Explaining SD Cards: 2020 Update
ฝัง
- เผยแพร่เมื่อ 1 มิ.ย. 2024
- SD card speed classes, bus interfaces, capacity types and application classes explained, including information on the forthcoming SD Express and SDUC. Video also includes speed tests of SanDisk Extreme PRO UHS-I and UHS-II SD cards.
My follow-up video "Top SBC Micro SD Card" is now uploaded here: • Top SBC Micro SD Card ...
My own preferred SD cards for video work are the SanDisk Extreme PRO models shown in the video, which can be found on Amazon.com here amzn.to/2SSaAL7 and Amazon.co.uk here: www.amazon.co.uk/dp/B07H9J1YX...
Please note that I have no affiliation with SanDisk, that this video is not sponsored, and that I personally purchased all cards and the reader featured in this video.
Talking of the UHS-II reader, it can be found on Amazon.com here: amzn.to/2uGtgFD and Amazon.co.uk here: www.amazon.co.uk/dp/B01MQSR3S... (affiliate links).

I have to admit the SD card interfaces and speeds are not exactly straightforward, naming wise. This video is super helpful for folks that don't keep track of this sort of thing.
@J Lannister could've been worse
''SD ONE Series XC 3.2 Gen 2x2 Super''
USB : someone called me ?!
@J Lannister you forgot about wifi
my question is why are they so greedy . they can easily make terabytes of info on a sd card and yet put such a high price tag on basically the same size sd card with basically the same time invested in its production .
Kind of sad that the USB names and standards are even more confusing now.
128 TERRABYTES on a Micro SD Card?! 😳 That's like a whole lifetime of data, locally stored and accessable offline on a device in the size of a smartwatch! o.O
I can't really fathom that storage number, wow.
Imagine losing a 128TB SD card full of data...
@@user-xr3rb6pn9m
Omg...! 😅
Employee: "Aww... The server crashed! 😔 Everything is gone! Please say we have a backup? 😟"
Boss: "Of course! 🙂 Don't worry! 😊 I have it right here...somewhere? 🤔
....Oh boy. 😐"
I remember when my buddy got a 76 gig hd and I only had 8 gigs. I laughed and asked him what he was going to possibly use that much hd space for. He shrugged and said porn.
Aerox It's already waay too small for a lifetime of data if you have 4k video camera. And I'm sure that in 20 years it will be enough only to install about 12-40 games. Or store about 500h of video. Because as of now 4Tb drive is barely enough for a gaming PC with games over 100Gb in size becoming very common or audio/video workstation, where you have to deal with 24/192 uncompressed audio or even uncompressed 4k video. I have over 90Tb on my NAS and it got 32Tb of free space.
Once again, Mr. Barnatt has taken an *unnecessarily* overly-complicated subject matter and "translated" it into common sense terminology.
I am thankful for Mr. Barnatt's talent and desire to "explain things."

Thanks Thomas.
Thomas is not alone - I think everyone of us!!
I began watching with the expectation of gaining very little information. After a minute I realise I don't know crap about SD cards. Excellent video, thank you!
Exactly! I had no idea about the complexity and marketing tricks involved in SD cards. Thanks, again, Chris, for explaining so clearly and precisely.
Buyer: Hello Mr. Aliexpress seller........does your SD Card has UHS-I or UHS-II?
Aliexpress seller: YES, it cost $1
$1 is obviously fake lol
@Lottery248 - Sir The Velphord Minecraft hence the joke
@@bournejsn yup XD
Really i see many people get scared and bash things like Aliexpress but i bought 3 SD cards from there and they were all fine.
My latest was a 256GB Samsung micro card. I checked the speeds and it is as said. it is 100% original Samsung. Hell it's not even made in China, it is actually really made in Korea.
It seems to me people are just foolish and buy without checking and that's why they get upset.
I really do see them buying from the $1 guy and then screaming how they got scammed by Aliexpress.
I mean. Dude seriously? Just use your damn brain.
@@SIPEROTH Yes you are right. The hard thing with SD cards are still that there is many fakes and bullshit. I once bought an Sandisc 64GB SD card from a huge Swedish onlineshop.
It was cheap but not 1$...it was like 20$ or so. But still cheap this was 2016.
My friend did buy also cards...hes card fail first. Then suddenly my card failed I use it like extended storage to phone and first I thought my phone broke when apps started to behave so strange.
We got our money back. But the worst part is dataloss!!
I bought later from local store with much more money a Toshiba 64gb that still work good in hard use!
Im also using Sandisc that are bought from an finnish store also works 100%.
So they were probably selling fakes in the swedish onlinestore.
I requested this! Thanks for doing all the hard work ;).
It was a good request. :)
@@ExplainingComputers Just watched the video. Great stuff! I hope the upcoming video includes how A1 and A2 compare. Both in benchmarks and real world performance.
Thanks a lot dude. I was searching for this video for a while.
@@ExplainingComputers
Are SD and MicroSD cards have different speeds when are connected into a different port?, like SATA, M.2 or PCIX32 ports through an adapter.
They should do the SD cards double sided working in RAID, and adding RAM for even faster speed.
Two SDXC cards double sided with 2GB RAM cache.
@@frankynakamoto2308 A card inserted into a port of the same rating should run at its maximum speed. But some card readers are a lot slower than others.
I attended an IT course for two years whose cost was around €40,000 (not paid by me). In the whole course they didn't teach me as much as I learned in this one single video. Thank you Christopher. These videos save me a whole lifetime.
We sure have come a long way from the "mind blowing" capacity of Double sided/Double Density floppies... "You're telling me this little floppy will hold a MB of data?" :)
Hopefully they didn’t tell you that, because it would have been a lie! You needed High Density floppies to reach a MB (1.44 MB). But my machine couldn’t read those. I used hundreds of Double sided Double Density floppies, and they would hold only 720KB. Although with the F-copy software for Atari you could format them up to 915KB which worked reliably, but a PC couldn’t read them.
512 Gigabyte is enough for anyone!
F*ck I feel old 😅
First desktop computers I knew of had 8Mb hard drives circa 92
I use to pull out a 1.44 mb floppy and be like boyyyyy... all this space? I got two of them. What a show off in the computer lab.
It's pretty damned amazing the storage density of these little cards, Imagine 2TB on something the size of "like you said the size of a fingernail" The good thing with channel is that it always explains the things you never really thought of and just took for granted. Explaining Computers who'd a thought, 🖖
the amazing part is that its only a figment of ones imagination . if it seems to amazing to be true its most likely not true . most things are more than we could ever comprehend .
Wow ... I didn't know what I didn't know! I think I'm more confused than when I started, but this is the *best compilation of information* that I've seen in one place. After my poor little brain absorbs this I'll go out and buy an ice cream cone!
Explaining computers: explaining everyday tech to everyday people for a smarter purchase and use of the said technology. I'm always thankful for all your effort in making your videos as simple and as helpful as possible. Keep up the great work!
Really a SUPER comprehensive video that explains a complicated subject in a VERY understandable way. Don't you wish all tech explanations were this well explained?
The mark of a true mentor is taking a complicated subject and making it understandable. Great Job.
It's rare you produce a video that garners a reaction other than, "Hmph, everything taught me something", so kudos. You had me pulling SD cards out of stuff just to see what I have.
For a short moment I thought this was a "Technology Connections" video.. still not disappointed.
@@GerardMenvussa that video really helped me understand Brown
Yes, these channels are gold... and also Eta Prime.
I love how apparently we all watch the same channels
@@redpheonix1000 That's what I just thought. Looking up the subscriptions of people here they look pretty much like mine.
SAEM, I love both of these channels.
One of the things I like most about this channel is that out host adds links to earlier and follow-up videos in the description. So many other creators don't bother or forget and I have to search through the channel and try and find the right one. TH-cam's algorithm sometimes helps, but is often off the mark.
These videos are so helpful. Fundamental, logical, to the point, not wasting time. There are to much rambling on youtube, you're not one of those!
I remember getting a Compaq Ipaq and a Lexar 128MB SD card and thinking..."Ooooo this is a lot..." XD
i remember thinking on how foolish most people are when they spent such a high price on a 128 mb sd card back in the day only making themselves lose income while giving it to an already wealthy organisation . when will people ever learn that they are being used .
@@carmichaelmoritz8662 I think a lot of it depends on use. Back then I carried a lot of documents using the handheld for work. :) Also because I got the equipment for work I was able to take the purchase as a business expense.
@@fentonmsu exactly
@@fentonmsu only problem though all my rants are to try and correct the problems of corruption .
The same when I bought my first thumb drive for $ 35 with a whopping 64 Megs 😱
For clear precise explanation of various computer standards and interfaces, your channel is my first stop! Thanks for your efforts!
I am amazed! When my wife and i bought our first computer we paid $300 for a 600mb seagate hard drive. We gave up going to the movies, new clothes, and desserts for three months so that we could play sim city. The android htc phone i'm using is equal to 5 of that kind old computer, maybe more, since its cpu speed was 133mb. I don't play games any more, and i don't surf the net like i used to. Now i mostly watch diy youtube videos. Life is odd these days, Sir. I look around me and I feel like there should be more to it than just this. I will do what i can to make it so. Have a happy Spring, kind Sir.
That drive could sell well on eBay as vintage tech. 😉
Great story. How times -- and technology -- have changed.
Your videos feel like early 2000s tech shows on Channel 4 or Channel 5. But they are actually enjoyable to watch and you don't lose attention.
I miss my college and university days and wish I would had such high quality educational content back then.
Memory storage technology is involving so fast these days that is indeed hard to keep ourselves up to date.
Great video Chris!👍
What a wonderful video, clarifying a confusing topic. I especially liked that when you got to doing testing you told us what tests are comparisons you are going to make and then pretty much went right to the results without making a sit there while you actually ran the tests. Bravo!
I think one of your strongest video qualities is the no nonsense delivery that gets straight to the point with clear experiments and information. It sounds so trivial, but its really refreshing in this day in age where folks have the attention span of a gnat, and every media entity is fighting for your attention.
I really love thorough your videos are. 10 years ago is the last time I really used an SD card or even cared about them and now that I'm purchasing cameras again I have no idea what all of the very confusing numbers and specs and different types are involved. Just after I watched this video I looked on Amazon and I understood all of the price comparison stuff. Most useful video I've seen on this.
Mr. B, thanks again for all your hard work and attention to detail in the preparation of these videos. You are the gold standard, not just for computer related topics, but for training and educational videos in general.
This was a fantastic explanation. Taking out my magnifying glass to read my micro sd cards, I now know why they were so cheap. In practice though, neither my camera, phone, tablet, chromebook, desktop or RPi4 (don't let my wife see the list!) care about the high speeds so, glad I saved the money! One question though; how hot do these fast cards run?
This is one of the most comprhensive; best organized; concise yet completely informative technical reviews I have ever seen !! Thanks a ton !!
A well timed video, Chris! Just yesterday, I was looking back through my "collection" of SD cards and wondering what all the different labels meant, including a few with slightly different form factors, but even more important, what is out there for the future. You presented that in a very clear format. Thank you.
Finally someone cleared that SD card terminology up for me. Thank you.
This channel is the outmost helpful one ever made, thank you for satisfying my curiosity and please do not stop
This is the first time I have actually understood SD card speed and performance specifications. And I've read a few articles on this before. But no one put standards next to each other in an illustration to explain that they build on up each other and a given SD card may be much faster now but it still includes the previous, "old" standard's logo on it with the maximum speed that standard went up to. It all makes sense now (even though SD card speed standards are a mess!). Thank you, sir, excellent explanation!
Once again, a brilliant vid, Christopher! And very timely one, indeed. For last three months, we have been moving data storage (office, home, sbc, smartphones) to faster media and both your previous vid and, of course, this one are very good summaries of the standards lineup. I firmly believe, this vid will be very useful to many people thinking of upgrading data transfer rates. p.s.: an idea for next storage-related vid: add reliability of media (number of writes, water-protection, guarranteed terms of operation etc) to your tests/reviews of sd/ssd. Thank you! And do have a great week!
Timing it’s everything. Storage 👍🏾
Agreed! Greetings my friend.
Short, straightforward and informative. Much obliged.
Can't wait for the part two of this video, in which you will compare MicroSD cards. =)
I know all the information in this video, by heart, actually, but still watched it to the very end because its so well made!
Good job man!
I knew almost of this info, with the exception of the bus information. However the way you explained all of this and presented it was the best I’ve ever seen! Good job!
Definitely looking forward to the boot drive boot camp video! I'm looking to build an rpi cluster now that they've bumped the memory on the cheaper model 4!
Explaining portable storage.
Great explanation of the standards.
It's amazing how far we've come in terms of technology. 128 TB storage, that too in postage stamp size !!
We haven't reached that point yet though. Right now Sd cards are at 1TB the most. So you jumped the gun quite a lot. About 127TB jump.
It will be quite some time to go from 1Tb to 128TB.
We are hoping for a 2TB card by the end 2020, so hopefully we will manage that.
@@SIPEROTH agreed. But we soon will. We already are at 2 TB.
It took about 5 years to reach from 32 GB to 2 TB.
@@SIPEROTH do you know any legit 2tb SD card? I don't think we're already there yet all I find was fake and I think if it is there the price range would be few thousands though
This is the most clearest explanation of the complicated world of SD Cards, Welldone mate!
Thanks. :)
Who'd have thought that storage media the size of my little fingernail could have so varied specification? And we thought cassette tapes were baffling with their "C" numbers and different "Type" oxide makeup, lol.
Thanks Chris for another amazing explanation of it all!
The size of these cards relative to capacity is simply mind blowing. I remember how awestruck I felt when I got my first 1GB spinning platter hard drive! Soon they'll be supplying you with tweezers and a magnifying glass just to be able to handle them. :-O
I remember getting an extra RAM card installed in my first computer (Atari 520ST). It was about the size of my last non-smart mobile phone. And it had ... (hear the drumbeat?) ... Four ... MegaBytes! Ta-dah!
(And it was eight times what the machine had to begin with!)
By contrast, in the first phone I had which allowed inserting a MicroSD I used a four GigaByte card.
I can imagine Linus Tech Tips being upset about how complicated it is. He already hates the USB naming scheme.
Christopher, I have enjoyed your videos and your narrations. Thanks for this video explaining the SD cards. This is something I really needed to know about. Again, great stuff.
One of the best and most informative videos you've done Chris I will watch it again and again till I know all about SD cards!
Thank-you-very-much!!!
I'm about to buy a new sdcard for my camera and was lost trying to understand all the goddamn small numbers and symbols on the labels.
Thanks! Smashing video!
Best explanation and believe me when I say this cause I've been watching these videos for about an hour. No joke
The best video out there about SD cards, the most easily explained and with enough detail. Excellent job abd thanks so much Exploring Computers!!
Thank u Christopher. One of the best reviewers on the youtube. When i first saw your video review it seemed to be so slow. ;) i wanted to skip, but i`m glad i watched till the end. Bravo. u have your unique style, thats vary rare.
I love and really appreciate your explanation of what is essentially a messy and confusing array of classes and standards..... they should hire you to help them sort out their public relations and marketing :-)
love the illustration
Excellent video! Cleared up a few questions I had about the different formats. Looking forward to your microSD boot drive evaluation.
Thank you for the very informative video - I’d completely lost track of all of the SD card versions before watching this.
I’d like to put in a vote for a similar video on all of the WiFi standards!
Thank you. Great explaination. Almost losted in the jungle of these terms before this video.
best tech explaining channel ever!
The one from 9 years ago vs now shows that you never aged.
If only . . .
Great Video 👍🏻
And I’m really looking forward to the Micro SD card video too 😊
Me too
That was utterly brilliant every day is a school day I have learned so much. Good work and congratulations on making your explanation so understandable.
Thank you, Mr. Barnatt for this video. It eased my mind distinguishing all those complicated sd standards.
Thank you for adding clarity and meaning to all the little pictograms that adorn SD cards.
A much needed video which finally cleared all of my confusions.
Hats off to you Sir...
Yes well it be nice for the Pi to add a UHS-II interface for the Micro SD Slot as well maybe improve on the Video Connectors.
Or Adriano
England 91 Arduino?
why ? is it that the sd card is not already small enough . just get the sd card adaptor . the smaller it is the easier it is to lose . those sd cards are small enough as it is . those micro sd cards are just a joke of sight .
most people get sucked into faster is better . rushing through life . when will it ever be fast enough to please the fools .
I don’t think the II interface will show up on a Pi soon if the $35 US price point will still be the target
Greetings! In Quebec, there is an archaic expression from the old land: "I will go to bed tonight less stupid". With the greatest respect for this old saying, we must recognize that each of your presentations undeniably contributes to the enhancement of our digital knowledge; this last one is a convincing example! Many thanks! It will be very useful.
Greetings from the UK. Great expression.
SD cards came out following MMC cards. The size in the 2 families is identical, and they are compatible in operation, and the difference between the two, is that the SD card is thicker and had added a 'read only' switch that made them 'secure' to accidental writes.
It seems that the use of sd cards in SBCs is driving this innovation. I wish the smart-phone manufacturers would catch on and start putting sd card slots back into new phones. (and bring back the proper 3.5mm headphone jack, too!)
Stop buying phones that take out these features.
@@Thorpe Unfortunately many sheep and idiots that ruin it for the rest of us.
Now we have to live with no exchangeable battery and in a little while without a head phone jack(more and more manufacturers take it out).
Lets not forget IR blaster. It was great controlling your devices from your smartphone but NO, talking emojis and facial recognition are more important than functionality.
If SD cards go away too because morons buy phones without them then i just don't know what to say anymore. Personally my SD card saved me tone of times. I save all my data etc on my Sd card and when i had a few accidents with devices breaking i was saved by having my data on my Sd card and easily transferred them to my next phone.
Yeah yeah, i know cloud storage and bullshit. Sorry no. I don't want to share my data with every company in existence.
Did you do the editing and graphics on your RP4 last week?
PS - That's enough for a whole lot of cat photos!
Yes, last week's video was edited on my Raspberry Pi 4. Everything was done on the Pi, expect for existing graphics like the intro title.
This is the best explanation of this I've ever encountered, in print or on video. Excellent as usual.
Thanks. :)
Without no doubt the most complete and scientific review of SD-cards specifications (& testing). The confusing part between the novices are the UHS U1 and U3 versus UHS I, UHS II, and UHS III.
I agree - it is/was madness to use the “UHS” term in two different kinds of standard for the same device!
I'm excited for the SD Express cards!
The mythical UHS3 Pokemon is in hiding
Catch rate is low but it's stats are phenomenal
Straightforward and informative! I hadn't even realized UHS-II was around. Will be interesting to see the future of storage in SBCs with different NVMe options
incredibly concise and straightforward video! Thank you. i was so confused about sd cards and their class
Are micro sd cards reliable being used as storage for important data? I have so many problems of them crashing and everything lost.
It very much depends on the card -- as I will cover in the follow-up video. A2 and high endurance cards are more reliable and stable.
Alhamdulillah I've never had an SD/microSD card fail on me yet in 10 years. Maybe i haven't stressed them enough, but it does show that time isn't a large enough factor in the death of an SD card
Excellent explaination, thanks!
One facet of micro SD cards that I am really interested in is the reliability. Some companies such as Samsung and Sandisk have started selling "high endurance" cards. I wonder if there is an established measure for this and if there are benchmarks available to indicate reliability in terms of data stored.
This I will be covering in depth in my forthcoming follow-up video.
this is a good point i've not owned many sd cards at all but one that was well under a year old has failed and i lost a lost of video because of it.
imagine a 128 TB card failing.
I want to know this too. I have a RPI 1 that has been running as a sylogger for over 5 years. It has chewed its way through at least 6 32GB SD Cards and is overdue a new one at the moment...
I have gone through 3 cards so far. All 3 stopped writing but still read. The devices don't indicate a problem either.
I remember encoding some music to 8kHz GSM codec in Windows 95 in order to fit it on a single 1.44MB floppy disk to take it into school with me.
How times have changed.
Thanks for the video. It's cleared up a lot of confusion I had about SD cards. You're really good at making things clear!
Fascinating as always. Looking forward to the tests of the boot cards, wonder which will be best to replace the IDE HDDs in older PCs. Love the Sunday releases 👍
What is the fastest card an RPi4 can use? I'm lost when it comes to the new cards!
This I will be testing here soon. Interface is UHS-1
@@ExplainingComputers Thanks Chris I will look forward to this episode!
One often overlooked thing is that you want high random read performance, not only maximum speed is important. I know that Samsung has generally performed the best with random read.
Will you be making a video on Porteus Kiosk?
New to me -- and interesting. I will take a look! :)
The best informational video on Sd Cards!!!! I've spent a lot of time trying to figure out what all those notations meant to get the best performance per price.
I'm really looking forward to see what SD card will you recommend to get the most performance on the Raspberry Pi 4!
Another superb video. Looking forward to seeing the micro SD cards tested on some SBCs.

Imagine a Raspberry pi with a 128 TB USH-II SD card. THAT would be a real breakthrough.
Respberry pi doesn't support such a huge amount of storage
they can already produce 128 tb plus . they release tech slowly so that they can rake in as much from us fools as possible before each so called new release . they gain wealth and enjoy the easy life using us .
@@carmichaelmoritz8662 The issue isn't producers not releasing tech, the issue is the lack of incentive.
The products cost a ton of money (Higher capacity SD cards reach into the hundreds, high capacity SSDs reach further into the hundreds as well), and only serve uses in industry, rather than public consumption. Its possible for the public to get a hold of this tech, they just have to dig. And even then, the use for the public is limited, so the development is towards bigger sizes for industry, or cheaper production of current sizes for public, as by the time the cheaper methods are discovered, would be around the time the public would start having a good use for the large sizes. Such as phones taking 4K pictures or video. Or super games that take up terabytes at a time.
But as of now, the only use for such massive storage is with companies that need to store huge amounts of data, from pictures, to video, to documents.
If a consumer seriously needs 128 TB, they are going to have to find it through someone who sells to companies, or buy a bunch of 10 TB SSDs. Its not a ploy to gain wealth, the industry is lucrative and necessary enough to make them filthy rich to begin with, theres no need to intentionally hold back the technology to gain more money. And even if there was, theres no guarantee everyone would be on board. Especially if there would be a market for it. A company would release a 128 TB drive and be killing it because they would be the only seller, getting 100% of the profit with no competition to stop them.
@@pauldeddens5349 fair enough . so basically its all about getting as much wealth from the suckers as possible on a new item and then selling the same product for a fraction of the cost to give the poor working class a chance . even though the poor working class get a chance to buy the item its still only a way for the company to rake in a bit more for an outdated item . even though tech can be helpful its my belief and i do believe we would be better off without it . if i'm wrong then why do wealthy companies never donate certain items to disabled people that might need those said items . not one company has ever donated anything worth of value to me other than my monthly disability checks .

I enjoyed watching your video. I had laid out all of my SD cards to read their info label and watched your video to determine which should be used for my DashCam and which for my Nikon DSLR. I did test several of my SD cards in my Nikon and found that the "slower" R/W speed cards are put to shame my my most recent purchase of a "faster" speed and class.

For me, longevity is an issue having had a few usb flash drives keel over. So, I would be hesitant to store 2tb of data on an SD card without proper backup however tempting that may be. Perhaps someday we'll have miniature RAIDS made of SD cards.

Thanks Chris for a very informative video There is something about your videos that are truly unique.
Great explanation that I'm sure I'll come back to when I need a new card. The marking on the cards and packaging can be vague and confusing so you really need to know what you're looking for when you buy. The important thing is to know your device and application, and choose the correct type of card to get the best performance from it.
Thank you for the video, but what a mess of labels! And so many overlapping terms...

I didn't know that about SD standards. Now I'm really looking forward to your SBPC boot tests with those microSD cards!
These speeds are very complicated, with the C, U, and V designations, as well as UHS-1 and UHS-2. However, you really unraveled the mystery, and now I have a much better idea of what to look for when I go shopping for an SD card in the future. Thanks a lot!
Little known fact: The non-HC SD Cards in fact went up to 4GB, however the HC 4GB cards were more common.
Some manufacturers indeed made "SD" cards up to 4GB. But they were outside the SD specification (whichi only goes to 2GB), and frequently did not work in many devices! :)
Yup exactly, I remember selling these 4GB ones mostly for GPS navigations to get whole EU map on one card :)
