Quick answer: Xbox Series X|S-optimized games generally cannot be played directly from ordinary external USB drives. They can be stored there, then moved back to the Xbox internal SSD or an approved Series X|S storage expansion card to run. GTA VI is announced as a native Series X|S game.
Compare your three options
| Storage option | Stores Series X|S games? | Runs optimized Series X|S games? |
|---|---|---|
| Xbox internal SSD | Yes | Yes |
| Compatible Series X|S expansion card | Yes | Yes |
| External USB HDD/SSD | Yes, when supported | Generally no; move the game back first |
Why a fast USB SSD is not the same as an expansion card
Even a high-speed USB SSD does not automatically meet the Xbox Velocity Architecture requirements for directly running Series X|S-optimized games. Seagate, a licensed storage supplier, specifically distinguishes standard USB drives from expansion cards that can run optimized titles.
What to do if GTA VI is saved on USB
- Connect the USB drive correctly and confirm Xbox detects it.
- Open My games & apps → Manage → Storage devices.
- Choose the installed GTA VI content and select the console’s Move or copy action when available.
- Move the supported game installation to internal storage or a compatible expansion card before attempting to run the native version.
Which USB drives can store your existing games?
Seagate specifies at least 128 GB capacity and USB 3.0 or later for Xbox game storage. Xbox One games and some backward-compatible titles can often run from USB, but GTA VI’s native Series X|S edition is not such a game.
Avoid losing data during transfers
Follow your console’s exact prompts, check the target storage capacity, and avoid choosing any save-data deletion option unless you fully understand the consequences. A game-data transfer is not the same as migrating Xbox saves to PlayStation or vice versa.
