14:38 "Phone and tablet manufacturers have not moved beyond UHS-I and show no signs of doings so" They are too content removing the sd card slot and overcharging for embedded storage instead 😆
@SevenCostanza Says:
If I can get an sd card in 8tb , why is my wd 20tb hard drive 50000 times bigger
@Zonker66 Says:
You do great stuff, sir.
@wilty5 Says:
How reliable are these SD cards for storing important data, photos, etc., and how often do they fail, generally
@Targetlockon Says:
I remember sd cards when they were half the capacity and double the price juet years ago
@Targetlockon Says:
insane how small we can have more than 2TB in that form factor
@rbalcarse13 Says:
Wow, I remember SD cards having only 64-256mb way back in the early 00s. Now they have Terabyte options on the market. My only complaint is the speed of file transfers.
@douglaspeale9727 Says:
Dash cams bring up several requirements that seldom have specifications from card manufacturers. The primary one being endurance. How often can the card be completely overwritten before some cells wear out and render the card useless. Also, how much power does the card use? A higher power card can generate enough heat to cause a dash cam sitting in a hot car to overheat and shut down. One thing that dash cams do that most other cameras don't is to delete old data as they are recording new data. I'm not sure the write speed specification covers erasing while writing.

The nintendo switch 2 will be needing faster speeds
@oggilein1 Says:
I know the "MNT Reform Next" hobbyist laptop will ship with an internal microsd express slot, have yet to see any other products support them
@tyboy158 Says:
I still take psychic damage whenever I see "2025 update" or the like on tech videos
@frederik188 Says:
As usual a very informative and fun to watch video. Thank you and keep up the good work.
@aoikemono6414 Says:
I have always hated the removable card industry. They can't get their act together and have ten thousand standards. I don't think there is even enough space to list all the performance standards on the card itself anymore.
@KingLarbear Says:
I wish I could watch this in 3x
@matthewmenteer5673 Says:
Having lived through several itterations of HDMI, SD, and DP I always have favored the standards that were forward thinking enough. Like my camera from 2003 will support up to 2TB storage, but SD took its sweet time. That and working for electronics retailers, confusing standards and iterations and bad standards were a bane on my existance. Even for non interface/storage stuff, HDR, Hz and just labels on a box mean absolutely nothing. You have to find trustworthy reviewers. Motion 240 might mean your tv only displays 60hz. or your TV lacks the bandwidth to support certain display modes, but i digress. Its good to see improvements, i just wish the standards would plan ahead, especially in terms of speed, and storage size. it felt like SD was launching with new incompatible tech every few years with the same form factor; while other form factors quietly and steadily improved until chased out of the market by the cheaper SD card.
@HelloKitty-x4u6d Says:
Fun fact: SD cards are called SECURE DIGITAL because the manufacturer was planning it to be the next Audio format which tailed.
@FabianWinkler Says:
I am sure, the upcoming Nintendo Switch 2 will use SD Express micro 3x1 cards for expanding the internal memory.
@truthseeker1934 Says:
1:50 I'm really proud for guessing the name of next generation of cards right. 🤣 Biggest achievement of my life fr 😢
@kunka592 Says:
All the standards being advertised were always confusing so you really cleared it up. Thanks.
@lutrueson9000 Says:
another good vid thanks, I am trying to find more robust micro SD card as i kill them around the two year point, i would like to save some money and cant find better, for context they are running 24/7 on my platform and dont have space for external drives
@gregorymccoy6797 Says:
I'm not sure about everyone else here but I've found SD cards do fail more than I would expect. Not common by any means but often enough for me to not be surprised should they fail.
@d2sfavs Says:
excellent video so much great information didnt realize how complex these cards get.thank you for sharing
@e2U Says:
What is truly disappointing isn't just that companies like these can remove SD card readers or other features from phones and tablets—it’s that we, the consumers, allow it to happen. This highlights a larger issue: the lack of a true, independent advocacy for what’s right—something that our government should be providing. Ideally, government should function as a safeguard against corporations putting profits over people’s needs, ensuring fairness and protecting consumer interests. However, the harsh reality is that we, as a society, have normalized practices like legalized bribery—rebranded as “lobbying.” This system enables corporations to exert disproportionate influence over policies that should prioritize the public’s best interests. By allowing this, we tacitly accept a framework where profit motives overshadow principles of equity and fairness. But there’s an even deeper disappointment. Many of us fail to recognize what government’s true purpose is. Contrary to the ideals we’ve been taught to believe, government isn’t always structured to protect the rights of its citizens—what I refer to as the “chattel” (us, the people). Instead, it often operates to maintain control on behalf of those at the top, creating an illusion of choice and freedom. This illusion keeps us pacified while the system ensures that those in positions of power remain insulated and secure. What’s needed now more than ever is awareness and collective action. We must recognize this imbalance of power, challenge it, and demand systems that prioritize fairness, transparency, and accountability. Only then can we begin to shift from being passive observers to active participants in shaping a system that works for everyone, not just for the few.

SD cards a junk, they physically break, lose data, there are tons of fake ones, their slow. People really need to stop using them and designing them in. USB is far better and enough bigger that it's hard to break.
@scruples671 Says:
How are the large capacity ones being faked. They are not the stating size or are they tricking the format?
@ManolVojka Says:
How ancient you are, i remember you since i was at high school!
@profsacin Says:
Great video. Thanks.
@bb1televator Says:
I’m reminded why it took me a month of investigation just to get the optimal sd card for my Nintendo switch lol. I didn’t want to over pay for speed rating that went to waste, but I also didn’t want to potentially underutilize what the internal connection was capable of
@US_Joe Says:
Great post - thank you sir. 👍👍👍👍👍💫💫💫💫💫
@JLSticePro Says:
Been working with computer systems over 30 years and I still learn something every time I watch one of your videos. Great content mate!
@ko55579 Says:
I wonder what Nintendo will do with this in the Switch 2
@Blubb5000 Says:
Great info in the video. However, I had to play the video at 2x speed. Otherwise I would have fallen asleep after the first minute.
@lyfandeth Says:
Nice thorough breakdown.
@johngalvin6352 Says:
Thanks guys another great show, full of the information we need.
@Stephen-2097 Says:
I’ve found SD cards to be one of the most versatile and reliable types of external storage for well over 20 years now. I’ve still got some Sandisk, Kingston and other bigger brand cards from the early days. Still working perfect. If you use them as per their use case, they can have a very long useful life indeed. I wish all devices included a micro SD card slot, at least.
@abunk8691 Says:
Thanks for the nice and well explained summary if the state if SD cards Chris. No matter how many times I hear the UHS naming thing on SD cards its still baffling why they used the same name of "UHS" as both a Speed Class and Bus Interface as its very confusing when buying them.
@kaisenii3821 Says:
Make a video about mobile storage types
@redknight4 Says:
there might be an update to this soon if a leak about an upcoming device is correct about it using micro sd express cards for expanded storage
@TheHomeExpert5 Says:
What's with the hair?
@stephenhargreaves9011 Says:
I wasn't going to respond on this video, as interesting as it is, but felt that I had to, following a (very) recent experience. "What", you may ask, "was that". Well, I have a dashcam in my car, that uses MIcro SD cards (it insists on class 10), and I have a completely different form factor in my camera (I forget which), and to save myself the trouble of various adapters, I bought a 7 in 1 3.5 inch internal card reader. I can't complain. I had an unused USB 2.0 header on my MB, and on the rare occasions that I upgrade my case, I insist on having front drive ports (usually for CD/DVD drives, but the one I have now has a 3.5 cutout, so all good). Until I tested with my microSD, which went straight through and was eaten by the reader. Fortunately, with the aid of something to punch it, the front panel can be popped off, and the miscreant card recovered. Unfortunately, I managed to do it a second time (doh!). I've now learned to angle the card down slightly before inserting, but it begs the question, are SD Cards the new USB. i.e. It doesn't matter how careful you are, you will never insert them the correct way on the first or second try. It's always the third go when you get it right?
@FennecTECH Says:
Well. That’s as far as the Nintendo switch goes.
@doloresdelano4656 Says:
Thank you very well explained.
@larryerb Says:
I have been ripped of with fakes.
@ericneilson1198 Says:
Where is the micro sd card reader to connect to a SATA motherboard slot? No, external readers are not welcome.
@dallesamllhals9161 Says:
Hmm, so if just SanDisk SDs: Ultra < Extreme < Extreme PRO. Right, internet?
@davidbwa Says:
There are more SD options than I realized. Thank you for a calm, clear, informative video without "jazzing it up" with a bunch of thumping background music and jerky, eyesore video transitions.
@pgtips73 Says:
Good grief! How complex is this?! There's a rumour the Nintendo Switch 2 will be using SD Express cards - which I'd never heard of - and low and behold, here's Mr Explaining Computers with a video right out of the gate for 2025! Amazing work.
@derrikarenal3308 Says:
This: Overachiever-level research and polished presentation.
@breznewman Says:
Sir, could you please add an .DE affil link, so we in the rest of EU, could support your very good and informative work? ;) (we need to pay a lot of taxes, cause of the brexit when we shop, or change manually the link to .de ourself, and then your affil link does not work anymore?)
@meikala2114 Says:
Fairphones still have a micro SD slot on their flagship models
