What this drive is

The WD_BLACK SN850X is a 2TB internal SSD built on PCI-Express 4.0 x4 with NVMe protocol and a fitted heatsink. It uses 3D NAND TLC memory and 2GB DRAM cache to serve gaming PCs, workstations and PlayStation 5 consoles that need fast, sustained storage.

Capacity and headroom

Two terabytes hold many large titles, each often exceeding 200GB, so you can keep several installed without constant shuffling. The 1200TB endurance rating and 1.75M hour MTTF give ample write headroom for heavy daily use before wear becomes a concern.

Thermals, noise and power

The integrated heatsink manages heat during extended high-speed transfers, helping the controller maintain its 7300 MBps read and 6600 MBps write peaks. With no moving parts the drive runs silently, and Adaptive Thermal Management adjusts throttling to keep temperatures in check under load.

Questions about this item

Will the WD_BLACK SN850X 2TB with heatsink work in a motherboard that only supports PCIe 3.0?

The drive uses a PCIe 4.0 x4 interface and will operate in a PCIe 3.0 slot at reduced speeds, limited to the slot's maximum bandwidth.

How can I verify the drive is delivering its rated 7300 MB/s sequential read and 1200000 IOPS random read after installation?

Run a benchmark such as CrystalDiskMark on Windows and compare the results to the rated 7300 MB/s sequential read and 1200000 IOPS random read figures.

Does the WDS200T2XHE retail box include a mounting screw for the M.2 2280 slot, or must I buy one separately?

The box contains the SSD with the pre-attached heatsink; a mounting screw is typically supplied with the motherboard, not the drive.
