Plextor intros high-end PCIe solid-state drive

Plextor announced today the M6e solid-state drive (SSD). Unlike the standard SATA SSDs, such as the Plextor M5 Pro Xtreme (512GB), the M6e comes designed as a PCIe add-in card and requires an available PCIe slot (such as the one used by your video card) to work. Needless to say, it fits only in a desktop computer.

PCIe has much faster bus speed than SATA, and hence, the M6e is designed to offer much faster performance than even the fastest SATA SSDs. According to Plextor, it delivers the maximum sequential read/write speeds of 770/625 MBps and random read/… Read more
