Western Digital has announced the WD Black PCIe SSD, their first PCIe SSD for the consumer market. While the WD Green and WD Blue SSDs introduced last fall were relatively minor updates to existing SanDisk products, the WD Black is an all-new product. The WD Black is aimed at the cheaper half of the M.2 PCIe SSD market rather than competing for the highest performance: it will be available in 256GB and 512GB capacities for $109 and $199.99 respectively, making it cheaper than any currently available M.2 PCIe SSD except the Intel 600p. The WD Black most likely uses the Marvell 88SS1093 controller and 15nm TLC NAND, a combination that will also be found in Plextor's upcoming M8Se (albeit with different firmware).
