Oh boy. The new generation of consoles are getting blazing-fast SSD storage, but the cost is that it’s going to be expensive to have enough storage for these games.
For the PS5, it has been confirmed in an FAQ post that PS5 games won’t be able to be stored on an external USB drive. This is what’s written on the post:
Can I store or play PS5 games from a USB drive?
No, players cannot transfer PS5 games to a USB drive. PS5 games must be stored on the console’s internal ultra-high speed SSD for gameplay. Explorations for allowing players to store (but not play) PS5 games on a USB drive in a future update are underway.
You can, however, store and play PS4 games from a compatible USB drive connected to PS5.
Sony also confirms that the internal SSD slot is currently disabled, and recommends not to buy any SSD with the intention to use it on the PS5 at the moment.
The PS5 has a built-in 850GB storage- only 667GB of it is usable for game installs. And as revealed here, there’s no way to put more PS5 games in storage at the moment.
However, Sony will be sharing more details on what SSD is compatible for the PS5 internal slot in the future. And a future update will enable the use of the SSD slot, plus allowing PS5 games to at least be stored on external storage.
The PS5 won’t run games on an external USB drive, even if it is an SSD. However, you can still store and play PS4 games on PS5 from an external drive.
The PS5 launch begins on November 12, and then November 19 for most of the world. Though no details about its launch in Southeast Asia aside from Singapore has been revealed- so it’s safe to assume it will probably be arriving here next year.
