Yes, the Black SN7100 powered by SANDISK works with the PS5, as long as you mount it with a suitable, low-profile heatsink. The SSD fulfils all the technical requirements of the PS5: It is an M.2 2280 with PCIe 4.0 ×4 interface and, with a read rate of 7250 MB/s, offers significantly more than the minimum 5500 MB/s required by Sony. The heatsink together with the SSD must not exceed a maximum total thickness of 11.25 mm. After the physical installation, you can format the SSD via the PS5 settings and then play PS5 and PS4 games directly from the hard drive.
