How much storage does PS5 actually have?
The PS5 comes with 825GB. After the system software, you have ~667GB usable. • 1-2 AAA games fill this completely • Call of Duty: Modern Warfare III = 130GB • Final Fantasy XVI = 150GB • EA Sports FC 25 = 45GB • Elden Ring = 60GB You'll run out within weeks if you play multiple games. External storage is essential.
External SSD vs Internal M.2 — which should you buy?
PS5 allows two storage solutions: **External USB SSD (via USB 3.1)** • Stores PS4 games only (not PS5 native games) • Cheaper: $100–$150 for 2TB • No installation required — just plug in • Can unplug and use on PC/Mac • Speed doesn't matter (USB 3.1 is the bottleneck) • Best for: Playing lots of PS4 games **Internal M.2 NVMe (via expansion slot)** • Stores PS5 native games only • More expensive: $200–$300 for 2TB • Requires installation (takes 20 minutes) • Dramatically faster load times • Dedicated to PS5 (can't remove easily) • Must meet Sony's strict 5,500 MB/s requirement • Best for: PS5 game library **The verdict**: If you play both PS5 and PS4 games, get both (2TB external + 1TB internal). If PS5 only, get internal M.2. If PS4 only, external USB is all you need.
Sony's M.2 requirements — what actually works?
Sony is picky about M.2 drives. The drive must be: ✅ NVMe M.2 2280 form factor ✅ PCIe 4.0 (not 3.0) ✅ 5,500 MB/s minimum sequential read speed ✅ Less than 110GB capacity (cooling) ✅ 7mm or less in height (heatsink) Drives that work in 2026: • Samsung 990 Pro (7,450 MB/s) ✅ Best overall • WD Black SN850X (7,100 MB/s) ✅ Best value • SK hynix Platinum P41 (7,000 MB/s) ✅ Budget option • Crucial T700 (5,000 MB/s) ❌ Below 5,500MB/s — may cause errors Drives Sony officially tested: Samsung 990 Pro, WD Black SN850X, Seagate FireCuda 530. Other drives above 5,500 MB/s usually work but aren't guaranteed.
PS5 storage setup guide (step-by-step)
**Adding External SSD (PS4 games)** 1. Buy USB 3.1 portable SSD (Samsung T7, SanDisk Extreme) 2. Plug into PS5's back USB port 3. PS5 prompts to format — confirm 4. Select which PS4 games to move (Settings → Storage → Transfer Games) 5. Games move automatically (takes 5–10 minutes for 100GB) **Adding Internal M.2 (PS5 games)** 1. Buy qualified NVMe SSD (Samsung 990 Pro, WD Black SN850X) 2. Power off PS5 completely 3. Remove side panel (unclip, don't unscrew) 4. Open M.2 expansion slot cover 5. Insert drive at 30° angle, push down, screw in 6. Replace cover and side panel 7. Power on — PS5 auto-detects and formats 8. Install PS5 games to the expansion slot (Settings → Storage) Total time: 20 minutes. No technical skill needed — any adult can do it.
Price and value in 2026
**Best external SSD for PS4 games:** Samsung T7 (2TB) — $300, 1,050 MB/s, highly reliable. Overkill for PS5 USB port (only 400 MB/s usable) but works perfectly for PS4. **Best value internal M.2 for PS5:** WD Black SN850X (2TB) — $240–$280, 7,100 MB/s, excellent thermals, 5-year warranty. Best cost-per-TB and reliability. **Best overall internal M.2:** Samsung 990 Pro (2TB) — $280–$320, 7,450 MB/s, proven with PS5, excellent customer support. **Budget option:** SK hynix Platinum P41 (2TB) — $200–$240, 7,000 MB/s, reliable, underrated. Slightly slower than 990 Pro but still excellent. **Total cost for full PS5 setup:** 2TB external (PS4 games) + 1TB internal (PS5 games) = $350–$450. Expands your PS5 from 667GB to 2.6TB usable — enough for 20+ AAA games.
