Hi. I was given a Corsair MP400 NVMe PCle Gen3x4 M.2 SSD, 1TB. Apparently I should be able to buy a case/enclosure for it, and use it as an external drive. But I have not so far found a case that is for NVMe PCle Gen3x4 M.2 etc. I haven't got a clue really - what specs should I be looking for? Thanks.
