Quick answer: For GTA 6 storage, a PS5 needs an internal M.2 SSD to run the game from extra space, while an Xbox Series X|S needs Microsoft’s official Storage Expansion Card or the internal drive. USB external drives can store current-generation games on both consoles but cannot play them. The install is reported at about 210 GB, which is unconfirmed by Rockstar.

PS5 Notes
Sony specifies a PCIe Gen4 M.2 SSD with a heatsink and a minimum recommended read speed of 5,500 MB/s. Check the console’s current compatibility list before buying.
Xbox Notes
Microsoft’s expansion card plugs into the back of the console and runs Series X|S optimized games at internal speed. Cheaper USB drives are only for archiving and for backward-compatible titles.
How Much Space You Need
- GTA 6: about 210 GB (reported).
- Day-one patch: unknown, so budget extra.
- A buffer of 10 to 15 percent keeps the console from slowing down.

Bottom Line
If your console is almost full, clear space first. Only buy hardware if you play many large games, and check compatibility before you do.
