I would watch what you buy with cheapo SSD drives, many have fake chips and faked to say to mis-report the size.
Had one knocking about round here a week or so ago, once you re-partition the volume, it reports 8meg or less, was supposed to be 8gb. You write to them but overwrite themselves to appear valid but once you move the drive to another computer the files won't read.
Luckily the guy who bought it managed to get a refund.
You have been warned!
