The primary advantage is accessibility. Once an archive is copied to the console's hard drive (or an external drive), the operating system treats it like any other program folder. You can navigate to the folder via a custom dashboard (like UnleashX or XBMC) and launch the game immediately without swapping discs or mounting virtual drives. This creates a seamless, "digital-only" library that is often faster to access and quieter than running games from a decade-old DVD drive.
