Western Digital launched a few new NVMe SSDs at Mobile World Congress today:

To the left we have the WD PC SN720, a PCIe 3.0 x4 NVMe SSD boasting speeds of up to 3.4GB/s and IOPS up to 500k. Available capacities are 1TB, 512GB, and 256GB. To the right we have the WD PC SN520, a more power efficient variant running on half of the PCIe lanes, and with specs coming in at roughly half of its faster brother. Capacities are also cut in half, with the range dropping to 512GB, 256GB, and 128GB. Interestingly, all capacities are available in three M.2 form factors (2280, 2242, and 2230).

We don't have a specific part number for the controller, but WD told us they are manufactured on a 28nm process, employ 8 NAND channels, and use DDR4 RAM (not DRAMless). The controller is optimized for interfacing with WD (/Toshiba) BiCS NAND flash, meaning these SSDs should prove to be a well integrated solution.

Press blast from WD appears after the break.
