I have acquired a few M.2 drives as they sell for my next build. Can I use some of those on my 2013 build on an expansion card, and attain NVMe speeds? I do have a GTX780 in first 16x slot, and speccy says A2 slot is in use, but nothing in there. So I thought I could put an expansion card and say a WD black 512 or samsung 950 pro in there to be a boot drive, etc. Is it wishfull thinking, or can I get the full NVMe usage this way? Thank you, Larry T. Card I am looking at is ASUS Hyper M.2 X 16 V@.
