It’s a great way to extend the storage capabilities of your PS5 console, and you can seamlessly copy your PS5 games back to the console’s internal storage when you’re ready to play. It is faster to reinstall PS5 games from USB extended storage than to re-download or copy them from a disc.
> 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. > New Trophy Settings and Stats Screen. The level of trophies that results in automatic capture of a screenshot or video clip can now be customized — so you can now choose to only capture and save images/videos of moments when you earn higher-grade trophies, like Gold or Platinum. We’re also introducing a new player Trophy Stats screen, where you can check out the summary of your trophy level and status at a glance.
