For Plextor, the M5 Pro SSD is an outstanding achievement, not only in regards to performance, but the technologies it brings together. Designed with prosumer and business users in mind, the M5 Pro combines Marvell's new 88SS9187 controller with Toshiba's 19nm Toggle Mode NAND flash to deliver some of the best all around performance we've seen. In our sequential read and write tests, the PX-256M5P was able to read at speeds as high as 547 MB/s and write at speeds in excess of 440 MB/s. It also did reasonably well our random write tests, producing nearly 67,000 IOPS at low queue depths. Increasing the queue depth did lead to better results. However, the PX-256M5P still had a hard time keeping up with the OCZ Vertex 4.
