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.
