correct, also, as per the manufacturer's published specifications. So therefore, your first comment was inaccurate. Sorry to push the point on this one but it was you who brought it up and you were incorrect and I just don't want anyone reading this comment thinking that I don't know what I'm talking about in my videos. Plus, I'm also a nerdy IT type that's been doing it for almost 40 years :) I'm not some random UA-camr with no technical background or experience. Cheers, Dave.
@@DavidHarry Hi David, sorry for not addressing the comment. My response was to grottenolm, trying to explain further why you’re correct in the video. It’s surprisingly common for people to use base 2 in their calculations so I figured it’s useful to mention Mebibytes and where that confusion came from.
How would I go about backing up my new iPhone 13 PM to the external SSD then transferring it to my PC?! I want all my data backed up on my pc stored safely so I can have a fresh new iPhone 15 PM rather using it with 2 years of photos videos etc
I shot a few test videos on my IP15 Promax using the Blackmagic app. at Apple Prores 422HQ, 60fps 4k. The file size came to a ginormous 5.52GB for 30secs of filming. Since I did not have an SSD connected (its my first time), shot everything to the phone. Now I am getting an error transferring the files to SSD - The operation couldn't be completed. File is too large. Any help greatly appreciated!!
Yes, they should definitely have gone with Thunderbolt4/USB4. Now imagine how 15 and 15 Plus users feel when they realise they are only getting a maximum of 480Mbs (60MBs) form their USB C ports and they still won’t be reaching that top speed either. Cheers, Dave.
I think I’m having an issue with my T5… it doesn’t show up in my files app. And it crashes my Mac mini when plugged in. Was working just fine a day ago
It would be interesting if you could use an M2 SSD which easily maxes out the top speed of the phone 😅 Perhaps you could also test out how much power the port is capable of 😄
Dumb question but can I do a full backup of my iPhone to this Samsung t7? I wanna stop paying for iCloud storage? If not, would I plug the ssd into my 2021 MacBook Pro and do it that way?
Not a dumb question. No, there’s a load of stuff that the iPhone won’t let you backup to an external drive, you will have to use the traditional iTunes backup software on a computer or a dedicated iPhone backup app on a computer. It’s really annoying. Cheers, Dave.
Thanks for posting this, very helpful. Unfortunately I keep getting dropped frames when recording 4k60 Log with the T5 - I've tested with various cables and I still get dropped frames (jittery video). Please let me know if anyone else is experiencing any issues with the T5 and what cable worked for you. Now that the T9 is out, I suspect the prices for the T7 will go down, so I will probably invest in one of these. Thanks!
Hi. To make sure that it's your drive that's not supporting the speed. Use the Blackmagic camera app, set it to stop recordingon dropped frames and select ProRes 422 HQ 4K/60 and LOG. If the app stops the recording, this means that it is the drive not being fast enough. If you have already done this, then it will be the drive that's the issue, or the bandwidth from the iPhone. I'm in the process of working out the fastest SSD with a Gen3 NVME and an enclosure. As soon as I find one that will do all the ProRes variations, including 4444, I will post a build video. You may find some of my other videos interesting, as the iPhone itself also has problems with external media. Cheers, Dave.
@@DavidHarry Thanks for reply and troubleshooting tips! I used the Blackmagic app and sure thing, the recording stopped when it detected dropped frames. I then realized that I had one more cable to test with, a thunderbolt cable that came with my LG monitor (lol)...and voila! That one worked, no dropped frames! I will however, buy a shorter and more practical one like you suggested. Looking forward to seeing your tinkering results and thanks again!
@@salvamando1 You are very welcome 👍 Yes, the quality of the cable can also be a factor. I mention using TB4 cables on USB C devices in a recent video because their quality is usually better. However, the usual UA-cam idiots crawl out of the woodwork saying that it's all BS 😆 Happy filming 👍 Cheers, Dave.
@@SanSan-lb9iv Unfortunately I am not familiar with the android version of the app, I don't see why why it shouldn't allow you to record to an external ssd.
hi i tried this ssd with my 15 pro max but i have the errod code "app cant communicate with the helper" a few minutes after the transfer. anyone can help me?
Been trying to find a video on transfer speeds, So what u are saying is the 10Gbps that apple claims, is rare and most the time it is well below that transfer speed?
Basically, yes. The iPhone will not get anywhere near that speed even with a much faster external SSD. I will be doing a video soon comparing it to a MacBook Pro which shows the difference with 10Gb/s. Cheers, Dave.
Can this hard drive be used to back up photos. I have iPhone 13. Was going to upgrade to 15. Do a full restore take everything over to 15 then back up needed but unused phones to this hard drive before deleting them of 13 and 15 for space reasons. Thanks
If you’re using IOS / iPadOS the T7 may not the best option. The Samsung App is not available for IOS/iPadOS. There is no user interface, no password lock, and no way to know how much space is being used on the ssd after you’ve uploaded large sums of data/files. It’s basically a dumb storage box if used on Apple devices with no app support. Sensitive files will need to be encrypted before transferring onto this ssd. I’m disappointed 🥺😭
Hi. That's one of the things I plan on doing once I get around to comparing the Pro Max with my S23 Ultra. However, for this type of speed test there will be very little difference as the T7s maximum speed is about the same as the maximum speed on the S23 Ultra. However, using a faster drive, which I have, will show the S23 Ultra to be half the speed of the Pro Max. The Pro Max operates at 10Gb/s for its USB-C and the S23 Ultra operates at 5Gb/s. However, data management on the S23 Ultra is way better than iOS and iOS can also limit data transfers even when the iPhone is capable of going faster. While Samsung and the S23 Ultra are technically slower, in practice Samsung maximise the use of their data speed and Apple sometimes don't. I also doubt that even though the Pro Max is capable of 10Gb/s, we would actually see that in practice when transferring files. Cheers, Dave.
can you please show the 4k60fps dolby vision data transfer from iphone 15plus dirwctly to external ssd... what spped we get and does the video captures smoothly in ssd or not?
The 15 and the 15 Plus only connect to the external drive at 480Mb/s megabits per second, which is only 60MB/s megabytes per second. They are 20 times slower than the Pro and Pro Max and will not transfer to an external SSD anywhere near as fast and will be limited to what they can record externally, if anything, as I'm not sure what the standard 15 and 15 Plus can actually do and how much Apple may have limited them. Cheers, Dave.
@@DavidHarry Thanks for your reply! also may i know, if i record 4k60fps dolby vision video from iphone 15 plus and then transfer that video to windows PC for editing in premiere pro, does the video quality degrade or remain as it is?
It would be great if you could measure the power to get an idea if it safe to power sata SSD or NvME. My samsung S9 would power some sandisk SSDs but it wasnt powerful enough and risked data corruption. (Can use with a powerbank).
Yes, unfortunately that’s the only way to do it. Just give it a few seconds after your data has finished copying before removing the external storage. I have no idea why Apple don’t have an eject function???? Cheers, Dave.
Jemand ne Ahnung warum das i Phone 15 pro mit einer t9 2tb Festplatte bei einer Video Aufnahme von ca 3-3,5 Stunden immer alleine abbricht ?

I’m shouldn’t matter, since MagSafe is still maxed out at 15W consumed power. However, it doesn’t mean that the updated MagSafe puck with USB-C couldn’t be slightly faster in reality - there’s a noticeable speed variation between various official Made for MagSafe chargers from Apple and 3rd party. I wouldn’t expect anything worth worrying about though, but I’m curious to see a direct comparison. Heat throttling by the iPhone itself would probably mask the difference anyway.
If you could play console quality games (as it seems they are now pushing) with a mouse and keyboard I would go out and get one tomorrow, I'd love that.

Thank God you're the only one who actually tests USB-C file transfer speeds. All other UA-camrs claim it's 10Gb/s, but the actual transfer speed can depend on the performance of the device's USB-C controller. The Galaxy S23U also supports 5Gb/s, but when you actually transfer a large file, it shows a speed of about 200MB/s in tests. Most tech UA-camrs don't understand this. Could you test Android devices as well, if you have any?

iPhone 15 pro requires transfer speeds of 220MB/s for recording ProRes, so the 500+ is plenty, like you said. Worth mentioning that you can never transfer a file at the theoretical maximum bandwidth of an interface as there are various protocols required to transfer the data which have an overhead on the data size. Realistically you’re looking at maybe 7.5Gbps throughput max or 937MB/s. Probably less.
Thank you, Dave! I appreciate your clear and concise videos and your enjoyable commentary.
Nice one 👍 and you are very welcome. Cheers, Dave.
Great speeds. I still have a T5 from years ago which I could potentially use for this. I think the speeds will be similar.
It's pretty cool that we can hook up drives and use our phones to record high quality videos now.
Alright, Kevin. Yes, the T5 will easily do it. I've recorded a mic test for you that I'll put live on my vlogging channel. It's too late right now to do the intro etc. So I'll do it tomorrow. The adapter cable I've got is great and the lav is great with it and the radio mic is great. I'm really getting into this phone and I'm also prepared to change my workflow for it if I can get shut of that orange tint in the skin tones. Plus, if you put a block off ice under the phone, it's great for WARZONE Mobile 😆 Seriously, I'm having to use one of those blue freezer pack things that you use for keeping food cool in a picnic cooler. The phone hits stupid temps in 5 minutes of WARZONE and totally throttles and goes all mad. Anyway, I've got some beer in the fridge, I'm gong to grab some and get the freezer pack out for some WARZONE 🤣 Cheers, Dave.
@@DavidHarry thanks Dave. The wireless go ii is good and I have the associated lav mic... but I'd happily spend money if something was less hassle to set up.
I've not downloaded warzone yet but I'm tempted to connect an Xbox controller up and get a few games👍👍👍
@@DavidHarry oh and I've been reading about the temps. I've not did excessive recording or gaming yet, so haven't seen it get really bad yet.
can you get 40gbps nvme encloshure and with gen 5/4 nvme and test?@@DavidHarry
Not sure if the T5 is faster than the T7, however all my Blackmagic cameras can write raw video on the T5 and not on the T7
Exactly what I was looking for...Thanks
Glad I could help
Damsung T7 drives are incredible. I use them as virtual memory on my mac for premiere and resolve. Looking forward to hooking one up to my forthcoming phone 15 pro and Black magic camera app
Hi. Yes, the T7 is a super useful external drive 👍 Cheers, Dave.
good test! it seems like a good combo!
Alright, Tone. There are faster options but this is super convenient, it works and the drive is really small and handy. Cheers, Dave.
Nicely done tests. I have two 512GB Samsung T5's from my Blackmagic Pocket Cinema Camera 4K days. Both work quite well with my new iPhone 15 Pro. But, I think I'll pick up a couple 1TB Samsung T7's. I think they're going for about $79 USD at the moment.
The T7 drives are really good option for something that's small 👍

Thank you for a very useful video.
Glad it was helpful!
Thank you for the video.
Why are you share that you would get higher speeds? Can it be that you are confusing USB-C controller transfer speed with read/write speed of SSD (inside of the iPhone)?
The Test speed for Samsung T7 is actually about 1000 MB/s. So the limiting factor here is iPhone.
IPhone’s SSD is only capable of those 500 MB/s speed (regardless of USB-C controller).
P.S. I extensively tested iPad Pro M1 which has also the thunderbolt port capable of 2500 MB/s write read speed. But iPad’s SSD is also limited to only about 500 MB/s.
This is why apple speaks only about USB-C transfer speed, not Device’s transfer speed. People believe they can reach speeds above 1250 MB/s (10 Gb/s), but actually it’s less than half of it - 500 MB/s.
Hi. You are very welcome. Primarily this video was simply to show how the iPhone responds with the T7. Yes, you are correct that such things as the controllers can and will impact the bit rates, regardless of what the manufacturer say their USB ports are.
As for the T7. I’ve never seen one perform at 1000MB/s and that’s even using a USB4 host. While 10Gb/s (1250MB/s) is the bus speed for this iPhone, even faster drives are only likely to get about 1000MB/s maximum, usually due to other overheads and of course the controller. Some host controllers also simply just don’t perform very well with the controller/bridge chips in the enclosures. Plus, certain enclosures and their controller/bridge chips don’t play well with certain SSDs.
Even using a 40Gb/s (5000MB/s) or 10Gb/s (1250MB/s) dock or hub with the iPhone to connect the external drives, will only result in a maximum of just under 1000Mb/s when using the fastest TB4/USB4 enclosure/NVME SSD combination that’s capable of about 2800MB/s. BTW, as you probably already know, even a TB4/USB4 external SSD with a fast Gen4 NVME SSD in it, will only do about 2800MB/s and not 5000MB/s even if the Gen4 NVME SSD is capable of 7000MB/s on a PC with Gen4 M.2. The difference in bandwidth/data rate on TB4/USB4 is due to an allocation of video bandwidth even if video isn’t being used. So 2800MB/ is the fastest you’ll ever get, even with a super fast NVME inside the enclosure.
I’ll be revisiting the T7 again with the iPhone vs MacBook Pro very soon.
Also, something else you may find interesting. The iPhone simply won’t see any external SSD if the enclosure is using a Gen4 NVME inside of it. I suspect this a power issue. I thought it may be a PCIe lane issue but the enclosures bridge the NVME to the USB output anyway and other devices see the drive with no problem. I will do a video about this very soon as well.
Anyway, thank you for your constructive comment. It makes the time and effort all worth it doing these videos, when some of the people watching the video do understand what’s going on.
Cheers,
Dave.
Thank you for this video, however I’m still stuck at formatting, the only detail you thought we could handle on our own. 😅 Just trying to save photos and videos from iPhone 15 to this external Samsung drive. Thanks!
Hi, Peggy. If the SSD is not seen by the iPhone you will have to format the SSD with a computer. If you are using a Windows computer then format the SSD to ExFAT, if you are using a Mac computer then format the SSD to APFS. If you plan on using the SSD with both Windows and Mac then format the SSD to ExFAT in either Windows or Mac. Cheers, Dave.
Hi David. I have been using the Samsung T7 with my iPhone 15 Pro Max, to record 4K Log video at 50fps. I noticed that it would often drop frames while filming on the Blackmagic Camera app. Sometimes it was plugged in directly on the phone using a 20-gbps Rixmie USB-C Cable, other times it was plugged in first to a Belkin CONNECT USB-C Hub (also connected to a battery pack and an USB-C mic). I decided to reformat the drive and noticed I was not given Apple File System (APFS) as a choice of format. So I went into Terminal and deleted the MBR and reformatted it as GUID / APFS. Now I've been doing some further tests with the Blackmagic app and I have not gotten any dropped frames. Is this just luck? Or do you think it is possible that formatting the drive as APFS makes it less likely to get dropped frames?
Many thanks, i face the same problem and its resolved by your video
You are very welcome 👍 and thank you for your comment. Cheers, Dave.
This what I wanted in a smartphone
Hi David, as I learned from your video, iPhone doesn't recognize Samsung T7(formatted in exfat) ? Will APFS recognize in both Windows and Android? Can Windows format exfat to APFS? Thank you..
Hi, Charlie. This iPhone is in fact compatible with ExFAT. If you are having problems with ExFAT, I'm not sure why that is. Yes, APFS will work. However, APFS is not something that Windows or Android recognise fully by default. I'm not sure what your issue is. Maybe try formatting the drive again to ExFAT and try both MBR and GUID as the partition mapping scheme and see if either of the partition mapping schemes make a difference. Cheers, Dave.
The problem is Samsung magician on T7, after formatted to exfat now iPhone recognize it. Thank you so much David.
Very instructive
Thank you very much
You are very welcome 👍 Cheers, Dave.
If I'm not mistaken, the iPhone 15 does not have a traditional pinout like the usual UBS-C. So try the original cable from Apple with 240W support.
There's nothing special about the USB C port on the iPhone, a normal USB C 10Gb/s minimum is all that is needed. Cheers, Dave.
Scousers posh telephone voice right here 👆🏼 great video mate really informative 👍🏼 coming from a Warrington half and half over here 🍻
Proper posh telephone voice this one mate, or no one outside of Liverpool understands me and the Americans have to get translators 😂 Last time I was in Warrington was over 30 years ago for a rave. Legends in Warrington and the State in Liverpool, the two best nights out ever 👍 Cheers, Dave.
I love your videos, thank you for sharing
I got 300 MB/s max doing the same test. I had a 15 GB file. Worse even is that connecting to different computers gave me speeds of 90-170 MB/s. This is using a TB4 cable plugged into both a TB 3 (2017 13" MBP) and a TB 4 port (Mac mini M1), and a 10 Gb/s cable plugged into a Late 2015 iMac 27". The T7 is capable of 1050/1000 Mb/s R/W speeds. I've gotten those speeds connected to those TB ports so it's not a drive issue.
Someone else's comment about the iPhone's drive speeds makes sense as to why it maxed out around 500 MB/s. Apple is replacing my phone because their techs didn't have an answer to this. I'll see what happens with the new phone. It's a bit disingenuous of Apple to tout this "up to 10Gb/s" speed if the device can't actually reach that speed. It's not even 5 Gb/s (625 MB/s), but at least it's close. Maybe raw transfer out of video or other data could reach that speed, but as you mentioned, even ProRes 4k60 doesn't have that data rate.
Hi. I will upload a video soon showing the speed to be much faster than 500MB/s. However. that’s using a powered hub and super fast TB4 SSD but it still does not reach the maximum of the USB C bus speed. So while the phone is definitely faster than 500MB/s, it most certainly isn’t as fast as the bus speed. However, the phone’s performance does get worse when it is powering the external drive. I still have a number of tests to do but I’m now starting to suspect that its storage isn’t as fast as you’d expect it to be. Yes, it is fast but not as fast as the storage on the SoCs for the iPad Pro and Macs. Cheers, Dave.
BTW. I’m also noticing quite slow speeds when connected to a computer for transferring files. I’ll do some videos once I understand a bit better what’s going on. Cheers, Dave.
Ok, don't understand why they mention the T7 has read/write speeds of up to 1,000/1,050 MB/s
Hi, Tony. Neither do I. I have never seen it get anywhere near those speeds on anything that I have tested it on, even my Macs and Windows PCs with fast USB C ports. In fact, I've never seen any UA-cam video showing the T7 reaching those speeds. I recently done a video showing the speed of the SK Hynix Beetle X31 USB-C SSD and it is much faster than the T7 ua-cam.com/video/VuUFfiFEnf4/v-deo.html Cheers, Dave.
Cheers@@DavidHarry Neither have I, also did tests on my mac studo m2 max, withe t5 and t7, with thunderbolt cables, never came even close to 1000. But anyways...really love your videos 🙂
@@tonyphotographyvideography Thanks, Tony 👍 Same here, I've tried the T7 on all my Apple Silicon computers with Thunderbolt 4 cables, 40Gb/s USB 4 and high quality 10Gb/s USB C cables and it never performs anywhere near the quoted speed. It doesn't on my Windows PC either. Don't get me wrong, I think it's a good drive, it's super convenient and it stays really cool even with long data dumps but its speeds aren't what you'd expect. If you're looking for a fast external SSD for your Mac, take a look at this video ua-cam.com/video/sV9EDKc5zpk/v-deo.htmlsi=12YJl_9vi8th1PVi I will be doing an update to this video soon with the TBU405Pro M1 enclosure, which has a fan in it and keeps the SSD cool. These Gen 4 NVMe SSDs run really hot. I will be doing another video soon about using the TBU401 enclosure with a Crucial 4TB P3 SSD. This is a Gen 3 NVMe and runs cooler with a passive case like the TBU401. This SSD is the "cheapest" Thunderbolt4/USB4 SSD I've put together. Obviously "cheapest" is a relevant term when talking about anything that's Thunderbolt. As soon as I've caught up with my S24 Ultra video and iPhone 15 Pro Max videos, I'll be doing a bunch of videos about Mac stuff. Cheers, Dave.
Thanks Dave for the test. I was looking forward such test. I just want to mention that 72 GB doesn‘t equal to 72,000 MB but 72 times 1024 MB = 73,728 MB. It doesn‘t change much but should be noted. Just for the sake of my nerdy IT brain. Thanks for the video.
Hi, you are welcome. Unfortunately, your nerdy IT brain may be glitching :) With storage and speed, 1000 (base 10) is indeed the correct measurement. The 1024 binary (base 2) measurement has not been used for a very long time. If you calculate bitrate and capacity using the binary method, you will get a larger speed or capacity and that will mean over estimating speeds and storage and would leave you short on the actual speed or storage available. In fact, base 10 is a legal requirement for ISU conformity. Apple and Samsung most certainly use 1000. Cheers, Dave.
1024 multiplier is used for Gibibytes and Mebibytes. Traditional Gigabytes and Megabytes are base 10, so 1000x multiplier instead. Windows and a lot of other consumer software was using the 1024 multiplier incorrectly and hence the widespread confusion. Like mentioned before, iOS and MacOS uses base 10 multipliers and it’s both correct and convenient once you’re used to it.
@@pooofykittens Hi. You will find that all bitrates, such as drive speeds and internet speeds and all storage capacities are measured in use 10. Plus you will also find that all drive capacities, by the manufacturer, are measured in base 10. This video was clearly talking about Mega/Gigabytes and Mega/Gigabits. Yes, MS may still use binary measurements (which can lead to a lot of problems and conflicts) but that had nothing to do with this video and my reference to the drive capacity was totally correct, also, as per the manufacturer's published specifications. So therefore, your first comment was inaccurate. Sorry to push the point on this one but it was you who brought it up and you were incorrect and I just don't want anyone reading this comment thinking that I don't know what I'm talking about in my videos. Plus, I'm also a nerdy IT type that's been doing it for almost 40 years :) I'm not some random UA-camr with no technical background or experience. Cheers, Dave.
@@DavidHarry Hi David, sorry for not addressing the comment. My response was to grottenolm, trying to explain further why you’re correct in the video. It’s surprisingly common for people to use base 2 in their calculations so I figured it’s useful to mention Mebibytes and where that confusion came from.
@@pooofykittens Cool 👍 Cheers, Dave.
very good! thank you
You are very welcome 👍 Cheers, Dave.
How to get any adapter to charge the phone and use SSD for video recording similtaneously for iPhone 15 Pro Max ??
You need a USB C hub or dock. Cheers, Dave.
Or you can use MagSafe for charging, although it’ll warm up more.
Where buy the ssd and the cable ?
How would I go about backing up my new iPhone 13 PM to the external SSD then transferring it to my PC?!
I want all my data backed up on my pc stored safely so I can have a fresh new iPhone 15 PM rather using it with 2 years of photos videos etc
I have struggled though to get over 600 Mbs with the Samsung T7 on a M1 iMac so that will most likely be the limiting factor as David inferred.
I shot a few test videos on my IP15 Promax using the Blackmagic app. at Apple Prores 422HQ, 60fps 4k. The file size came to a ginormous 5.52GB for 30secs of filming. Since I did not have an SSD connected (its my first time), shot everything to the phone.
Now I am getting an error transferring the files to SSD - The operation couldn't be completed. File is too large.
Any help greatly appreciated!!
Hi. Is your SSD formatted to ExFAT or APFS? Both of these formats can handle large single file sizes. Cheers, Dave.
Could you please try a transfer speed test with a thunderbolt 4 from Apple to a Mac ?
Check my other videos I've done a similar one with a Thunderbolt 4 cable comaparing it to a USB-C cable. Cheers, Dave.
I think this is why they chose 10Gbps for the port, save some $$ and deliver a speed that SSDs have a tough time hitting anyway.
Yes, they should definitely have gone with Thunderbolt4/USB4. Now imagine how 15 and 15 Plus users feel when they realise they are only getting a maximum of 480Mbs (60MBs) form their USB C ports and they still won’t be reaching that top speed either. Cheers, Dave.
I’m here for your beautiful accent meanwhile receiving some knowledge 😂❤❤❤
Both excellent reasons for watching this video 😂👍
How do you safely eject the hard drive from the iPhone without damaging it?
You just disconnect it there’s no eject button
I think I’m having an issue with my T5… it doesn’t show up in my files app. And it crashes my Mac mini when plugged in. Was working just fine a day ago
You forgot to check if the short cable was indeed capable of transfer speeds of 10 Gb.
It would be interesting if you could use an M2 SSD which easily maxes out the top speed of the phone 😅
Perhaps you could also test out how much power the port is capable of 😄
Already done it in another video.
Dumb question but can I do a full backup of my iPhone to this Samsung t7? I wanna stop paying for iCloud storage? If not, would I plug the ssd into my 2021 MacBook Pro and do it that way?
Not a dumb question. No, there’s a load of stuff that the iPhone won’t let you backup to an external drive, you will have to use the traditional iTunes backup software on a computer or a dedicated iPhone backup app on a computer. It’s really annoying. Cheers, Dave.
Thanks for posting this, very helpful. Unfortunately I keep getting dropped frames when recording 4k60 Log with the T5 - I've tested with various cables and I still get dropped frames (jittery video). Please let me know if anyone else is experiencing any issues with the T5 and what cable worked for you. Now that the T9 is out, I suspect the prices for the T7 will go down, so I will probably invest in one of these. Thanks!
Hi. To make sure that it's your drive that's not supporting the speed. Use the Blackmagic camera app, set it to stop recordingon dropped frames and select ProRes 422 HQ 4K/60 and LOG. If the app stops the recording, this means that it is the drive not being fast enough. If you have already done this, then it will be the drive that's the issue, or the bandwidth from the iPhone. I'm in the process of working out the fastest SSD with a Gen3 NVME and an enclosure. As soon as I find one that will do all the ProRes variations, including 4444, I will post a build video. You may find some of my other videos interesting, as the iPhone itself also has problems with external media. Cheers, Dave.
@@DavidHarry Thanks for reply and troubleshooting tips! I used the Blackmagic app and sure thing, the recording stopped when it detected dropped frames. I then realized that I had one more cable to test with, a thunderbolt cable that came with my LG monitor (lol)...and voila! That one worked, no dropped frames! I will however, buy a shorter and more practical one like you suggested. Looking forward to seeing your tinkering results and thanks again!
@@salvamando1 You are very welcome 👍 Yes, the quality of the cable can also be a factor. I mention using TB4 cables on USB C devices in a recent video because their quality is usually better. However, the usual UA-cam idiots crawl out of the woodwork saying that it's all BS 😆 Happy filming 👍 Cheers, Dave.
Does android phones(pixel 7 series or 8 series phones, Samsung ) allow direct recording or transfer files to SSDs? Thanks

Been trying to find a video on transfer speeds, So what u are saying is the 10Gbps that apple claims, is rare and most the time it is well below that transfer speed?
Basically, yes. The iPhone will not get anywhere near that speed even with a much faster external SSD. I will be doing a video soon comparing it to a MacBook Pro which shows the difference with 10Gb/s. Cheers, Dave.

If you’re using IOS / iPadOS the T7 may not the best option. The Samsung App is not available for IOS/iPadOS. There is no user interface, no password lock, and no way to know how much space is being used on the ssd after you’ve uploaded large sums of data/files. It’s basically a dumb storage box if used on Apple devices with no app support. Sensitive files will need to be encrypted before transferring onto this ssd. I’m disappointed 🥺😭
Can you show the same as for s23 ultra file transfer speed test throught usb c T7
Hi. That's one of the things I plan on doing once I get around to comparing the Pro Max with my S23 Ultra. However, for this type of speed test there will be very little difference as the T7s maximum speed is about the same as the maximum speed on the S23 Ultra. However, using a faster drive, which I have, will show the S23 Ultra to be half the speed of the Pro Max. The Pro Max operates at 10Gb/s for its USB-C and the S23 Ultra operates at 5Gb/s. However, data management on the S23 Ultra is way better than iOS and iOS can also limit data transfers even when the iPhone is capable of going faster. While Samsung and the S23 Ultra are technically slower, in practice Samsung maximise the use of their data speed and Apple sometimes don't. I also doubt that even though the Pro Max is capable of 10Gb/s, we would actually see that in practice when transferring files. Cheers, Dave.

The 15 and the 15 Plus only connect to the external drive at 480Mb/s megabits per second, which is only 60MB/s megabytes per second. They are 20 times slower than the Pro and Pro Max and will not transfer to an external SSD anywhere near as fast and will be limited to what they can record externally, if anything, as I'm not sure what the standard 15 and 15 Plus can actually do and how much Apple may have limited them. Cheers, Dave.

Hi. Files moved directly to an external SSD and then attached to a computer and moved to the computer will be the same. Cheers, Dave.
It would be great if you could measure the power to get an idea if it safe to power sata SSD or NvME.

I’m shouldn’t matter, since MagSafe is still maxed out at 15W consumed power. However, it doesn’t mean that the updated MagSafe puck with USB-C couldn’t be slightly faster in reality - there’s a noticeable speed variation between various official Made for MagSafe chargers from Apple and 3rd party. I wouldn’t expect anything worth worrying about though, but I’m curious to see a direct comparison. Heat throttling by the iPhone itself would probably mask the difference anyway.

I've had zero issues with Samsung drives.... However, I would never buy their monitors. Not because they are prone to failure but because Apple makes a much higher quality display 🙂
72GB=73728MB
Not when it’s measured in base 10 as it is with Samsung and Apple, it’s 1000 not 1024.
You sound like your feather is heavier than steel.
but it is 😆

73GB is not 73000 MB. Disliked 👎🏻
Yes it is, both Apple and Samsung measure drive capacity in base 10 not base 2. So measuring in 1000 is correct and 1024 is incorrect.
1 GB = 1024 MB
Nope, it’s 1000MB
interesting video but i dont know what type of crazy people are actually gonna use it for gaming. yeah, aaa-games are coming to iphone but whats the freaking point if switch/steam deck etc already exist, not even taking consoles/laptopc/pc's, and you can buy one AND a nice phone for the same price as 15 pro max. 6,7 inches gaming lololol
What's gaming got to do with anything? This is a SSD speed test.
Well, if i could play AAA games on my phone i definitely would not buy any of these consoles. Some people just enjoy playing on their phone.
