The Western Digital Blue 3D is a solid-state drive in the 2.5" form factor, launched on May 29th, 2017. It is available in capacities ranging from 250 GB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Western Digital Blue 3D interfaces using a SATA 6 Gbps connection. The SSD controller is the 88SS1074 Dean from Marvell. Western Digital has installed 64-layer TLC NAND flash on the Blue 3D, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly.

At its launch, the SSD was priced at 560 USD. The warranty length is set to five years, which is an excellent warranty period. Western Digital guarantees an endurance rating of 500 TBW, a relatively low value compared to other SSDs.
