KitGuru tried the Plextor M6e Black Edition PCIe 256GB
A quote from the article:
Today we look at the Plextor M6e Black Edition. This SSD product supports PCI Express Gen 2 x 2 and potentially delivers more performance than a simple SATA 3 capable Solid State Drive. Rated sequential speeds of the Plextor M6e Black Edition are said to hit 770MB/s. It uses the latest Marvell 88SS9183 controller alongside Toshiba synchronous Toggle NAND flash memory.Plextor M6e Black Edition PCIe 256GB Review @ KitGuru
