Had a similar experience with a friend's "10 TB" SSD. After I tested it with f3 and confirmed it was fake, I opened the case and found a 64 GB microSD card and an adapter/faker board.

"10 TB"? Why did you even need to open it??
- thedanbob 2y ago
  Well, at first it only showed up as 2 TB, which was at least possible though unlikely. But f3 indicated it was faking 10, at which point I realized it was presenting several additional partitions that were so corrupted the OS wasn’t even making them available to mount. After that I opened it just to see what was inside.

    I suspect LorenPechtel's terse question implies that a 10 TB drive would weigh appreciably more with real hardware than a microSD card.

      SSDs can be pretty lightweight. And also sometimes the fake ones have a piece of metal or even a rock glued to the inside of the thing to make it feel heavier.

      Weight doesn't even have to be accounted for. There's simply no technological or marketing reason to manufacture a 10TB SSD. An odd size like that is already a massive red flag.

        They do make 10 TB+ SSDs: https://www.allhdd.com/kioxia-kcmyxrug15t3-15.36tb-ssd https://www.allhdd.com/kioxia-kcmyxrug15t3-15.36tb-ssd Infact, Kioxia's enterprise line goes up to 30 TB/drive.

        You linked a 15.3TB drive which doesn't dispute his point. 10TB has never been a manufactured SSD size that I'm aware of. In the enterprise we've got approximately 960GB, 1.92TB, 3.84TB, 7.6TB, 15.3TB, 32TB. 10 is skipped entirely, unless you can provide an example of any reputable manufacturer producing one. Consumer drives don't follow that exactly, but consumer SSDs also don't hit 10TB+.

        Exactly. I didn't say 10TB was too big, I said it was an odd size. There's no easy way to get close to 10TB when using components that are sized by powers of two, plus or minus varying amounts of overprovisioning depending on market segment, and GB vs GiB differences. ~8TB SSDs are common in consumer and enterprise markets. 16TB drives that expose 15.36TB usable space are common in enterprise, and 12.8TB usable space from ~16TB raw flash isn't unheard of. 10TB usable space isn't theoretically impossible, but it simply wouldn't make sense.

        > There's no easy way to get close to 10TB when using components that are sized by powers of two... I expect you can get any usable capacity you like by reserving some subset of the flash for onboard spare/scratch space. I think I remember long ago Anandtech doing some benchmarking the changing performance of some drives as they adjusted the size of this "housekeeping" section of the drive. No clue if it's adjustable on every drive, but it sure was on the ones they were testing.

      No, I'm saying that flash devices are pretty close to powers of two because that's how the chips come. I would presume any solid state device purporting to be 10TB would be fake unless I had clear evidence otherwise.
