PS5 has an internal storage expansion, but Sony has confirmed the functionality won’t be supported at launch.
Sony detailed that the external SSD expansion support will be “reserved for a future update”, meaning players will need to rely on the PS5’s reported 667GB SSD and USB 3.0-powered external hard drives for storage. PS5 games cannot be played from USB 3.0-powered drives.
Sony also detailed that the M.2 SSDs will have to exceed transfer speeds of 5.5GB/second over a PCI Gen4 bandwidth connection. A list of supported drives has not been issued by Sony yet, with tech lead Mark Cerny advising customers to hold off on buying a drive just in case it’s not compliant.
PS5 heads to retail stores on 12 November.
