I want to know the difference between Sony PS3 12GB & 500GB. Is both HDD used for saving games or used for saving movie songs & pics?
12gb does not have hard drive and hard drive caddy. it just has 12gb onboard storage (~9gb available for use). can be upgraded with compatible hard drive (2.5", sata, 9,5mm) and caddy. you can use onboard 12gb storage OR hard drive (not both). 500gb does not have that onboard storage.
storage space is used for the same things (savegames, game data, pics, videos...)
