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?

If you can return it, return it.

If not, nuke it: overwrite the first MB or so with dd. You could also tell gparted to create a new partition table. Then, reboot, and try again to see what it reports.

And no, I would not trust it to do crucial stuff in any case. And 64GB isn't much anyhow.
