Plan on freeing up or adding storage before GTA VI.The download size isn’t confirmed, but credible estimates land around 150–200 GB — and a PS5 only gives you about 667 GB usable out of the box. For PS5, the fix is a Gen4 M.2 NVMe SSD with a heatsink(1–2 TB); for Xbox Series X|S, it’s the official Storage Expansion Card.
Unconfirmed
Rockstar has not confirmed the GTA VI download size. The ~150–200 GB figure is a community estimate. Treat it as a planning number, not a fact — we’ll update this the moment an official size is announced.
Do you actually need more storage?
Check your free space first. If you keep a few big games installed (each modern AAA title can run 100 GB+), a GTA VI install in the 150–200 GB range may not fit on the ~667 GB a PS5 gives you. You have two options: delete games you can reinstall later, or add a drive so you never have to choose. If you preload — which opens November 12 — the space needs to be free by then.
Best SSD for PS5
The PS5’s expansion slot needs a Gen4 M.2 NVMe SSD rated at 5,500 MB/s or faster, fitted with a heatsink (many drives include one). A 2 TB drive gives you comfortable room for GTA VI and the rest of your library; 1 TB is a cheaper option if space is tight. Gen4 NVMe drives commonly run in the ~$100 (1 TB) to ~$130–180 (2 TB) range.

Confirmed
Both the WD_BLACK SN850X and Samsung 990 Pro are Gen4 NVMe drives that exceed the PS5’s 5,500 MB/s requirement and come in heatsink versions. We recommend on specs and fit — never on what pays us.
How to install a PS5 SSD
The PS5 has an officialM.2 slot under the side panel — using it keeps your warranty intact. Power down fully, remove the panel and the slot’s screw cover, seat the drive, replace the cover, and the console will prompt you to format it. Follow Sony’s official walkthrough (linked in Sources) rather than a random video.
Xbox Series X|S
Xbox keeps it simple: expandable storage uses the official Storage Expansion Card that plugs into the back of the console — no installation, full next-gen performance. It comes in 512 GB, 1 TB, and 2 TB sizes.

What to avoid
Don’t buy a slow or heatsink-less drive to save a few dollars — the PS5 will reject drives that don’t meet the speed spec, and a missing heatsink risks throttling. Skip no-name “PS5 compatible” listings without clear Gen4/NVMe/heatsink details, and ignore anyone selling GTA VI keys or “early downloads” — those are scams. Buy storage from reputable retailers only.
Possibly. GTA VI's download size isn't confirmed, but estimates of ~150–200 GB against a PS5's ~667 GB usable mean many players will want to free up space or add a drive — especially if you keep other large games installed.
How much storage does GTA 6 need?
