A recent analysis conducted by Digital Foundry suggests that upgrading the PS5’s SSD can hold some noticeable implications for performance. Digital Foundry used a Samsung 980 Pro SSD in its suite of tests, which is obviously enough quite a bit faster than PS5’s internal storage.
The tests reveal little to no impact on loading speeds and frame-rates in PS5 games, but PS4 games running in back-compat mode do benefit from this bump. Games with relatively long loading times such as The Witcher 3 and Fallout 4 do benefit in a noticeable manner, and so do general transfer speeds across the board.
The PS5’s latest beta firmware allows for expanding the storage using the additional M.2 SSD slot. Gigabyte, Seagate, and WD have revealed their PS5-compatible SSDs, which boast speeds around the same 7,000 MB/s mark as the Samsung 980 Pro. We recently compiled a list of the best SSDs to consider for the PS5, which you can check out below.
