Know before you buy
Yes, this drive meets all of Sony's requirements for PS5 storage expansion. Its M.2 2280 form factor and PCIe Gen4 speeds ensure it will work seamlessly with your console.
Yes, the SN850X is backward compatible with PCIe Gen3 slots. However, you will be limited to the maximum speed of the Gen3 interface, so you won't experience the full 7300MB/s performance.
This specific model does not come with a pre-installed heatsink. If your motherboard does not have its own integrated M.2 heatsink, we recommend adding one to ensure the drive maintains peak performance during long gaming sessions.
TBW, or Terabytes Written, measures the total amount of data you can write to the drive before it reaches its expected wear limit. For most gamers and power users, 600 TB is more than enough to last well beyond the 5-year warranty period.
Absolutely. With high random IOPS performance and fast sequential read/write speeds, this drive is well-suited for demanding tasks like 4K video editing, large file transfers, and running resource-heavy applications.
