Hi. I have been given a Corsair MP400 NVMe PCle Gen3 x4 M.2 SSD (1 TB). I am told I can buy an enclosure for it, to use it as an external drive, e.g. to back up my new laptop OS. But I know nothing of these SSDs, and cannot find a case/enclosure that matches exactly. Most of the ones on Amazon are Gen2, not Gen 3x4 - does this make a difference? Any suggestions?
