I bought a 2242 size m.2 SSD to use as lvm cache for an external DAS I'm working with. The drive is supposed to be 64GB, but when I pulled it up in gparted I found the below. (I created the partition to see what would happen.) If my calculations are correct, this drive is acting like a 1TB drive instead of a 64GB drive.

If my calculator is correct, a 64GB drive should be 59.6 GiB instead of 931.5 GiB.

So, would you trust this drive?

There are SSD and usb stick drives with a fake size programmed into it. There are scams who sell higher capacity, but delivering lower capacity. Looking in file browser (or other tools), it still looks like 1 TB. But as soon as you fill the real 64 GB, the rest of the data is written into the void = data loss. So from the looks like this drive was originally a fake drive. And whoever sells it to you probably knows it and tries to sell it correctly as a 64 GB (or maybe the original size is even different), after getting scammed maybe?

Whatever the original story is, this drive looks fishy, acts fishy and is probably a fish. I don't know how much you spend on this, but I would not use it, throw it away. Please don't give or sell it to someone else, or keep it as an evidence. If possible, report the person who sold it to you.
