Would You Trust This? (infosec.pub)

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 want to test it yourself, you could use a tool like f3:

f3 is a simple tool that tests flash cards capacity and performance to see if they live up to claimed specifications. It fills the device with pseudorandom data and then checks if it returns the same on reading.
