PlayStation 2 Storage Capacity: No Internal Drive, Games Run from Disc

The PlayStation 2 has no internal hard drive or game storage (except the optional Network Adapter + HDD for a handful of titles like Final Fantasy XI). Games run directly from DVD discs:

• Single-Layer DVD-5: 4.7 GB
• Dual-Layer DVD-9: 8.5 GB (used by larger titles like God of War II, MGS3: Subsistence, GTA: San Andreas)

Game size varies by title—early games ~1–2 GB, late-generation epics 4–7 GB. Save data goes to Memory Cards (8 MB), not the console itself. The PS2 Slim (SCPH-70000+) removed the HDD bay entirely.
