Thanks for answering!
I have a 100 euro coupon to a company, and the "old" SM951 128Gb is down to exactly 100 euro now. The NVMe version cost 115 euro, and unfortunately I can't add any money, otherwise I would go a for a pro or a 256Gb version.
I only need it as a boot drive, would it work, on a Asrock X99 Itx board? Would it be fast?
Already got two 850 Evo 500Gb in raid 0 and a single 850 Pro 1Tb - all for storage and games.
