Our take on the WD_BLACK 1TB SN850X NVMe Internal Gaming SSD

The WD_BLACK SN850X is a PCIe 4.0 NVMe M.2 SSD aimed at gamers, with sequential reads up to 7,300 MB/s on the 1TB model. It uses a WD in-house controller with 112-layer TLC NAND and an optional Game Mode 2.0 in the WD dashboard that tunes read behavior for game loading. Against rivals like the Samsung 990 Pro and Crucial P5 Plus it trades blows on speed and runs without a heatsink unless you pick the version that has one. Reviewers rate it among the fastest PCIe 4.0 drives for load times and large file transfers, though it runs warm under sustained writes and its peak speeds need a PCIe 4.0 slot.

Questions and answers

Is the SN850X worth it over cheaper PCIe 4.0 SSDs?
It sits near the top of PCIe 4.0 for load times and sustained writes. If you mostly game and move large files, the gap over budget drives is real but small in everyday use.
Does it need a heatsink?
The bare drive works in most desktop builds with decent airflow. For sustained writes, tight cases or a PS5, pick the heatsink version or add a motherboard heatsink.
Will it reach 7,300 MB/s in my PC?
Only in a PCIe 4.0 M.2 slot. In a PCIe 3.0 slot it runs at PCIe 3.0 speeds, roughly half the rated sequential read.
Is it compatible with the PS5?
Yes, in the heatsink version, which fits the PS5 expansion bay. The bare drive needs a heatsink to meet Sony's requirements.
What's in the box?
The M.2 SSD itself, plus mounting screw and quick start guide. The heatsink version adds the attached heatsink.
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 and power efficiency; the SN850X is close in games and often the better value.
Where is the WD_BLACK 1TB SN850X NVMe Internal Gaming SSD cheapest?
At Nex Phone, for $156.26, 61% under what the other stores charge, as of our latest check.
