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.
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.
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.
