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.

It seems to me people are just foolish and buy without checking and that's why they get upset. I really do see them buying from the $1 guy and then screaming how they got scammed by Aliexpress.

@@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 .

Once again, a brilliant vid, Christopher! And very timely one, indeed. For last three months, we have been moving data storage (office, home, sbc, smartphones) to faster media and both your previous vid and, of course, this one are very good summaries of the standards lineup. I firmly believe, this vid will be very useful to many people thinking of upgrading data transfer rates. p.s.: an idea for next storage-related vid: add reliability of media (number of writes, water-protection, guarranteed terms of operation etc) to your tests/reviews of sd/ssd. Thank you! And do have a great week!

Thank you for this. The one question I had was answered in the final seconds of your presentation. I'm currently using an SSD for my Raspberry Pi 3B+. It works without an SD Card at all. Simply use Etcher to write the Raspbian image to a 2.5" SSD (or HDD) (you have to tell Etcher that you are willing to do dangerous things, and first extract the image from a ZIP file). Remove the SD Card from the Pi and boot from the external drive. It is that simple. There is no official external drive booting yet for a Pi 4. I keep hearing that using an SD Card for an operating system puts too much stress on an SD card, which has a limited number of read/write cycles, and they can quickly wear out. I have never had this problem. I hope you will address this in your SD card comparison video. Thanks again for this useful video.
