great vid, only thing you missed of importance (especially for ppl using sd cards in a phone or steamdeck) is application class. If you using an sd card in those cercumstances is worth it to go for an A2 class card over an A1
You forgot A1 and A2, which indicates the speed of random access, like what happens when you use it as memory in a smartphone for an app or, for example, in the switch
What is also important to mention, the UHS-II and UHS-III have a new row of pins for the new bus, they aren't like PCIe that keeps the same mechanical contacts, but actually changed the amount of pins. They still are backwards compatible on both ends, so if one device does not have the new pins (thus not support UHS-II) they just communicate vie UHS-I or the old SD bus.
Really reminds me a lot of USB where they created an overcomplicated and cryptic series of names, abbreviations, and numbers that mean nothing to most of their customers. I've never paid any mind to these markings at all when shopping for cards, instead I just look for a spec sheet that gives actual values for transfer speeds.
Well, there is a slight difference. Those codes for SD cards worked fine at first, but no one expected the format to live so long. So when existing marking became obsolete and no longer usable, they just did a quick patch, then another and another, so now the standard is just a big patchwork. In other words SD simply outlived its own standards. With USB existing naming did not became obsolete, it would still work for a long time, but the USB consortium wanted better free and confusing advertising so they did just that. On top of that it feels that people behind USB naming just could not get into consensus with each other and just started randomly changing stuff hoping it will work.
An interesting thing about some cheaper standard SD cards is that they are actually micro SD cards in a standard SD adapter. I found this out when one of my SD cards split open and I was both relieved and surprised to find a micro SD inside!
That reminds me of the old 9v batteries that had 6 AAAA batteries inside, those little suckers where impossible or extremely expensive to get in my country and it was just better to extract them from those...
@@josuelservin I wonder what legal rigamarole enables that. I'm yet to see such thing, all 9V batteries I've dismantled so far are either a solid brick thing or the cells are nowhere close in size or termination of AAAs and unusable if disassembled. I assume some loophole makes sticking 6 AAAs into a 9v cell more cost effective from a tax standpoint
How did you manage to miss A1 and A2? These are arguably THE most important specs for cards used for operating systems or gaming. If you're buying a card to use in a Raspberry Pi or other SBC, booting a Linux smartphone, or using to store your game library on your Steam Deck or Switch, the Ax (or Application) mark is important. I don't exactly know what numerical values A1 and A2 refer to but it has to do with random access performance, which is not important when sequentially dumping or reading large video files but is super important when reading a bunch of tiny files from all over the place when you're booting an OS or loading a large game.
I actually think they differ in one other way, that would be endurance. If you buy a regular SD card for your camera or something there's a good chance you'll wear it out really quickly. A high endurance SD card will last much longer
Missed this Information in the video too. It realy makes a big impect in these use cases. When you want to watch your surveillance fotage and recognice your card died. Or you don't need to buy a new card every year.
@@mrofinUtortxoF no, maybe they are quite good, but normal Chips, will never live as long as the special endurance Chips from other manufakturer. With a garanted live experience of 13 years continius writing.
@@Sid_Argon endurance (and then trust the marketing people). Most SD cards sold in my country have 5 year warranty. Do they trust in their product? No, warranty is just included in the price. Does the price of SD cards drop dramatically every year for like 20 years? Yes. So a dead card will not be an issue in 5 years. Once again: endurance is marketing
One of the reasons I prefer microSDs with a SD adapter in my camera is that, by taking the card in and out every day, you ware out the pins on the adapter, not on the card, so you can just switch it for a new one if you need to.
Would love to see another quickie that also touches on durability on the write cycles. How it affects performance or leads to data corruption, and how to know when to toss a card. Glad the channels are back up relatively quickly.
I know for a fact that you don't want to saturate your card with data, nor any kind of storage for that matter (besides maybe the RAM which can take it pretty well) since it might lead to data corruption. So, as a rule of thumb, always leave some space free in your storage device, like a few gigabytes or even more if you have a lot of space, just to be sure.
Many micro-sd cards stop writing altogether when they are "done." That's when you know to destroy and toss it. Samsung sells an ultra-endurance micro-sd card that's not the fastest (but still C10 U3 V30) but lasts greater than 8x more than a typical card.
Now that I'm thinking about it, I've always looked at the back of the box when getting an SD or micro SD card to get all of the necessary info and have been doing this for years. It's saved me a lot of time in the long run since I do a lot of photography as well as having dash cams in my car.
note that support for the slide switch on a standard sd card has to be respected by the device, if the devices chooses it can write regardless of the switch
It's often pointless to get the fastest card, because your device also has its maximum read and write speeds. For example, Steam Deck uses UHS-I so the max speed is about 100 MB/s. I guess something like the Nintendo Switch has similar speeds.
RGB SD cards would be a megaflex. Nobody would ever know until that one friend asks "what size card do you have for your switch?" Only for you to pop that port open and blind them with the rainbow assault of rgb
After learning this… Now you can go watch the Technology Connections video explaining why the SD logs looks like a disk (cd/dvd) when SD cards have nothing to do with those types of disks.
It's these kinds of things that I have to look up every time I have to buy an SD card for my DSLR and I swear each year, they include a new symbol to make things more complicated and aggravating, "what's this new symbol? how fast does that mean? Does my camera even support that speed?". As mentioned in the video, I'd appreciate if there was standardized breakdown of the R/W speeds on the package so I wouldn't have to waste an additional hour googling what the new symbols mean.
My Canon 5DMKII runs on FAT32 Compact Flash. It's limited to a 32GB card size, and cannot format in camera larger than that. But with a CF to SD adapter, you can format to your heart's content. You just have to use a computer and disk manager EVERY time you want to wipe it. The craziest thing is SD is pretty slow when compared to the ancient CF format. You still need a U3/V30 SD card to match the camera's write speed for burst photos.
There is also the fact the the uhs cards also had a different pin layout, where the old ones only have one row on contacts, the uhs cards have two rows to help with the data transfer speed.
This video came right on time! I was just looking for an SD card for my school photography class, and I was so confused about which specs were the best.
I mean.... Yea, but you can also print a QR code on top, and each dot is the size of a dust grain on the card, and it contains even more information... and if you color the QR code, it looks even more fancy, and in the color, you can save even more information because of the Colorchannel... It is even more confusing as it is now, and absolutely nobody can read the information... but hey, i would appreciate how much information is contained in the "logo"
They started printing the speeds on the cards as well, but in my testing, the actual measured speeds if the newer sandisc 170mbps cards is exactly the same, as their 90mbps ones.. So yeah, even good will isn't good enough
Two questions: 1) Using a MicroSD card in a SD adapter... does it degrade performance (speed) or no impact? 2) Given a number of high endurance marketing, is that something to look out for?
If the manufacturer provides like 20 or 30years of warranty to their cards you can be sure that it will last quite a while. They wouldn't do this else ;) So I'd rather look out for warranty instead of the "high endurance" label.
Zero difference, the adapter is just a straight pass through wiring device, it does not have any electronics in it. The performance still depends on the capabilities of the SD card reader.
This video reminded me of my recent issues with buying storage cards over amazon. I bought 2 and they did in fact read at the proper speeds but they acted like they were end of life with reading and writing errors anytime i tried to do anything including either trying to set it up in a vita mod or try to use it for switch storage. Decided to go with a cheapo brand from someplace local and haven't had a single issue with it. ~.~
Something I always wanted to sit down and do the math on is using the highest capacity microSD cards how of those would fit in a standard 26ft U-Haul box truck. A random thought I came up with after watching an radio observatory I think physically ship their hard drives back to a lab because it was faster than trying to send the data over any sort of online connection.
A note on mounting. If your phone or tablet has an SD card it is very important that any time the card is mounted for read/write it must be synced and unmounted before the device is unmounted. It must be unmounted before it is removed. Failure to do so is liable to corrupt the card. Phones vary.on how well the phone syncs and unmounts the card especially when it shuts down because the battery is exhausted. Don't let.the phone run down all the way.
Imagine having a Nintendo Wii that's fully RGB including the system, SD card, USB for homebrew, etc. Even potentially an RGB theme for the Homebrew Channe;.
I literally just spent time going through these to buy a card for my Steam Deck...you couldn't put this out a couple days early lol. Although the A1/A2 Classes aren't covered in this video which was important to me.
I believe the different markings for speed are there to indicate compliance with a spec. The requirements for video recording differ from image or audio recording so I guess they get certified for the purpose.
I would like to point out that the drive size limit of FAT32 is 2TB, so any SD card that is under 2TB in capacity can be formatted to FAT32 and have their full capacity used by older devices that only support that standard. You need to get software that will let you format them to FAT32 as Windows doesn't let you format anything higher than 32 gigs to that format, but I have multiple 128 gigabyte SD cards and even a 256 gigabyte SD card formatted to FAT32 for compatibility with older devices.
1:00 Warning, the write-protect switch on SD cards and microsSD-adapters aren't guaranteed to do anything. They're literally just a little piece of plastic that you slide around, they have no electronics that connect to the card itself. The write-protection is on the card-reader to detect and honor, which isn't universal. Quality card-readers will usually obey the write-protect switch, but cheap ones (eg most of the Chinese ones on eBay/Amazon) will ignore it and write to the card even if the write-protect switch is set. (Also, many cards and adapters don't even display which direction to flip the switch to write-protect it, so you either have to memorize it or you might end up accidentally getting it backwards.) Incidentally, the write-protect switch on memory-cards works exactly like the write-protect tab or notch on floppy-disks, they were just a piece of plastic and the ability to write or not was incumbent on the drive itself; the difference is there are no reported cases of floppy-drives ignoring the write-protect tab.
Photographer here who's been buying SD cards for 15+ years. Spot on video! I remember in the early days before I educated myself how confusing all the options were. Always check the specs of your device for compatibility, format the card in the device and replace the card before its life cycle is over to ensure you never loose data.
I think they often don't present the lifespan for micro SD cards in TBW like they do with SSD's. Warranty is often a good indication, though. I believe SanDisk offers 5 years for the extreme line-up, so likely 1.5 times that to get the general lifespan. Of course it mainly hangs on usage. Shooting 4k video on a regular basis will wear it out relatively fast, while using it as a game drive on a switch will mean you likely won't ever reach write capacity before the card is worn out of lost.
If you are doing this professionally, you should really be using equipment that writes data to two SD cards simultaneously. Also, the cards might just disable writing to them to protect themselves, so hopefully the camera throws up an error and you can easily just read what data you put on it up until that point.
Important thing is not to buy a card that your device does not support like UHS-II if the camera supports only UHS-I. You will not get any extra benefit but pay extra.Typically the manual of your camera tells what cards are recommended. Also from time to time do a full format on the camera to the card. That speeds it up. Do not do it on a PC, that would take ages and it would not help.
Very Informative. I actually learned something about SD cards that I honestly did not know about them. Thanks guys. I now know what card I'm after for my phone upgrade. 💯
V actually shows minimal write speed. Eg. V30 actually has 30MB/sec minimum, so V30 can have 60MB/sec, because if it goes lower then 30 it will break your 4K video recording. V90 can have 105 or 120 or 180MB/sec, or anything above V mark. You also forgot to mention A1 and A2, as well as price difference with all this things, because normal people get the best deal you know, like class 1 with 256GB capacity or so, and peoples usually do not understand the point when someone pay very expensive micro SD and gets very small memory, something like 128GB, UHS 2, U3, V30, A2, two times less capacity, five times more expensive, because class 1 is the highest grade, 1st class baby.
Successfully gotten 128GB XC cards to work (at full size) in tablets claiming a HC limit of 32GB before by formatting to Fat32. It's a nice little cheat 🙂
I recently went down this rabbit hole after a PLC controller I work with needed a new SD card. I asked what size and they asked for a 128 gig, but looking at the card I noticed that the pinout was different and found out that it was a CFast SD card. The price on these are ~ 10X the normal SD. I bought a 128 gig for ~ $110! Ouch
If you buy your SD card from Amazon, you can pretty ignore all of the symbols because the card's fake and you shouldn't even trust the capacity, let alone the speed.
One thing this video didn't cover is the read versus write speed. This is super confusing because these SD cards will have big flashy numbers telling you the read speed but that doesn't mean a camera can write at that speed.
@@pokepress I don't think they ever got to it :( For example - most SanDisk cards will say 90 MB/s or 120 MB/s or whatever in plain language - then the write speeds are cryptic Class 10, U3, V30 codes.
@@FilmmakerIQ Because write speed matters, so of course they will be cryptic about it. They can't just TELL you both speeds. That would be helpful to the consumer.
As a photographer, the non pro cards are a nightmare to compare since you have to go to the manufacturers web site to dig out what the write speed is, since this is the most important metric yet most non pro cards only show read speed which is pointless and mostly meaningless marketing crap
From worst to best for Capacity & Speed : Capacity - SD (outdated) SDHC SDXC SDUC (the above four don’t matter too much since you’re most likely to look at the capacity number anyway) Speed - C2 (outdated) C4 (outdated) C6 (outdated) C8 (outdated) C10 U1 U3 V6 (outdated) V10 V30 V60 V90 UHS-I UHS-II UHS-III UHS-EX

Two questions: 1) Using a MicroSD card in a SD adapter... does it degrade performance (speed) or no impact? 2) Given a number of high endurance marketing, is that something to look out for?
I believe it's just a simple pass-through device, just lining up the contacts between the SD card slot and the Micro SD card.
For endurance claims just check the warranty. If they don't trust their own product to hold up then why should you?
If the manufacturer provides like 20 or 30years of warranty to their cards you can be sure that it will last quite a while. They wouldn't do this else ;)

So glad that all the tech tips channels are back on line
Riley I'm pretty sure that SD Express is not 1 TB/s. 4:18
1:00 Warning, the write-protect switch on SD cards and microsSD-adapters aren't guaranteed to do anything. They're literally just a little piece of plastic that you slide around, they have no electronics that connect to the card itself. The write-protection is on the card-reader to detect and honor, which isn't universal. Quality card-readers will usually obey the write-protect switch, but cheap ones (eg most of the Chinese ones on eBay/Amazon) will ignore it and write to the card even if the write-protect switch is set.
(Also, many cards and adapters don't even display which direction to flip the switch to write-protect it, so you either have to memorize it or you might end up accidentally getting it backwards.)
Incidentally, the write-protect switch on memory-cards works exactly like the write-protect tab or notch on floppy-disks, they were just a piece of plastic and the ability to write or not was incumbent on the drive itself; the difference is there are no reported cases of floppy-drives ignoring the write-protect tab.
am so happy that this channel is back
Usually people buy based of: 1) Size 2) Which is the cheapest for that price XD
"Why is your phones batterys so often low?"
"Because of the RGB Micro-SD card in it, that you can´t see."
When I write hieroglyphics I like to brag about all the headshots I got on tickrate servers back in nom.
my humor just cracked in the end LMAO!!!!
This makes the USB-IF naming scheme sound reasonable
Simple, clear, to the point, and very helpful. Thanks!
4:17 Surely Riley meant to say 1 GIGABYTE per second here and not 1 TERABYTE per second. That would be ludicrous.
You mentioned UHS numbers but made no mention of the second row of contacts on the back of the cards.
I had to look up a chart for these because the one I bought for my video camera wasn't fast enough.
The SD Card Association is really bad at its job, but we should also talk about people marketing the USB standards. 😆
2:52 to skip ad
Photographer here who's been buying SD cards for 15+ years. Spot on video! I remember in the early days before I educated myself how confusing all the options were.
Always check the specs of your device for compatibility, format the card in the device and replace the card before its life cycle is over to ensure you never loose data.
What's the life cycle of an card? ( SanDisk extreme Pro in my case)
I think they often don't present the lifespan for micro SD cards in TBW like they do with SSD's. Warranty is often a good indication, though. I believe SanDisk offers 5 years for the extreme line-up, so likely 1.5 times that to get the general lifespan.
Of course it mainly hangs on usage. Shooting 4k video on a regular basis will wear it out relatively fast, while using it as a game drive on a switch will mean you likely won't ever reach write capacity before the card is worn out of lost.
Why are we concerned about loose data? Is tight data better?
If you are doing this professionally, you should really be using equipment that writes data to two SD cards simultaneously. Also, the cards might just disable writing to them to protect themselves, so hopefully the camera throws up an error and you can easily just read what data you put on it up until that point.
@Michael I may not have proofread my work..

Great SD Card Reference Video.... Thank You
Important thing is not to buy a card that your device does not support like UHS-II if the camera supports only UHS-I. You will not get any extra benefit but pay extra.Typically the manual of your camera tells what cards are recommended.
Also from time to time do a full format on the camera to the card. That speeds it up. Do not do it on a PC, that would take ages and it would not help.
Very Informative. I actually learned something about SD cards that I honestly did not know about them. Thanks guys. I now know what card I'm after for my phone upgrade. 💯
V actually shows minimal write speed. Eg. V30 actually has 30MB/sec minimum, so V30 can have 60MB/sec, because if it goes lower then 30 it will break your 4K video recording. V90 can have 105 or 120 or 180MB/sec, or anything above V mark. You also forgot to mention A1 and A2, as well as price difference with all this things, because normal people get the best deal you know, like class 1 with 256GB capacity or so, and peoples usually do not understand the point when someone pay very expensive micro SD and gets very small memory, something like 128GB, UHS 2, U3, V30, A2, two times less capacity, five times more expensive, because class 1 is the highest grade, 1st class baby.

1 terabyte a second seems really high. Sources I found online indicate a theoretical max of 4GB/s.
4 GB is still insane
4. aspect is durability (there are the application class ratings for this, especially important in MCU/pi projects)
Thank goodness Techquickie is back again 😊
Nice to see yall are back up and running again!
No mention of Application Performance Class?
Wow, i really REALLY needed this. Thanks so mooosshh!!!!
4:16 ah yes... 1 TB/s SD card made by unicorn I guess
Mini SD is really uncommon
All I know is it's on the 2006 PS3
All jokes aside. This is the best info I've every seen about an SD card. Thanks
"Oh God. RGB SD cards are coming, aren't they?" Not to THIS household! 🤣
Agreed
4:16 "close to 1 TB/s" 🤔🤔🤔
What about A1 and A2? You should complete the confusion. :)
It’s good to have you back TQ
They should just use USB naming : SD XC 3.3 gen4x2
1:01 does the protection protect against viruses ????
Wash SD card at 30 degrees with mild detergent. Do not tumble dry.
Successfully gotten 128GB XC cards to work (at full size) in tablets claiming a HC limit of 32GB before by formatting to Fat32. It's a nice little cheat 🙂
That names made me remember the USB 3.1, C, gen. 1, ver. 2, side b, paragraph d, versicle 9.
I recently went down this rabbit hole after a PLC controller I work with needed a new SD card. I asked what size and they asked for a 128 gig, but looking at the card I noticed that the pinout was different and found out that it was a CFast SD card. The price on these are ~ 10X the normal SD. I bought a 128 gig for ~ $110! Ouch
If you buy your SD card from Amazon, you can pretty ignore all of the symbols because the card's fake and you shouldn't even trust the capacity, let alone the speed.
I have been using V 30's for a long time now, to read/write 4K video with no problems at all.
SD and USB must be long time friends
Welcome back. Glad you guys were able to recover.
Riley gets me all riled up
Linus in the background, “it’s all apples fault”!
I always go for A2 for my steam deck and A1 for android phones in terms.of SD cards I purchase from time to time
One thing this video didn't cover is the read versus write speed. This is super confusing because these SD cards will have big flashy numbers telling you the read speed but that doesn't mean a camera can write at that speed.
They did briefly mention the asymmetry, but yeah, not uncommon in the world of storage.
@@pokepress I don't think they ever got to it :(
For example - most SanDisk cards will say 90 MB/s or 120 MB/s or whatever in plain language - then the write speeds are cryptic Class 10, U3, V30 codes.
@@FilmmakerIQ Because write speed matters, so of course they will be cryptic about it. They can't just TELL you both speeds. That would be helpful to the consumer.
As a photographer, the non pro cards are a nightmare to compare since you have to go to the manufacturers web site to dig out what the write speed is, since this is the most important metric yet most non pro cards only show read speed which is pointless and mostly meaningless marketing crap
From worst to best for Capacity & Speed :

(the above four don’t matter too much since you’re most likely to look at the capacity number anyway)
Speed -
C2 (outdated)
C4 (outdated)
C6 (outdated)
C8 (outdated)
C10
U1
U3
V6 (outdated)
V10
V30
V60
V90
UHS-I
UHS-II
UHS-III
UHS-EX
So, basically, I learned nothing in this video, not because I am a smartass but because we found an industry group worse than hdmi and USB combined
Why not just but MicroSD and use the adapter whenever needed instead of the regular SD card size with less options
Thanks for this ecplanation
Magnet on the back of your phone don't you think that would destroy your battery?
Too bad HDMI can't be this consistent
