Question: what is the difference between samsung pro and evo?
Answer: The key difference between the Pro and the Evo is the type of NAND used: the Pro uses MLC V-NAND, while the Evo uses the cheaper and more tightly packed TLC V-NAND. ... Random read performance on the 256GB 960 Evo is 330K IOPS, with write speeds of up to 300K IOPS. Larger capacities bump that to 380K IOPS and 360k IOPS.
