Frequently Asked Questions

How fast is the WD_BLACK SN850X 1TB?

It is rated for sequential reads up to 7,300 MB/s and sequential writes up to 6,300 MB/s. The 7,300 MB/s read figure applies to the 1TB through 4TB capacities.

Will it fit my motherboard?

It is an M.2 2280 internal SSD, the standard 22mm x 80mm size used by nearly all desktop motherboards and most compact builds. Confirm your board has a free M.2 slot.

Do I need a PCIe Gen4 slot?

To reach the rated 7,300 MB/s you need a Gen4-capable M.2 slot. It will still work in a Gen3 slot, but sequential throughput will be capped by that interface.

Is 1TB enough for a gaming PC?

1TB covers Windows plus roughly six to ten modern titles depending on install size. The SN850X family goes up to 8TB if you want more games staged at once.

Is this drive still current?

The listing states it has been replaced by the SanDisk Optimus GX PRO 850X NVMe SSD. Compare both listings for current pricing and specs before you buy.
