@@endergamer.mp4 unfortunately there are very few good android tablets, and what is available I would describe as overpriced compared to an ipad (I have a new pixel in my pocket and have used android since 2009 - literally 95% of android tablets are ewaste and I've had a few)
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!
Yeah same, it said "232" next to his name and I'd just expected a "K" after it 😂 this channel has the identity of someone who's been uploading for at least five years.
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! 💾📈😁
That speed rating system is exactly how they do it with CF cards. Which is how you end up with like 1066x speed CF cards. It's exactly the same thing as old CD-ROM speeds so a 100x CF card is twice as fast as a 52x CD-ROM drive. They've only really started moving away from this system recently.
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!
@@rodrigotudancafernandez17 So it's not just me who misread it like that?... 🙃 (That said, I come from a place that's known for its prototypes not _always_ working out as expected... 🤖🇬🇧💥😇)
When he came to that at 02:58, the first thing I thought was: _This seems _*_crazy_*_ in 2024...But just imagine how _*_small_*_ it'll seem in _*_2054_*_ !_ 😳 (I'm not exactly kidding, either. When I bought my first SD card - A 2GB one - In 2006, I thought I would never ever need a card bigger than that. Almost 20 years later and I'm routinely filling up 500GB devices without even realising it! 😇)
@@lukeumhoefer What I have to say here might shock you even more than that: My first thumb drive (Bought secondhand in 2003) was 32 *MB* and cost me (IIRC) about £10,- incl. postage. At that cost/MB your 8GB drive works out to more than *£2.500,-!* 😳😳😳 Mind you, technology always reduces in price as economies of scale increase. The last one I bought (I get through a lot of flash drives! 🙃) was 256GB and cost just £15,- 🙂
@@lukeumhoefer What's crazy to me is how capacities of things like SD cards and little USB drives continue to go up rapidly, while the amount of storage in a typical laptop has stagnated. The first laptop I ever bought cost me about $600 in 2011, and came with a 500 GB spinning-disk hard drive. These days, the typical size of a laptop SSD is somehow still about 512 GB. Granted, that's a 512 GB NVMe SSD, as opposed to a 500 GB mechanical hard drive and so it's **much** faster, but still the size has not really gone up despite the fact that we have 512 GB SD cards now!
why is it insane? The theoretical maximum is only limited by how many bytes can be allocated for partition size, it is not particularly computationally expensive to make it possible for it to support 128T. If anything, I think it's actually kinda small. Also, I don't understand people here who are saying that this is ever going to seem small in 2054. Perhaps if you are trying to record raw video in ungodly high resolutions it might be, or if you are trying to back up unoptimized media, but for most users the current limits are already far more than enough. My laptop has a 500G SSD, and sort of filling it up by trying to back up high resolution movies, gazillions of books or bloated modern games, I genuinely cannot image how I would fill it up
I imagine Bono would be demanding heavy royalties if there was a U2 class. From what I understand, this has been a problem between that group and any German city with more than one underground line for _years_ now... 🧑🎤🇩🇪🚇😉
You are one of the only exceptions to RU-vid’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
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.
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.
I've been involved in technology for over two decades, and this video is the first time I've ever heard the A1/A2 symbols being explained. Thanks to this man, I now *know* which cards I need to put in my phone to successfully expand the storage on my Android devices! 💾📈❤👍
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 🙌
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
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 !
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
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.
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.
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 RU-vidrs 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!
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. 😂
💡 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)
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.
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.
* 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...
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!
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!
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.
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!
Thanks for your feedback! I actually did invest in a C-stand after seeing how shaky the overhead looked in the edit, lol, hopefully you won't notice any problems in the future!!
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.
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.
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.
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.
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.)
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.
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
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 ;------)
