Hi Guys
From experience we get PS3 320gig consoles in that are more than 3 years old and they haven't even used up half the space on their PS3 as yet. I have a 320gig drive in my Xbox since 2012 and still haven't even used 100gig yet with 3 profiles and games like GTA, Farcry and other games that load to the hard drive.
As Keepa34 says 320 is more than enough space.
