Sony has provided an overview of its first major update for the PlayStation 5, which will begin rolling out globally tomorrow. The new update’s biggest feature relates to expansion and management; users can now transfer their PS5 games to USB extended storage from their console’s internal storage (previously, only PS4 games could be stored on external HDD/SSDs). The new update also adds various social features for both PS4 and PS5 consoles (e.g., cross-generation Share Play), enhanced control and personalization options for PS5 consoles, and new features for the PlayStation App. Unfortunately, Sony is still working on enabling the PS5’s M.2 slot for owners who’d like to expand their system’s relatively limited internal storage.
Because PS5 games are designed to take advantage of the console’s ultra high-speed SSD, PS5 titles can’t be played from USB extended storage. PS5 titles also cannot be directly downloaded to USB extended storage. However, games that you transfer or copy back to internal storage will automatically update when applicable. In addition, you can select which game modes you want to install (such as campaign or multiplayer) for select titles that support the option.
