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?

    Okay - wild… The results of f3probe:

    Good news: The device `/dev/sda’ is the real thing

    Device geometry: Usable size: 931.51 GB (1953525168 blocks) Announced size: 931.51 GB (1953525168 blocks) Module: 1.00 TB (2^40 Bytes) Approximate cache size: 0.00 Byte (0 blocks), need-reset=no Physical block size: 512.00 Byte (2^9 Bytes)

    Probe time: 16.12s

    Oops - misstated something before. This is an MLC NAND drive, the cache is supposed to be DDR4 DRAM. I suspect, however, this is a mis-labeled drive…
