WD_BLACK SN850 1TB M.2 2280 PCIe Gen4 NVMe Gaming SSD up to 7000 MB/s read speed

Product Information

The 970 PRO is old enough that newer, faster TLC NAND is catching up even in tests where MLC used to be a major advantage—and of course the latest and greatest TLC drives with PCIe 4. Western Digital doesn't give us detailed performance specifications the way Samsung does, but the basic specifications make it clear that this drive is aimed at the very top: sequential reads up to 7GB/s are pushing the limits of the PCIe 4. NVMe SSD Review: Top-Tier Storage for Gamers and Pros (Updated) With WD’s Black SN850 now in the lab, we will see if it really is ideal for those looking for fast, consistent storage.

Now after learning some very valuable lessons from the SN700 and its minor refresh SN750, WD is back with the WD Black SN850, the first real hardware upgrade to the Black product line in over two years. However, the 4TB model doesn’t have a heatsink option, and WD doesn’t recommend using the SN850X in that console without one. Instead, holes have been cut through the sides allowing air to circulate and significantly increasing the surface area. Outlets and voltage differ internationally and this product may require an adapter or converter for use in your destination.

We took a deep-dive look at Microsoft's DirectStorage feature in our recent Phison I/O+ firmware preview. The Intel SSD 670p is more of a low-end drive since it uses QLC NAND, but it's based on a very new generation of 3D NAND and a brand new controller from Silicon Motion which help it achieve great peak performance when using its SLC cache. It has to match 600TB and 1200TB values for the 1TB and 2TB drives with its SN850 brothers but now includes the whopping 2400TB capability of the 4TB drive. WD supports the Black SN850 with WD Dashboard, the company’s SSD toolbox that includes analysis tools, a firmware updater, and RGB lighting control on the heatsink model.
