GTA 6 launches on 19 November 2026 and is expected to need around 200GB on PS5. A base PS5 has only about 667GB usable, so a single game fills roughly a third of it. You need at least a 2TB M.2 NVMe PCIe Gen4 expansion SSD with a heatsink (read speed 5,500 MB/s or more). You cannot install GTA 6 on an external USB drive, because PS5 games must run from internal M.2 storage.
Why GTA 6 needs a bigger PS5 SSD
A base PS5 ships with 825GB, of which about 667GB is usable after the system software. A roughly 200GB game like GTA 6, plus day-one patches and the rest of your library, leaves very little room. The PS5 Pro ships with 2TB, which helps, but big modern titles still add up fast.
The fix is an internal M.2 expansion SSD. A 2TB drive is the recommended size: it holds GTA 6 with comfortable headroom for other games, and 2TB usually has the lowest price per terabyte. A 4TB drive suits players who keep a large library installed permanently.
What size SSD for GTA 6?
| Use case | Best choice | Why |
|---|---|---|
| GTA 6 only, tight budget | 1TB | Holds GTA 6 plus one or two other games, but fills quickly. The minimum, not the comfortable choice. |
| GTA 6 plus a library (recommended) | 2TB | Room for GTA 6 and a wide rotation; usually the best price per terabyte. |
| Large permanent library | 4TB | Keep GTA 6 and dozens of big games installed without ever deleting. |
Internal SSD or external drive for GTA 6?
Internal M.2 SSD (required to play)
- PS5 games, including GTA 6, run only from internal M.2 storage.
- Must be M.2 NVMe Gen4, 5,500 MB/s or faster, with a heatsink.
- 2TB is the recommended size for GTA 6 plus a library.
External USB drive (storage only)
- Can store PS5 games and play PS4 games, but cannot run GTA 6.
- Useful as an archive: copy games back to internal storage to play.
- Far cheaper per terabyte, but not a substitute for an internal SSD.
Buy before the launch rush
GTA 6 is the biggest console launch of the decade, and the 2026 NAND shortage already keeps SSD prices firm. Demand around 19 November 2026 is likely to tighten stock and pricing on the most popular 2TB drives.
Buying a compatible 2TB Gen4 SSD ahead of launch lets you preload and avoids paying a premium in the rush. The live table below shows the cheapest compatible 2TB and larger drives on Amazon.co.uk right now.

Frequently asked questions
How big is GTA 6 on PS5?
Rockstar has not confirmed the final size, but it is widely expected to be around 200GB on PS5, in line with other modern open-world games plus launch patches. Plan for a large install and future updates.
What SSD do I need for GTA 6 on PS5?
An M.2 NVMe PCIe Gen4 SSD with a heatsink, a read speed of at least 5,500 MB/s, and at least 2TB so the roughly 200GB game and your other titles fit comfortably.
Can I install GTA 6 on an external drive on PS5?
No. PS5 games must run from internal M.2 storage, so GTA 6 has to be installed on the console SSD or an internal expansion SSD. An external USB drive can only store it, not run it.
Is 1TB enough for GTA 6 on PS5?
It is tight. A roughly 200GB game plus updates and a couple of other titles will fill a 1TB drive fast, so 2TB is the recommended size for GTA 6 plus a library.
When does GTA 6 launch?
GTA 6 is scheduled for 19 November 2026 on PS5 and Xbox Series X|S. Buying storage ahead of launch avoids the rush and lets you preload.
Does GTA 6 need a fast SSD on PS5?
It needs a drive that meets the PS5 spec: Gen4, 5,500 MB/s read, with a heatsink. Any compatible PS5 SSD will run GTA 6 properly; beyond the spec, prioritise capacity and price per terabyte.
