At first glance, the M9P Plus series may seem like nothing more than the M9Pe with a fresh coat of paint. However, Plextor's engineers have made a number of changes under the hood. Along with new and improved technologies like PlexNitro II, TrueProtect II and SmartProtect, the M9P Plus is powered by Marvell's 88SS1092 controller and is available with up to 1TB of Toshiba's 96-layer BiCS4 3D NAND flash. Combine this with a PCIe Gen3 x4 NVMe 1.3 interface and you have a reasonably priced drive capable of delivering more than six times the performance of your average SATA 6Gb/s SSD. In our sequential read and write tests, the 512GB version of the M9PY Plus was able to read at speeds as high as 3,465 MB/s and write at speeds in excess of 2,213 MB/s. The drive also did very well in our random write tests, producing nearly 200,000 IOPS at low queue depths.
