The 970 PRO makes use of 2-bit MLC V-NAND, along with the new and refined Phoenix controller, claiming speeds up to 3500MB/s read and 2700MB/s write. 500,000 IOPS in random read and write is also quoted. These numbers, on paper at least, make the 970 PRO around 30% faster in sequential performance and over 50% faster in random access than the previous generation.
