My top recommendation is still the Crucial P2 1TB 3D M.2 SSD, a drive that makes it to the top of the list because of its affordable price, excellent performance, and high reliability.
Crucial is phasing out its wildly popular MX500 ... and it only claims sequential read speeds of up to 560MB/s. Even a last-gen M.2 SSD like the Samsung 990 Pro can reach speeds of up to 7,450MB ...
