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?

    As long as whatever software you’re using can handle a cache failure, I can’t see why not. I’d put my ~/.cache on there no problem.

      Meant to comment on this earlier… I’m implementing an LVM cache – which is filesystem / device level caching. Having a failure with something at this level could mean corrupting a 42TB storage device. This would be a far cry from losing an application level set of cache files…

      That’s why I am being a lot more cautious about this drive. A failure here could be non-recoverable.
