No, you cannot play GTA 6 from a USB or external hard drive. GTA 6 is a PS5 and Xbox Series X|S game, and those must run from the internal SSD, a PS5 M.2 SSD, or an Xbox Storage Expansion Card. Official
An external drive can store GTA 6 while you play something else, and it is great for moving other games out of the way.
USB and external hard drives can store GTA 6 but not run it.
Current-generation games depend on very fast storage to stream their worlds, so Sony and Microsoft only allow them to run from fast internal or approved storage. That rule is set by the consoles, not by Rockstar, and it covers GTA 6.
Where GTA 6 can run
| Storage | PS5 | Xbox Series X|S |
|---|---|---|
| Internal SSD | Runs | Runs |
| PS5 M.2 SSD (expansion slot) | Runs | Not applicable |
| Xbox Storage Expansion Card | Not applicable | Runs |
| USB external SSD or hard drive | Store only | Store only |
How an external drive still helps
- Move other games off the internal drive to make room for GTA 6. On PS5, PS4 games can even be played straight from USB.
- Park GTA 6 on USB if you take a break from it, then copy it back. Copying is much faster than downloading about 200 GB again.
Steps are in how to free up space for GTA 6.
Why consoles block external drives for new games
The PS5 and Xbox Series X|S SSDs read data several times faster than a typical USB drive and many times faster than an external hard drive. Modern games stream textures, buildings and traffic from storage as you move, instead of hiding it behind loading screens. GTA 6's world is built around that speed, so running it from a slow drive would cause pop-in and stalls. Sony and Microsoft avoid that by only allowing current-generation games on storage that meets their speed rules.
Picking a USB drive for storing games
For storing games you are not playing, any USB 3 external drive of 1 TB or 2 TB works. A portable SSD copies games back faster than a hard drive, but a hard drive is cheaper per terabyte and fine for parking games. Format it on the console when prompted. The storage calculator shows how much space you need to clear first.
If you need more space to run GTA 6
On PS5, add an M.2 SSD: see the best SSD for GTA 6 on PS5. On Xbox, add a Storage Expansion Card: see Xbox expansion cards for GTA 6.
