Excellent summary of SD card specs. This stuff blows my mind. I have an old 4K core memory modules as a souvenir of my mainframe computer days. Eight data bits plus one parity bit for each of 4096 locations! Takes as much physical space as several hundred of these SD cards.
Great video, pleasure to watch. Narrated with clear and calm voice and without distracting clips this video is very informative. Also, the tests performed on the SD card are straight forward and easy to copy. This video reminds me how the ICT technology was introduced in 80s :-) Back then there was so much hope for bright future.. :-/ Great work, thank you.
Chris, since you changed the music and graphics you seem a little , well, subdued. You don't seem to be as excited as you were or having as much fun. Your videos are still excellent. There are a number of things I enjoyed about your older presentations. Your excitement when unwrapping a new piece of hardware or finding out an unexpected feature on a simpler board such as one of those $10 computers. The music that hearkened back to early computers. The exciting WHOOOOSH when the next section began. Much of it reminded me of how exciting things were when I had my first Texas Instruments TI-4A computer, when simply having music or hearing speech was an exciting new thing. I just writing this to let you know that you are appreciated and enjoyed, that although I may not tune into every video (the subject affects that), the ones I do watch are very satisfying indeed. (I loved seeing your Wallace & Gromit cup and your snack during a time when you had to wait for something in another video.) I hope everything is all right for you and no great tragedy has befallen you, either related to the channel or personally. I'll be looking for your next video and "I hope to see you again VERY soon".
Up to 2 Terabytes is a very large amount of data for most users. My computer hard drive is just 1 TB. I think it is really amazing how technology has made this possible. I have an 8GB standard SD card for my Kodak Digital camera and have never got past 3 GB of images stored on it, and there were literally several thousand images on it.
@@96blocks On my SD Cards I only record .jpg images. On my computers I do more formats, including the high memory lossless formats, such as .bmp, .png, etc. All 4k means is that the image has a resolution of 4096 pixels in one direction or the other. That resolution allows for some fairly decent large sized images.
Thank you so very much! My Father was the one who always explained the computer and hi-tech world to me. I miss him a lot , but I'm sure he was the one who led my to your vids! Thanks again !

I benefited from this video, and we are in the year 2020 at the time of the Corona pandemic, and you have made this video for nearly 9 years. And the best thing that I benefited from this video is that the sd card cards are hot and cold water resistant even to the freezer and shock resistant and after all these dangerous severe experiences of these memories remain intact and without any significant damage as can be easily hidden in the money wallet and pasted under the table And hide it anywhere we wanted ... it's really cool. You are also wonderful, Mr. Christopher Barnatt

@ExplainingComputers thank you for a quite informative video on the differences in different SD cards and what their differences actually are. I'm expecting you'll make more videos as this one was done 4 years ago.
I loved you video! Not only you taught me what what the product was, but you told me the efficiency of each one, and the value uses of them all at the same time being compact facts that are easy to remember and weren't explained with long facts that I wasn't seeking. Simple, straight forward and very helpful answers, in other words. :)
Your Technology Explanations Are Always The Best! Very Clear, And Easy To Understand For Anyone. I Love Your Channel!! Now, I Haven't Seen All Of Your Videos. So I Have To Ask. Do You Explain Technology Of All Types? For Example: TV'S, Gaming Consoles, Phones, Cameras, ETC. Or Do You Only Stick To Computers And Their Accessories?
Thanks for this. On this channel I only cover computers and directly related accessories and concepts. I do some broader stuff on my ExplainingTheFuture channel.
I love these videos because it's a man who looks like he's from the ninties explaining current-gen technology in a video style resembling that of the early 2000s
Thank you for telling me about this sd card thing.....I found it is very helpful to watching this kind of explanation or tutorials that is very easy to understand it's content....Hope that this kind of videos is continuously make by you so that it will help more people understand about computers and other stuff that included in computing
Came here after you said in the 10yr anniversary video what the recent surgery had done to your throat. Although by comparison to your normal pitch/tone/energy etc you do sound a bit more subdued, unsurprisingly, it was still a great and informative video to watch. One thing about 64gb micro SDs I've found recently is that Windows won't format them FAT32, TP programme required.
Indeed -- and 128GB cards are now on the market -- so 2TB cards are only a few years away now. The max capacity only had to double four times now, and a doubling of maximum capacity seldom takes more than 6 months. :)
Thanks for this. Micro and mini SD cards have exactly the same speed classes (though are harder to find in the higher classes), so, class-for-class, their IO speed is identical.
@elpilito1990 Thanks for your kind feedback. Having bought Sandisk Class 4 cards you may be lucky, as Sandisk cards tend to perform faster than their class rating (which is a guaranteed speed minimum when new). But as you imply, trying to shoot full HD on a class 4 card is hopeful. Fingers crossed! :-)
My favorite use for SD cards is using them to direct windows Temp files, and the other "Personal" files (Pictures/Downloads/etc.), on systems with SSD's, and no other way to extend storage, to help alleviate the write cycles, and extend the life of the SSD.
SDcards are a fantastic option for assisting your SSD. Nowadays, laptops are thinner, and thinner, you don't have space for a secondary mechanical drive, however, all most ALL have an SDcard reader. With the ability to upgrade to, and past 16gb/RAM, swapfiles aren't really necessary. I personally don't use one, and I'm a bit of a "gamer". This is another way to relieve stress on your SSD. :) Glad I could help.
You make a very good point -- SD cards (and other flash memory cards -- though SD is the most popular) do exactly the same job as USB keys. Currently more desktop and laptop OC have USB ports than SD card slots, hence the need for USB keys if you want to carry data between unknown PCs of this type. But increasingly smartphones and tablets are more likely to have a (micro) SD slot and no full-size USB port -- so SD is becoming very widely used.
Good point on making SD cards sort of a "staple" in your media needs. But as of this moment, they are still very pricey specially the mini and micro SD cards like the C10, 32Gb and above capacities . By the way, I learned a lot in through your videos. Thank you! Shalom.
Yes, you are right -- flash memory does degrade the more times it is written to. So important backups should not be stored on highly-used SD cards or flash memory. But flash media with low writes can make an effective part of a backup strategy. I would not for a second suggest not using hard disks. I am just pointing out here that a cheap way to get some additional backup protection for key files (& likely more flood and theft resistant than a hard disk) is to spend a few dollars on an SD card.
Yes, these cards are used in many DSLRs. For most photography I would recommend a class 6 or above SDHC card -- if you shoot HD video, a class 10 card would be better.
To be certain of recording HD video with no problems I would opt for a Class 10 SDHC card. A class six card may well be OK, but could cause problems with recording the 1080p 30fps video that this camera can produce. I see that Hero state that you need a class 4 or above SHDC card for this camera (though that may only work for its SD modes I guess). But the cards Hero sell for the camera via their website are Class 10 Sandisk SDHC. So if it were me I'd buy class 10 if you want to use HD.
Ah, now that is a very good question indeed! I would say that typically class 10 and UHS-1 cards will show significantly better transfer speeds using a USB 3.0 reader. But for class 6 and below cards it will probably not make much difference whether you use a USB 3.0 or USB 2.0 one (although there may be exceptions, as a card's class denotes a minimum speed, and some class 6 cards -- like the Sandisk tested in the video -- are pretty fast).
It would almost certainly be as fast -- but more expensive in terms of cost per gigabyte! However, your idea has been used in practice. For many years Panasonic have sold a high-end solid-state card format called P2 that is used in some pro video cameras. But inside a P2 card are just four high-speed SDHC cards in a RAID config.
Manufacturers do not have to include any class info. Doing do is a guarantee of minimum card performance to that class or below. Cards without class info may work fine, but are not guaranteeing anything. So should be treated with caution if you are storing important data! :)
I don't know. But it is quite possible that an instrument like that may only accept older or lower-spec cards, as manufacturers of non-PC electronics tend to update their hardware far less frequently.
I noticed an update with SD cards. With the Release of the 512 GB SanDisk extreme pro UHS-1 card, SanDisk has released a few cards in the SDHC and I believe SDXC with 2 rows of pins, and the speed class on those cards is UHS-2
Is it a Canon XA10 -- the smallest camera in Canon's pro range -- and shoots 1080p 24Mb AVCHD files to one or two SD cards. Most of the footage in this video is shot with this camera (aside from the shots of the camera itself!).
@charmtecktonik Thanks for this, but I do say "extended capacity". On 4GB "standard" SD cards, while some were manufactured, they were never standards compliant. The technical spec for first generation SD only goes to 2GB. And for a while this did create significant difficulties with device/card compatibilities.
I thought I would see how the inner workings of the card is laid out and how it stores what where and how, plus how it manages video from audio. Also how it knows where and in what order it store information but also how it know exactly where a certain say photo is stored and have it explained visually through step by step example.
SD cards, like any storage device, just store data. So there is no difference between video and audio -- they are encoded into the same file by the camera. Again like all storage devices, there is a file allocation table (FAT) -- a bit like an index -- that keeps track of where each file is.
There are not a lot of devices using SDXC yet. I know the Canon XA10 camcorder that I shot this video on can use them, as can some other camcorders and high-end DSLR cameras. But that's about it at present. And there will be very little reason for many devices ever to require the speed of SDXC.
Old videos are still relevant.

SD cards, like any storage device, just store data. So there is no difference between video and audio -- they are encoded into the same file by the camera. Again like all storage devices, there is a file allocation table (FAT) -- a bit like an index -- that keeps track of where each file is.
There are not a lot of devices using SDXC yet. I know the Canon XA10 camcorder that I shot this video on can use them, as can some other camcorders and high-end DSLR cameras. But that's about it at present. And there will be very little reason for many devices ever to require the speed of SDXC.
Welcome Back Professor Barnatt , I hope your feeling better.
Great video as always.
You should be able to use a 4GB card in a camera that can take SDHC.
It is a write-protect switch. :)
So if I don't have enough space to download something and I use a memory card will I be able to download it
Sehr Gut Erklärt, Danke
Being small is not always a good thing. It's easer to lose somewhere.
True!
