Know before you buy
This drive uses the M.2 2280 form factor, which is the standard size for most modern gaming laptops and desktop motherboards. Ensure your device has an available M.2 slot that supports PCIe Gen4 NVMe technology.
If you are installing this in a desktop PC with good airflow, the heatsink is optional but recommended for maintaining peak speeds during long, intense gaming sessions. If you are installing it in a laptop or a motherboard that already has built-in M.2 heat shields, the heatsink version may be too bulky to fit.
Yes, the SN850X meets the performance requirements for the PlayStation 5. If you plan to install it in your console, the model with the integrated heatsink is highly recommended to meet Sony's thermal requirements.
Game Mode 2.0 is a software feature accessible via the Western Digital dashboard that uses load prediction to optimize your drive's performance. It helps reduce stutter and improves asset loading speeds by prioritizing gaming data.
Yes, the SN850X is backwards compatible with PCIe Gen3 interfaces. However, you will be limited to the maximum speed of the Gen3 slot, so you will not experience the full 7,300 MB/s read speeds this drive is capable of.
