Our take on the WD Black SN850X 1TB M.2 PCIe 4.0 NVMe

The WD Black SN850X is a PCIe 4.0 x4 NVMe M.2 internal SSD built for gaming PCs and fast workstations. The 1TB model is rated up to 7,300 MB/s sequential read and 6,300 MB/s write, with 600 TBW endurance and high random IOPS. It competes with drives like the Samsung 990 Pro and Crucial P5 Plus on speed, and its optional gaming software and long endurance make it a strong pick for game libraries and large file work. It is a heatsink-free drive, so a motherboard M.2 heatsink or aftermarket cooler is worth having.

Questions and answers

Is the SN850X worth it over a cheaper PCIe 3.0 drive?
Yes if your board has a PCIe 4.0 M.2 slot. The SN850X roughly doubles sequential speeds over PCIe 3.0 drives and loads games faster.
Does it come with a heatsink?
No. This is the bare drive, so use your motherboard's M.2 heatsink or add one for sustained heavy writes.
Will it work in a PS5?
It fits the PS5 M.2 slot, but Sony requires a heatsink for console use. This version has none, so add a compatible one.
How does it compare with the SN850?
The SN850X is the newer revision with higher rated speeds and updated firmware and software features. Both are PCIe 4.0 drives.
What is the endurance rating?
600 TBW for the 1TB model, which is high for this capacity and fine for years of normal gaming and work use.
Is 1TB enough for a gaming PC?
It holds roughly 10 to 15 large modern games. Many buyers pair it with a second drive for a bigger library.
