Frequently Asked Questions

Will the heatsink fit in my PC or my PS5?

It is a standard M.2 2280 drive with a factory heatsink. Measure clearance under your GPU or CPU cooler first, and check the current listing for exact heatsink dimensions before ordering.

How fast is the WD_BLACK SN850X 1TB really?

Sandisk rates it at up to 7,300 MB/s sequential read and up to 6,300 MB/s sequential write on the 1TB through 4TB models, which requires a PCIe Gen4 x4 M.2 slot.

Do I need the WD_BLACK Dashboard software?

Only for extras. The drive works as plain storage without it. The Dashboard, which is Windows only, adds drive health monitoring, RGB customization, and Game Mode 2.0.

Is TLC NAND better than QLC for gaming?

This drive uses Sandisk TLC 3D NAND, which generally sustains write speeds longer and rates for more endurance than QLC. That matters when installing or patching large games.

Is 1TB enough, or should I size up?

1TB holds roughly eight to twelve current AAA installs. The SN850X family scales to 8TB, and the heatsink version is offered in 1TB and 2TB, so 2TB is the next step up.
