Explaining SD Cards: 2020 Update

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).

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.

[@shadowflash705]

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.

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.

@@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.

@@BartekSzzz I've been trying to find some 4 gig SDSC cards for exactly that purpose, to fit the complete map of the continental USA into older Garmin and TomTom GPS devices.

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.

[@JeremyArchie]

Well this has certainly been a proper short course for me. It highlighted how much I DIDN'T know about SD cards. Thank you for this. 👍

[@billebest]

Excellent video! Cleared up a few questions I had about the different formats. Looking forward to your microSD boot drive evaluation.

I still remember the massive room with tape drives, at the physics building, when I hauled my 5 boxes of data cards to be run. Or my first external HD, 20mb in a metal shoe box sized container. Ave Caesar!

It contains a really clear and adequate explanation of some technical points [for non-technical people like me]. I liked it.

Thank you, once again, for awesome video and completing my Sundays. Have a good weekend. I look forward to your videos every Sunday. Thank you again.

Babe, m' gonna grab a new SD Card for my cam, am back in a minute Four hours later.... Phone rings... Babe it's me, it takes a little bit longer, can't find the right card...

Time to stop going thru the back catalogue and watch the latest release

[@ExplainingComputers]

:)

[@williamhorton9763]

And then return to the back catalogue until the next release.

[@techman2471]

Great video, cleared up confusion on the type, class, and generation of SD card technology for me. I look forward to the next video on micro SD for SBCs.

[@2chuck]

Awesome explanations, I will keep this video handy anytime I shop for SD cards. Thanks

[@AhnafAbdullah]

They both deal with different aspects of computers, doesn't really make sense to compare

[@brianm6337]

Why would someone want a 2 tb card?? Oh yeah. Stick it in your 8k video camera- it's eaten in 3 seconds. :P

[@AlexParkYT]

Innit. People underestimate the size of high quality data lol

[@FalseDev]

Actually at true 8k 60fps with audio it takes it 6000 seconds to fill 2TB

[@AlexParkYT]

@@FalseDev r/theydidthemath

[@FalseDev]

@@AlexParkYT Yep. It takes about 312MB/s on average. Thanks for the recognition

[@SIPEROTH]

What are you talking about? If you simply download Some youtube videos you find informative or interesting every now and then you will still fill 2TB after a little while. Let alone if you put movies, series, documents, books, photos and videos taken with your phone etc etc. Is easy to fill storage.

[@NPrescott]

This is yet another outstanding video!! I have so many various brands and kinds it's good to understand now what exactly I have available to me. I am super excited for the SD Cards over a TB! That will really open up the market for new micro computers and possibly incredible new cameras in the thousands of MP! :D

[@theprodigy01uk]

Another superb video. Looking forward to seeing the micro SD cards tested on some SBCs.

hey good looking
