Best SSD & storage for GTA 6

GTA 6 is expected to be large, so free, fast storage is one of the highest-value GTA 6 upgrades. Current-gen games must run from the console SSD (PS5 internal slot) or a certified card (Xbox), so the type of drive you buy depends on your console.

Rockstar has not published a final install size, so treat capacity advice as headroom planning. A 2TB drive is the comfortable sweet spot for 2026. Confirm the current retailer terms and exact model before buying.

What to check before you buy GTA 6 storage

PS5 needs a PCIe 4.0 x4 M.2 2280 NVMe SSD rated ~5,500 MB/s or faster, with a heatsink.
PS5 size limit: the drive plus heatsink must fit within 110 x 25 x 11.25 mm.
Xbox Series X|S uses certified Storage Expansion Cards (Seagate or WD_Black C50) — standard SSDs do not work for current-gen games.
2TB is the sweet spot; 1TB is the practical minimum for a big game plus your library.
An external USB SSD is only for storing/archiving current-gen games, not running them.

FAQs

How much storage do I need for GTA 6?

Rockstar has not confirmed the install size, so plan for headroom. A 2TB drive comfortably fits a large game plus the rest of your library; 1TB is the practical minimum. We will update this once an official install size is published.

Can I use any NVMe SSD in a PS5?

No. The PS5 needs a PCIe 4.0 x4 M.2 2280 NVMe drive rated around 5,500 MB/s or faster, with a heatsink, fitting within 110 x 25 x 11.25 mm. The drives above meet these requirements.

Can I install GTA 6 on an external USB drive?

Current-gen games must run from the console SSD (PS5) or a certified expansion card (Xbox). An external USB SSD can store or archive current-gen games to free up space, but you move them back to fast storage to play.
