Western Digital is bringing 3D NAND to their high-end consumer SSD family with the launch today of two new NVMe SSDs featuring SanDisk's 64-layer 3D TLC NAND flash memory. As with the SATA SSDs that first brought 3D NAND to their consumer portfolio, Western Digital is releasing the same drive under both their WD and SanDisk brands. Under the stickers, the hardware is identical.

The names are recycled and familiar: the WD Black and SanDisk Extreme PRO. The first WD Black SSD was Western Digital's first consumer NVMe product. It used a Marvell controller and 15nm planar TLC NAND, and ended up near the bottom of the performance rankings for NVMe SSDs, with no appreciable performance advantage over SATA SSDs for heavier workloads. The SanDisk Extreme PRO name hasn't been used on an internal SSD for quite a while, but it carries a strong legacy: the original SanDisk Extreme PRO was a top-tier SATA SSD with MLC NAND and was competitive with the Samsung 850 PRO. The SATA SanDisk Extreme PRO hit the market right before the 850 PRO and was the first consumer SSD to carry a 10-year warranty, forcing Samsung to follow suit with the 850 PRO.
