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!)
@@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.
Thank you for an update to this interesting subject. 32GB SD card may be a rescue to an old netbook I have got sitting somewhere around, with only 4 GB of flash storage onboard. Finally an occasion to test desktop Android on something
We could probably do with an explanation of SLC/MLC... as well as backwards compatibility between different standards. As it turns out, 2GB cards are very expensive now because some critical legacy equipment cannot support >2GB cards... I assume as time goes on this process will continue.
-let's face it, sd cards are gonna die soon- Mobile phones these days are starting to lose it's micro sd slot and cameras are starting to use 2.5 inch ssds
This is very true -- and one reason for the SD Card Association to set the SD Express standard in place. We're also starting to see cameras that take an M.2 SSD in a caddy.
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.
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. RUclips's algorithm sometimes helps, but is often off the mark.
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 .
Very thorough explanation. Doesn't feel like 20 years ago when SD came out, I remember having a few compact flash and Smart media devices at the time and wondering what would prevail. I don't like the naming convention of SD cards, it is totally convoluted, is it really necessary to say the card can maintain 10mb/s 6 different ways?
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!
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.
Wow, even micro SD cards are now being designed to use the PCIe bus? I didn't know cell phones even had those. I'm not too familiar with mobile technology lol
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 :-)

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...
@ExplainingComputers Would you recommend an sdCard or an eMMC Module for Rock Pi 4 Penta Sata Hat Config? Also do you know if Rock Pi 4 supports UHS-2 speeds? Radxa support won't tell me that, they just recommend the eMMC Module. I'm currently getting around 10MB/s reads and writes, on every thing even downloads. My current boot drive is a sdCard Kingston Class 10 U1. HDD file transfers also around 10MB/s. hdparm gives me normal 100MB/s speed for the SATA HDD over the hat. Power supply is a 4-pin molex with (12@2A + 5V@2A) rated power adapter from a IDE to USB Kit i have. Could it be the sdCard or the problem is power ?
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.
so wait this is confusing...I found a 32GB MICRO SDHC CLASS 10 U3 V30 A1 class 10 is minimum 10mb/s but the U3 and V30 means its minimum 30mb/s right? so what speeds I'm going to get? >_
U3 and V30 indeed means that the card is able to sustain a minimum write speed of 30 MB/s, and that should be the speed of your card. But this means that your card also meets (and exceeds!) the Class 10 requirement of being able to write data at 10 MB/s. So the card can bear both the U3 and Class 10 labels. But the way that this is done on SD cards is indeed confusing and crazy.
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.
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...
Ja Chegamos no Limites Ultrapassados pelo Futuro Infinitos de 320TB ao Infinito ou Seja Dará para Gravar num Único SSD? 300 Anos de Vida de Toda a Humanidades num Único Disco Rígido ou Chipe Digital de Cristal?
Chris, would you have any idea if "good" quality digital cameras like the Nikon D850 or the Olympus OM-D E-M1 really get a boost from UHS II seeing that they're going 4K video at 60FPS..... that's a mighty chunk of data to be flinging onto a card..... Obviously, thanks for another awesome video!!!
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.
Last year, I decided to (finally) replace my Orange Pi's micro-SD with something faster to increase its stability. Bes Buy had SanDisks on sale and I had to choose between a 130MBps C10 A1 V10 or a 95MBps U3 V30 (no A-rating). I figured it was essentially the Pi's hard-drive, so I may as well get the one with the application-rating since that's specifically what it's for but it's very confusing and frustrating that there's multiple attributes and they mix-and-match so there's no distinct "faster" or "better". 😕
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.
Hi, I appreciate if you include ADATA 64GB Premier ONE microSDXC UHS-II U3 Class 10 in your testing. I am using this card on my Jetson Nano and it seems that after a while it becomes slow. Can Jetson Nano accommodate this card?
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.
The best micro sd card for SBC's video will HOPEFULLY be uploaded soon! I will be getting a Raspberry pi 4 soon and i could use the info. Thank you! Looking forward to seeing that.
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
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 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
I have a Nintendo Switch with a Micro SD card used to store games. I am using a 512GB card, and they have now gotten relatively cheap that I have bought a second one of the same capacity. In comparison, I just bought a Xbox One X, the most powerful home console on the market as of writing, today, and it only had a 1TB hard drive in it. It is possible to upgrade that to 2TB, though the process is very difficult. The console will also take remote USB powered hard drives for back up purposes, normally you see these branded at 2TB at most for about twice the price of a 512GB Micro SD. The fact that my portable Switch, which if we are really generous is one third as powerful as an Xbox One, can have half the capacity at a half the price in a format the size of a fingernail and relatively hot swappable... is pretty mind blowing. :-O
We ended magnetic (HDD, VHS, Cassette, FDD) era and started NAND-Flash era. 128TB at size of fingernail with speed up to 1GB/s. What a time to be alive!
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 .
A fun fact is that I have several 16GB Transcends and smaller cheaper cards that been running 24/7 for years without problem. But my 64GB Sandisk ultra died within one year, got a warranty replacement and it too broke within one year (becomes read only). Raspberry Pi can really eat SD cards unless swapping is turned off and tmp/log etc is put on the RAM.
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!
Great stuff dude...a more clear, easy to understand explanation of SD cards i haven't come across. At time of writing 57 thumbs down ????...the peanut gallery that is youtube comments never fails to disappoint me....great information dude...thank you, and peace to ya.
Not so much to learn here, why do I care if I have a faster card when it comes to video, am I right I don’t much have to if I am mainly 1090p or 4k sampling down to 1080p? Looking forward to the OS one though as I am sick and tired of SD card failures on SBC, to the extent a £20 SSD makes all the sense to me over a card. Well made tight video as always though Chris, really proffesional this time, as in paid for quality, can see you making money from this level of presentation (and knowledge).
It sounds very strange to be talking about using the NVMe interface and yet still not maxing out USB 3.0 let alone USB 3.1 gen 2. Not to detract from the amazing advancements that have been made, but it does add to the confusion when people might see that a SATA SSD is faster than an NVMe SD. Manufacturers do like to be a little fuzzy when it comes to trending buzzwords.
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! :)

Have close to 7000 songs on a SanDisk Cruzer Glide 128GB for backup. Is there another better way to save my songs or I should be fine what I have!? I had the flash drive no more than a year. Thanks.
Guess I should be upgrading from my WWII Wire Recorder then ? Seriously I'm clueless on what my camera uses I've just been shoving what ever Class 10 SD Card I could afford into it and it works. Same on any Single Board Computer's I've messed with.
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.
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!

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.
Finally someone cleared that SD card terminology up for me. Thank you.

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!
SD Express is where the speed is at. The newest format of SD cards are being read through your PC's PCIe lanes, giving them incredible speed.
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!👍
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.
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!
Very complete information. Thanks teacher!
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.

just kidding lov ur vids
Awesome explanations, I will keep this video handy anytime I shop for SD cards. Thanks
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.
Thank you for an update to this interesting subject.
32GB SD card may be a rescue to an old netbook I have got sitting somewhere around, with only 4 GB of flash storage onboard. Finally an occasion to test desktop Android on something
Short, straightforward and informative. Much obliged.
Can't wait for the part two of this video, in which you will compare MicroSD cards. =)
We could probably do with an explanation of SLC/MLC... as well as backwards compatibility between different standards. As it turns out, 2GB cards are very expensive now because some critical legacy equipment cannot support >2GB cards... I assume as time goes on this process will continue.
For clear precise explanation of various computer standards and interfaces, your channel is my first stop! Thanks for your efforts!
-let's face it, sd cards are gonna die soon-
Mobile phones these days are starting to lose it's micro sd slot and cameras are starting to use 2.5 inch ssds
This is very true -- and one reason for the SD Card Association to set the SD Express standard in place. We're also starting to see cameras that take an M.2 SSD in a caddy.
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.
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. RUclips's algorithm sometimes helps, but is often off the mark.
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
Very thorough explanation. Doesn't feel like 20 years ago when SD came out, I remember having a few compact flash and Smart media devices at the time and wondering what would prevail. I don't like the naming convention of SD cards, it is totally convoluted, is it really necessary to say the card can maintain 10mb/s 6 different ways?
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!
I don't know why but I want a sd uc express card with 128tb right now 😁
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.
Excellent video as always. 🤗👍🏻 It explain everything so clear so you actually can remember it afterwards. 😃 Thank you! 🤗
Great Video 👍🏻
And I’m really looking forward to the Micro SD card video too 😊
Me too
Wow, even micro SD cards are now being designed to use the PCIe bus? I didn't know cell phones even had those. I'm not too familiar with mobile technology lol
SD Express cards and devices have yet to arrive on the market. But the standard is indeed now set.
Timing it’s everything. Storage 👍🏾
Agreed! Greetings my friend.
OK, I only clicked because I saw that SD cards could contain 128 terabytes and I was mind-blown. Didn't know what to do so I clicked it.
The standard for 128TB is set, the cards are yet to arrived. It is mind blowing! :)
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 :-)
1st Person: How much capacity does your smartphone has?
2nd Person: 64gb. How about yours?
1st Person: Mine has 2tb of storage...via SD Card.
Will you be making a video on Porteus Kiosk?
New to me -- and interesting. I will take a look! :)
Good grief, SD cards got complex!!!
Thank you for the video, but what a mess of labels! And so many overlapping terms...
I know. A real mess.
Chuck a 128TB SDuc in Switch, SteamDeck, handheld gaming pc and potentially have every game from every system up to the PS5/Xbox Series X in the palm of your hand.

@ExplainingComputers
Would you recommend an sdCard or an eMMC Module for Rock Pi 4 Penta Sata Hat Config?
Also do you know if Rock Pi 4 supports UHS-2 speeds?
Radxa support won't tell me that, they just recommend the eMMC Module.
I'm currently getting around 10MB/s reads and writes, on every thing even downloads. My current boot drive is a sdCard Kingston Class 10 U1. HDD file transfers also around 10MB/s. hdparm gives me normal 100MB/s speed for the SATA HDD over the hat.
Power supply is a 4-pin molex with (12@2A + 5V@2A) rated power adapter from a IDE to USB Kit i have.
Could it be the sdCard or the problem is power ?
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.
Wow! And to think 2005 tech was crazy advanced at the time. 2025 to 2050 may be really space age!
You are right. Amazing things still lie ahead.
love the illustration
so wait this is confusing...I found a 32GB MICRO SDHC CLASS 10 U3 V30 A1
class 10 is minimum 10mb/s but the U3 and V30 means its minimum 30mb/s right?
so what speeds I'm going to get? >_
U3 and V30 indeed means that the card is able to sustain a minimum write speed of 30 MB/s, and that should be the speed of your card. But this means that your card also meets (and exceeds!) the Class 10 requirement of being able to write data at 10 MB/s. So the card can bear both the U3 and Class 10 labels. But the way that this is done on SD cards is indeed confusing and crazy.
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.
Ja Chegamos no Limites Ultrapassados pelo Futuro Infinitos de 320TB ao Infinito ou Seja Dará para Gravar num Único SSD? 300 Anos de Vida de Toda a Humanidades num Único Disco Rígido ou Chipe Digital de Cristal?
Thank you. Great explaination. Almost losted in the jungle of these terms before this video.
I always thought SD stands for SanDisk
best tech explaining channel ever!
Chris, would you have any idea if "good" quality digital cameras like the Nikon D850 or the Olympus OM-D E-M1 really get a boost from UHS II seeing that they're going 4K video at 60FPS..... that's a mighty chunk of data to be flinging onto a card..... Obviously, thanks for another awesome video!!!
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.
Last year, I decided to (finally) replace my Orange Pi's micro-SD with something faster to increase its stability. Bes Buy had SanDisks on sale and I had to choose between a 130MBps C10 A1 V10 or a 95MBps U3 V30 (no A-rating). I figured it was essentially the Pi's hard-drive, so I may as well get the one with the application-rating since that's specifically what it's for but it's very confusing and frustrating that there's multiple attributes and they mix-and-match so there's no distinct "faster" or "better". 😕
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.
Hi, I appreciate if you include ADATA 64GB Premier ONE microSDXC UHS-II U3 Class 10 in your testing. I am using this card on my Jetson Nano and it seems that after a while it becomes slow. Can Jetson Nano accommodate this card?
Why would someone want a 2 tb card??
Oh yeah. Stick it in your 8k video camera- it's eaten in 3 seconds. :P
Innit. People underestimate the size of high quality data lol
Actually at true 8k 60fps with audio it takes it 6000 seconds to fill 2TB
@@FalseDev r/theydidthemath
@@AlexParkYT Yep. It takes about 312MB/s on average. Thanks for the recognition
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.
I didn't even know SD stood for secure digital 😅
This channel is the outmost helpful one ever made, thank you for satisfying my curiosity and please do not stop
The best micro sd card for SBC's video will HOPEFULLY be uploaded soon! I will be getting a Raspberry pi 4 soon and i could use the info. Thank you! Looking forward to seeing that.
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
maybe we can bridge PCI-E peripheral devices with SDXC Express bus like the vintage SDIO devices do, without going thru USB 3.1
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
I have a Nintendo Switch with a Micro SD card used to store games. I am using a 512GB card, and they have now gotten relatively cheap that I have bought a second one of the same capacity.
In comparison, I just bought a Xbox One X, the most powerful home console on the market as of writing, today, and it only had a 1TB hard drive in it. It is possible to upgrade that to 2TB, though the process is very difficult. The console will also take remote USB powered hard drives for back up purposes, normally you see these branded at 2TB at most for about twice the price of a 512GB Micro SD.
The fact that my portable Switch, which if we are really generous is one third as powerful as an Xbox One, can have half the capacity at a half the price in a format the size of a fingernail and relatively hot swappable... is pretty mind blowing. :-O
I have got to get a new SD card for my Spectrum Next..........
Wow, that is a nice new computer.
@@ExplainingComputers When I opened up the box for the first and held I became a bit emotional to be honest as daft as that may sound.
@@clangerbasher Not daft at all -- that unboxing was kind of portal back to your earlier life.
We ended magnetic (HDD, VHS, Cassette, FDD) era and started NAND-Flash era.
128TB at size of fingernail with speed up to 1GB/s.
What a time to be alive!
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 .
@@Prakhar_Choubey I know. But we can DREAM of the day when one will.
A fun fact is that I have several 16GB Transcends and smaller cheaper cards that been running 24/7 for years without problem. But my 64GB Sandisk ultra died within one year, got a warranty replacement and it too broke within one year (becomes read only). Raspberry Pi can really eat SD cards unless swapping is turned off and tmp/log etc is put on the RAM.
Last time I was here this early the Western Roman Empire still existed.
Yo! :)
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!

They both deal with different aspects of computers, doesn't really make sense to compare
It sounds very strange to be talking about using the NVMe interface and yet still not maxing out USB 3.0 let alone USB 3.1 gen 2.
Not to detract from the amazing advancements that have been made, but it does add to the confusion when people might see that a SATA SSD is faster than an NVMe SD. Manufacturers do like to be a little fuzzy when it comes to trending buzzwords.
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 :)
@@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.
With full enthusiasm for SD cards (I don't want to be a spoiler). I have already broken some micro SD cards in a very short time. I've had quite a few SSDs for a very long time and no problems.

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.
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!
