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?
Yeah, I'm quite aware of a lot of the junk on Amazon -- and I normally would stick to a well known brand like Samsung, WD, or Crucial... But there were no listings for m.2 SSD's in the 32-64G range. At first I ordered a "Kingdata" drive (an obvious play on Kingston), but later I saw a listing for a drive from Transcend -- which I recalled from my IT days, and a quick check of their website confirmed they were the company I was thinking of.
So, this is why I am fairly certain that this is some kind of labeling / packaging mistake. Transcend is reasonably well-known, and afaik aren't scammers.
And, to top it off, I ran some additional tests on the drive... And for what it is, it is performing exactly how I would have expected: 420MB/s read/write, with 0.1msec access times -- with extreme consistency. (Given that this is installed on a PCIE adapter that only has 1 lane available.)
