Designed for PlayStation 5 consoles

The WD_BLACK SN850P is an officially licensed internal SSD built specifically for PS5 consoles. It uses the M.2 2280 form factor and connects through a PCI-Express 4.0 x4 interface. A pre-installed heatsink carries the PlayStation logo and is shaped to fit the console’s expansion slot without modification. The package includes a 14-day trial of PlayStation Plus Premium | Deluxe.

Suits PS5 owners who want plug-and-play expansion

This drive is intended for players who need more space for their game library and prefer a drive validated by Sony. It is not aimed at desktop PC builders who might want a drive without the console-specific heatsink or firmware tuning. Buyers without a PS5 console should look at other WD_BLACK models.

4TB capacity with high endurance

The 4TB model can hold roughly 100 games, leaving ample headroom for large modern titles and downloadable content. Sequential reads reach up to 7300 MBps and writes up to 6600 MBps, while random performance hits 1,200,000 read IOPS and 1,100,000 write IOPS. The drive is rated for 2400 TBW and 1.75M hours MTTF, so heavy daily writes are well within its lifespan.
