The Sony PlayStation 3 is a next-generation video game home console. Since its 2006 debut, Sony has released numerous versions of the console, many of which vary in available hard-drive sizes. As of May 2011, the different hard drive sizes available in PS3 consoles include 20 GB, 40 GB, 60 GB, 80 GB, 160 GB, 250 GB and 320 GB. You can check and see how large your PS3's hard drive is within the settings menu.
Turn on the PlayStation 3. Log in to your account.
Navigate left until you reach "settings."
Press X to open the system settings.
Locate the heading "system info" within the menus. The hard drive space will be listed in an X/Y format, where X is the amount of free hard drive space you have and Y is the total amount you have on your system.
The total amount of hard drive space will always be a little bit less than the packaging states. For example, new 60 GB PS3s will generally have 55 GB of total space.
