Know before you buy
If your motherboard already includes integrated M.2 heatsinks, you likely do not need the extra hardware. However, if your motherboard lacks cooling for the M.2 slot, the heatsink version is highly recommended to prevent thermal throttling during long gaming sessions.
Yes, the WD_BLACK SN850X meets all Sony requirements for PS5 storage expansion. If you are installing it in a console, we recommend choosing the version with the integrated heatsink to ensure optimal temperature management.
Game Mode 2.0 is a feature within the WD_BLACK Dashboard software that optimizes the drive's performance to reduce load times and improve responsiveness. It is entirely optional, but it is a useful tool if you want to squeeze every bit of performance out of your drive.
Yes, this drive is fully compatible with Microsoft DirectStorage. This technology allows the GPU to load game data directly from the SSD, significantly reducing load times in supported titles.
You can, provided your laptop has an available M.2 2280 slot that supports PCIe Gen 4. Note that the heatsink version is quite tall and may not fit in many thin-and-light laptops, so the non-heatsink version is usually the safer choice for mobile devices.
TBW stands for Terabytes Written and represents the total amount of data you can write to the drive before it reaches its wear limit. For a 2TB drive, 1200 TBW is a robust rating that ensures the drive will last for many years, even with heavy daily gaming and file transfers.
