WD_BLACK SN850X 4TB M.2 NVMe SSD

The WD_BLACK SN850X 4 TB (WDS400T2X0E) is a PCIe 4.0 x4 NVMe M.2 2280 SSD aimed at gaming and performance desktops, built on 112-layer TLC NAND with an in-house Western Digital controller and DRAM cache. It is rated at 7,300 MB/s sequential read, 6,600 MB/s sequential write, 1,200K random read IOPS and 1,100K random write IOPS, with 2,400 TB written endurance and a five-year limited warranty. A heatsink version (WDS400T2XHE) is offered for consoles and open-air builds.

PC retailers and system integrators carry the SN850X as the main alternative to the Samsung 990 PRO in the 4 TB class; both drives sit at the PCIe 4.0 ceiling and their endurance ratings are identical, so stocking decisions usually come down to availability and brand mix. The drive supports Game Mode 2.0 in the WD_BLACK Dashboard, which preloads game assets, and is a common choice for PlayStation 5 expansion. Corporate buyers should note that the SN850X is a consumer-warranty product and that WD also sells it in 1 TB, 2 TB and 8 TB capacities under separate part numbers.

InTechnologies FZCO supplies WD_BLACK drives to resellers through licensed partners that issue the contract and invoice. InTechnologies sources from Western Digital authorised distribution and verified channel stock, consolidates in Dubai Airport Freezone and ships DDP or DDU.
