bro can barely work his ipad but knows all about SD cards? 10/10

I just realized this channel only has 150 subscribers. The video quality and content are amazing! Keep doing what you do; I hope this channel becomes big someday!

Couple of bits to expand on this *excellent* vid: 😇 🔒 The *lock switch* at 00:58 is like the _write protect_ tab on audio and video cassettes. It _indicates_ to the reader (cassette deck) that the card _shouldn't_ be written to, but will only work in practice if the reader actually _honours_ what the switch indicates. Many cheaper readers don't detect the switch at all and treat *all* cards as being read/write. 🏃 The *extra contacts* on the UHS-II card at 04:15 support a differential pair data connection (Think SATA-III or USB 3,1) with the host device, and will typically be used by higher-end cameras and professional-oriented card readers - UHS-II cards are intended to serve in a similar way to HDDs or SSDs. All data on a UHS-II card can still be accessed by a regular SDXC compatible reader without the extra data pairs, but data transfer will of course be slower than in your [BigBrand] DSLR. Being a bit of a data monkey I've got SD*C cards spanning pretty much the entire history of the standard up to SDXC, including some that are so old they're original _Class 1_ (Max. 1MB/s, never labelled) cards. These really _don't_ work well in modern applications (That's only to be expected!) but experience shows a Class 2 card from 2006 (With SLC flash) can hold data for longer than a modern SDHC card that uses TLC flash, meaning they're still relevant for high latency long lifetime applications and are especially useful in stereos with an SD card slot. 🎶 The various symbols for indicating the exact same thing (Minimum write speed) have come about simply because the original Class symbol doesn't scale up well to todays transfer rates (You could make a C90 logo, but imagine the C1500 needed for tomorrows 1.5GB/s rates) and the SD Card Forum have basically been throwing ideas at the wall and seeing what sticks. Manufacturers also like to have more symbols to put on their product because it means newer product will _seem_ improved and more advanced compared to what the customer already has, even though the Class 10 micro-SD I've had in one of my phones for over a decade performs just as well today as a brand new Class 10/UHS-1/v30 card would. 😉 But aye, I've learned a few new things from this video! I didn't know that SDUC and UHS-III were on the horizon, and thanks for helping me *finally* understand what _A1_ and _A2_ mean on micro-SDs! No more _trying-and-hoping_ when it comes to expanding my Android device storage with SD cards from now on! 💾📈😁

considering the video quality i was shocked to see so few likes and views on it, nice video.

Finally a video that I actually learn from! KZfaq recommended on fire! Awesome quality from a smaller youtuber. Keep up the good work.

HOLY SHIT THE VIDEO QUALITY IS SO GOOD keep up the good work man!

i really like your casual style with keeping the "blooper" parts in, it makes it feel more casual and natural compared to mainstream stuff. keep up the good work!

Here before bro blows up

The audible "what the f**k" i let out learning about SDUC... 128TB is insane

such an underrated channel

I learned about some of these icons ages ago, your explanation is great. Awesome production quality and nice sense of humor!

this is a well made video ngl, i was really looking for a vid to watch while i snack and this is perfect

I usually don’t like tech videos but this one is pretty cool. I can’t wait to see what this small KZfaqr will do in the future!

Great info I didn't know I ever needed. Keep putting out stuff like this 👍

If you can confirm to me that your opening jingle was done facetiously, then I will be happy to subscribe as a loyal viewer. Jokes aside, new creators with quality videos make me want to join the fray with my channel idea. Keep it up, man.

Can you do more video game videos, on like classic games and consoles?

You are one of the only exceptions to KZfaq’s awful new algorithm. Recommend videos with no views of completely unrelated videos I don’t have an interest in of some random kid filming nothing

Awesome video… I didn’t know any of this about SD cards and it will definitely be super helpful for buying sd cards! Also, I subscribed within the first minute of this video; I’d expect production quality like this from a channel with tens of millions of subs. Keep up the great work 🙌

Thanks for that helpful explanation. I'm saving this to a playlist to reference later.

It's so calming. Thanks for vid)

Dude I was thinking that yesterday, great channel by the way

Damn this was a good video. Also the outro song is really nice, I'm actually having breakfast while watching this lol

hahaha I LOVE how confidently you wrote that "4" down and your brain betrayed you. 🤣 subscribed.

Wow, really good quality video. Love it.

I thought it was channel with 100k subs minimum with the quality and the way u say about it... but u have only 400 subs... keep going and doing what u do, its so well made, it was so good and quality was high, good job man, keep goin !

There is no U2? On this Beautiful Day, that would be Bad! I'll Exit the comments now before I Fall Down.

Thank you. Very informative.

Here before your channel takes off =D keep up the great work (I'm not a bot btw lol)

So cool and informative video 🎉, keep growing 👍🏻

I really liked this video

THOUGHT THIS CHANNEL HAD A MILLION SUBS, KEEP UP THE GOOD WORK

Video quality is superb!

found this video on my home page and it was totally worth it

You appear to be new to this, but your video quality and presentation is outstanding! And you followed the golden rule with close up work...trimmed and clean fingernails! I've seen many videos ruined due to that oversight. Nice attention to detail.

9:34 gotta create those analog horror videos

made me re-think my life choices was so emotional keep it up!

Where did you learn to write your letters from the bottom up? Also, the content surprised me because I thought you were going to talk about all the stuff that fills up the sd card which keeps you from storing the whole 32 gb on them.

Great video i now know how sd cards are actually rated and i even subscribed

Damn dude. I really thought you would have a ton of subs. Was not expecting so little. Should have mentioned (for those who don't know though i have no idea who doesn't at this point) that some sd cards are readers for the minis. Otherwise great video. Loved the intro. 😂

this video rocks!!! ur gonna grow big man

As soon as you showed the wiki chart, i think the reasoning of the "duplication" is since the newer classes have higher "minimum" speeds, they have to still print on the older classes as the cards can still negotiate at lower mimium speeds for that older class. It's all about backwards compatibility and labeling such of what the SD driver chip can actually support

Very interesting, bought an sd card for my modded psp and thought about what the symbols meant. Never bothered looking it up ofc 😅. Sweet video!

You actually covered Application class! No one ever covers those. I use SDs as storage for a lot of embedded stuff and finding good A2 cards is always a pain lol.

printing off my own labels with all the class logos and branding mixed up to flood the 2nd hand market with cards that no one will realise are nonsense until it's too late

Good shit, cheers

When I read the title I actually thought it was about the content they put on it, like a manual in PDF or some kind of autorun shit. Anyway, a really informative video! Well done.

* Probably a coincidence, but the SD card is _also_ shaped like a Nintendo Wii from side view (the real reason for the corner is directional insertion keying, obviously) * The X in SDXC actually stands for *_XTREEEEEME!_* (just like DisneyXD stands for Xtreme Digital) * ...SDUC can do *_WHAT_* now?! Oh man, imagine a max capacity _microSDUC,_ you could fedex an entire Google-scale datacenter in a shoebox! * Also did anyone else think this video was about the junk _data_ that SD cards pre-ship with? Trial backup software and other things...

how does bro have 600 subs with this video quality damm you need more

Here to support you my boi

Your video quality surprised me for the amount of subs you have! good video!

I respect the mustache 👌

Why do I feel like this whole video is a joke when it's not lol

A2 is not always superior to A1. To fully utilize an A2 card, the card reader must support the additional pins for UHS-II. A2 cards often use newer flash technologies such as QLC cells. Their speed relies on caching in a pSLC area. They cannot sustain high IOPS during continuous writes. Additionally, these cards consume more energy, generate more heat, and can have their speed throttled by the controller. QLC cells have only a third of the program/erase cycles compared to TLS flash cells, resulting in lower endurance and earlier defects. A1 cards might still use TLC flash. Another huge factor is the size of the card. A new card with modern flash cells but small size like 32 GB might be a 128 GB card running in pSLC mode or having a huge section of the card that is not visible to the user prolonging its endurance. I usually go for 32GB SanDisk Extreme from a photo gear brick and mortar store or Samsung cards that can be validated to avoid buying fakes.

damn good video man

Hey is that intro song about me??

Finally you're getting the subscribers you deserve....now add a zero and we'll be on a roll! Thank you for always being a reliable, entertaining source of entertainment!

Hey bro, I'm impressed how great your channel and your videos are. Considering you've less than 1k subs (I'm your 501 subscriber btw :D), the quality is pretty high here while able to explain things way simpler and down-to-earth to a lot of non-tech savvy user, and still not going too professional like most big KZfaqrs out there. I'm looking forward for your next video! Cheers :) Edit: you also did videos that are non-tech related too, such as math, philosophies, to name a few. That's really good, I like these kind too!

I THOUGHT IT WAS A MILLION SUB CHANNEL BRO KEEP IT UP

Awesome video! Just curious, what iPad app are you using in the video for drawing?

Awesome video, you are very entertaining. I have the feeling your audio has a lot of clipping, or is that just my headphones?

I want that sad card. Good info/video

Clever idea, with using the overhead camera AND tablet to go through the info and it gives a clean look too

I am watching this video.

What is this intro music! Holy John Mayer, batman. If you keep making this "tech corner" series, you should use that as your theme song.

subscribed for not making me look at a nasty ass screen. also, the info was good!

That was INFORMATIVE!!! And since I did not take notes I'll forget it all in 2 minutes. So... what do I do about that? SUBSCRIBING!!!!!

💡 Possible reason for overlapping type identifiers: The users manual (for older items). It says USE (this type and has a picture). Next time you are in the (button) battery section. look at the packaging. Photo, Medical... and those all have the same exact A76 battery. It is 'The Schwartz'..Merchandising (tnx Mel)

I haven't used an SD card in forever. I mainly use micro SD cards with an adapter and a couple of old CF cards.

I mean, I kinda already knew about everything but wow ❤

if you continue to do this. don't change

Clearly explained thanks! Is crazy when industries have so many different ways of showing the same information, makes it super confusing for the consumer. I stick to known brands and look at Amazon reviews with regards to real world performance.

Remember, that $500 UHC-II card won't have any extra benefits if your device (computer, camera, etc) if it isn't designed for UHC-II because it won't have the extra pins in the card connector. It'll still work as an SDXC, but you won't reach the published speeds.

m-man, who the hell is this dude? why does he make such quality content and have such a small following... h-hmh, g-gotta follow)))

What app is on that on his ipad? Is it onenote or evernote?

Great quality for the number of subs! However I do suggest verifying the subtitles as they seem automated and I noticed a few mistakes.

good to know

There's also SD Express, which is just another higher speed category.

My guess is that there were a lot of instructions that say to get at least a C10 card, so they keep it around.

The microSD in my dashcam has 512 GB, XC I, A2, Class 3 V30.

Underrated channel

BUT what IS all the junk ON the card? Not written on the label but written to the storage medium inside. The cards are never empty.

Really nice video, didn't know that. But how could not address the elephant in the room? There is also a (read?) speed written on the card 😂

The U in SDUC actually stands for Unbelievable. Also, you remind one of the villains in the movie The Rock.

Algorithm bless this man

Can do a video about the stuff/junk that comes loaded on the SD Cards…what happens when you delete the stuff off of SD Card or by keeping them on it… thank you!

Why is this channel so good? with only 400 subs?? Here's some constructive criticism though, please get a separate C-stand for the overhead cam, it is really shaky! Everything else is excellent!

Interesting. They can have such a variance in speed for example Samsung has 3 models with the same symbols that go up from write mb/s speed Select 160, Pro 180, Pro plus 200. each adding an additional $8-10 to the cost.

underrated as fuck

Very engaging, despite being about ...sd cards!

I thought that the reaso for the plethora of symbols is that different device manufacturers use whatever they see fit so the standard has accepted the commonly used symbols to try and reduce the confsuion in this standard amongst end users. It's not helping much but at least they tried.

BTW, that read-protect switch on the side? Yeah, it does nothing to the SD card, the SD card has no idea of the state of the switch. Much like old-school cassette tapes and floppy disks, that switch will either open or leave closed a switch in the SD card connector. It is up to the device to interpret the state of that switch for read/write. (Or in a custom firmware for some Canon cameras, it changes from using the custom firmware off the SD card to using the stock camera firmware in the camera's ROMs.)

Don't for get the 10 works on backwards co patbility readers that are only 10 the 30 is newer readers 30 meg speed think about older readers meaning the 10 means it supports an older reader that's a 10 only

Because device manufacturers have on their devices, throughout the years, were requiring a certain Class of SD cards or a certain U of SD cards. That's why everything is confusing with SD cards.

4 days later… 507 subs….. So fast

Very shocked by the lack of views on this video, incredible content!

nice.... funny wayo making it. Of course, video-speed has also some other meanings, but that was also mainly in the past so for compatibility-reasons they still put it on newer cards too. SD-cards are a quite old system already compared to other tech. And yes, I have some tech that will never run on newer cards or on some cards that don't support the older standards. Sometimes still needed. This includes my DSLR's, some work with the same cards but will not record video's fast enough although they work faster for writing large files from PC's for example. With newer cards and newer equipment, well, it does not matter that much anymore besides the size and just getting a high writing-speed. I also have some cards that cannot read well in my PC, while others do. some newer and some older.... need to switch between readers/writers sometimes depending on card, depending on camera ;------)

I only use microsd with adapter though...

I don't think U1 is exactly the same as class 10, I believe UHS also means the card supports a faster transfer protocol

I thought the video was about preinstalled data. My wife bought an SD card that was unusable in her Mac until popped it into my Linux desktop and deleted everything.

why does bro not have at least 100k subs wtf
