This is the cream of the crop when it comesa to pssd's. The Skhynix 2TB Beetle X31 in grey. It has been lightly used and Crystal Disk Info lists it's SMARt data at 100% life left.

This pssd comes with a clear case and 2 data cables. It runs up to 1gb/s in a usb 3.2 gen 1 port or higher. This is the only one I've got so if you want it, you had better act fast.

This is the only pssd that I know of that has a dram cache. You can get an ssd with a dram cache and put it in an enclosure true but this one is made portable not do it yourself.
