Samsung SSD 850 EVO M.2 250GB Solid State Drive Review @ CDRLabs.com

"With the 850 EVO M.2, Samsung has proven once again that good things do come in small packages. Designed and built entirely in-house, this diminutive drive is powered by Samsung's energy-efficient MGX controller and is available with up to 500GB of the company's 3-bit 3D V-NAND flash. It also comes equipped with Samsung's innovative TurboWrite technology which uses a high speed buffer to maximize a user's everyday computing experience. Like its full size counterpart, the 850 EVO M.2 performed relatively well throughout most of our tests. In our sequential read and write tests, the 250GB version of the drive was able to read at speeds as high as 552 MB/s and write at speeds in excess of 471 MB/s. It also did very well in our random write tests, producing more than 75,000 IOPS at low queue depths."
