Samsung's EVO series SSDs are known for delivering performance, reliability and storage capacity at a reasonable price and the 870 EVO is no exception. Designed and built entirely in-house, this new 2.5-inch SATA SSD is powered by the same MKX "Metis" controller found in the 870 QVO and is available with up to 4TB of Samsung's latest 3-bit MLC V-NAND flash. Combine this with a large DRAM cache and the company's Intelligent TurboWrite technology and you have one of the better performing SATA SSDs on the market today. In our tests, the 1TB version of the 870 EVO was able to read at speeds as high as 564 MB/s and write at speeds in excess of 530 MB/s. The drive also did very well in our random write tests, producing more than 92,000 IOPS at low queue depths.
