| Console | Usable space (approx.) | Left after GTA 6 |
|---|---|---|
| PS5 (original) | ≈ 667 GB | ≈ 455 GB |
| PS5 Slim | ≈ 848 GB | ≈ 636 GB |
| PS5 Pro | ≈ 1.8 TB | ≈ 1.6 TB |
| Xbox Series X | ≈ 800 GB | ≈ 588 GB |
| Xbox Series S 512 GB | ≈ 364 GB | ≈ 152 GB (tight) |
These are estimates: the system software takes part of the advertised capacity. Only the 512 GB Xbox Series S is really tight: GTA 6 would take more than half of its usable space.
