A PS3 uses a user-replaceable 2.5-inch SATA drive. A conventional HDD is inexpensive; a SATA SSD is quieter and can improve menus and some loading times, although the console limits peak speed.
Back up first, fit the new drive in the original caddy, then place PS3UPDAT.PUP in PS3/UPDATE on a FAT32 USB drive. A blank drive normally requires the full reinstall flow.
Which hard drive or SSD fits a PS3?
Use a 2.5-inch SATA drive, 9.5 mm or thinner. A 7 mm SSD also fits when secured in the caddy.
| Requirement | Recommended choice | Why it matters |
|---|---|---|
| Form factor | 2.5-inch SATA | Desktop 3.5-inch drives do not fit. |
| Thickness | 9.5 mm or thinner | A 7 mm SSD fits when mounted correctly. |
| Capacity | 500 GB to 1 TB | This is the low-risk practical range. |

Back up saves and prepare tools
Synchronize trophies where possible, verify important saves, and keep the old drive until restoration succeeds.
- Use Settings > System Settings > Backup Utility for a broad local backup.
- Copy important saves separately when the game permits it.
- Prepare a Phillips screwdriver, FAT32 USB drive, replacement drive, and controller cable.
Remove the old drive and transfer the caddy
Original, Slim, and Super Slim systems use different covers and tray directions. Never force the caddy.
