Uncompressed PlayStation 2 games occupy a massive amount of digital real estate. A single-layer PS2 disc holds up to 4.7 GB of data, while dual-layer titles like God of War II swell past 8 GB. Storing a comprehensive library using traditional formats rapidly exhausts the storage capacity of hard drives, solid-state drives, and handheld devices.
