The Western Digital Black SN850 NVMe SSD with heatsink meets Sony’s PS5 storage expansion requirements and the drive is currently being tested.

Yesterday, manufacturer Seagate confirmed that its upcoming FireCuda 530 PCIe Gen4 NVMe SSD is among the first drive to be compatible with Sony’s next-gen console. Alongside this exciting announcement, Sony released the first PS5 system beta update with support for M.2 storage expansion drives. Unfortunately, only those in the beta program in select countries will be able to try out the long-awaited storage expansion option before it becomes available to all PS5 owners.
