New PlayStation 5 system software rolling out in beta today finally unlocks the long-promised ability to expand the system’s 667GB of usable internal storage, using M.2 SSDs that fit certain technical and physical requirements.
As listed on a new PlayStation support page, the new system software supports 22 mm-wide M.2 drives using the PCIe Gen 4 standard. Single- or double-sided drives with storage sizes ranging from 250GB to 4TB should work with the console.
Sony recommends that any PS5 expansion drive have a sequential read speed of at least 5500MB/s but warns that even then, “not all games are necessarily playable with the exact same performance provided by the PS5 console’s internal Ultra-High Speed SSD.” The company also recommends a heatsink (either built in or attached by the user) to aid with heat dissipation but warns that the heatsink should only rise 8 mm “above the board” to help ensure the entire housing can fit in the PS5’s 11.25 mm-high compartment.
