Know before you buy
Yes, the WD SN850X meets all of Sony's requirements for PS5 storage expansion. Because it includes a pre-installed heatsink, it is ready to be installed directly into the console's M.2 expansion slot.
While the drive works perfectly as a plug-and-play device, installing the WD_BLACK Dashboard is recommended if you are on a PC. It allows you to enable Game Mode 2.0, which optimizes the drive's performance for gaming, and keeps your firmware up to date.
This model features an integrated heatsink, which makes it physically thicker than standard M.2 SSDs. You should verify that your laptop has sufficient clearance in the M.2 bay before purchasing, as it may not fit in ultra-thin notebooks.
The drive is backward compatible with PCIe Gen 3 slots, but you will not achieve the maximum read and write speeds advertised. To get the full 7,300MB/s performance, your motherboard must support the PCIe Gen 4 standard.
The heatsink helps dissipate heat during heavy read and write operations, which prevents the drive from 'thermal throttling.' By keeping the temperature stable, the drive maintains its peak performance speeds during long, intense gaming sessions.
TBW, or Terabytes Written, measures the total amount of data you can write to the drive before it reaches its wear limit. A rating of 1,200 TBW is very high, meaning you can write hundreds of gigabytes of data every single day for years without worrying about the drive wearing out.
