Our take on the WD_BLACK SN850X NVMe SSD 4 TB

The WD_BLACK SN850X is a PCIe 4.0 NVMe SSD in the M.2 2280 form factor, built for gaming PCs and the PlayStation 5. The 4 TB version holds a large game library and keeps sequential reads near the top of the PCIe 4.0 class. It is a strong pick for players and creators who want fast load times without moving to PCIe 5.0, and it competes closely with the Samsung 990 Pro and Crucial P5 Plus. Owners rate it highly for speed and reliability.

Questions and answers

Is the SN850X fast enough for a PlayStation 5?
Yes. It is a PCIe 4.0 NVMe drive that meets Sony's requirements. A heatsink version is the safer choice for the console's slot.
Do I need a heatsink?
For sustained writes and tight cases, yes. The drive runs warm under load, and a heatsink keeps temperatures in check.
How does it compare with the Samsung 990 Pro?
Both are top-tier PCIe 4.0 drives. The 990 Pro edges ahead in some benchmarks; the SN850X is close in real-world use and often favored for gaming.
Will it work in my laptop?
Only if the laptop has an M.2 2280 PCIe slot. Check the slot length and clearance before buying, since many thin laptops use shorter drives.
What is in the box?
The drive itself. Screws and heatsinks are not included unless you buy a heatsink bundle.
Is 4 TB overkill?
Only if you keep a large game or media library. For a boot drive with a few games, a smaller capacity is enough.
