Frequently Asked Questions
Q: Is the WD_BLACK SN850X NVMe SSD compatible with the PS5?
A: Yes, the WD_BLACK SN850X M.2 2280 NVMe SSD is compatible with the PS5's M.2 expansion slot. Please note that Sony recommends using a heatsink with your PS5 M.2 SSD — a heatsink is not included with this drive and would need to be purchased separately.
Q: What is the difference between the 1TB and 2TB versions of the SN850X?
A: Both capacities use PCIe Gen4 x4 NVMe and achieve the same peak sequential read speed of 7,300 MB/s. The 2TB model offers a slightly higher sequential write speed (6,600 MB/s vs. 6,300 MB/s) and higher random read IOPS (1,200K vs. 800K), along with a larger 2GB cache (vs. 1GB). Choose 2TB if you need more space or higher sustained write performance.
Q: Does the WD SN850X NVMe SSD come with a heatsink?
A: No, this listing is for the standard non-heatsink version of the WD_BLACK SN850X. It fits into standard M.2 2280 slots in desktops, laptops, and the PS5 without obstruction. If your use case requires active cooling, a compatible third-party heatsink can be added separately.
Q: What PCIe version does my system need to use this SSD?
A: The SN850X is designed for PCIe Gen4 x4 slots to achieve its maximum rated speeds. It is backward compatible with PCIe Gen3 slots, but speeds will be limited to Gen3 bandwidth in that configuration.
