Bloomberg explains that this support for additional drives will come with a firmware update that will unlock higher cooling fan speeds in a news report.
The new next-generation games will only run from the console’s internal storage, which makes only 667 GB available for game installs. And if you know about the new generation games, you can notice that 667 GB can get filled up so fast.
According to Bloomberg, we will able to take a plastic cover off and attach a new storage unit after the new firmware upgrade. But Sony did not confirm the release date of this firmware.
Sony said “explorations for allowing players to store (but not play) PS5 games on a USB drive in a future update are underway.” in November 2020.
Yasuhiro Ootori, VP of mechanical design at Sony Interactive Entertainment’s hardware design division said “Various games will be released in the future, and data on the APU’s behavior in each game will be collected. We have a plan to optimise the fan control based on this data.”
