Editor Notes
Overview
The WD Blue 3D NAND was Western Digital's mainstream SATA SSD from 2017, built on a Marvell 88SS1074 controller and WD/SanDisk's 64-layer 3D TLC NAND. At launch it competed directly with the Crucial MX500 and Samsung 860 EVO at similar prices, with sequential speeds of 560/530 MB/s at 500GB and above.
The drive shipped in both 2.5" and M.2 SATA (2280) form factors with identical performance. The M.2 SATA variant (WDS*2B0B suffix) is for systems with M.2 slots wired for SATA rather than PCIe. The 3-year warranty was shorter than the 5-year terms offered by Samsung and Crucial in the same class.
It was succeeded by the WD Blue SA510 in 2022.

“We have nothing negative to say about the WD Blue 3D. Okay, the label is boring, which isn't trivial if you're building your own PC and want to show off all your hardware finery through the tempered-glass, LED-lit side of your case. But it's fast, affordable, and available in up to 2TB capacities, and we're impressed with whatever trick Sandisk/WD used to eliminate the MLC/TLC performance gap.”

“The Western Digital Blue 3D and SanDisk Ultra 3D are exactly what the market needs to see from next-generation 3D TLC technology.”

“Compared to the competing drives on the market today, the new WD Blue 3D NAND and SanDisk Ultra 3D have the performance that is expected of a mainstream SATA SSD. On most real-world workloads, there's no noticeable performance difference between the Ultra 3D and the Samsung 850 EVO.”
