When it comes to hard drive installs on the PS3, this can often cause an issue for gamers, as freeing up valuable storage space can become a pain. The reason why I decided to mention this issue again is because Gran Turismo 5 offers an optional hard drive install.
Just Push Start reports that Kazunori Yamauchi, announced that the PlayStation 3 racing sim will require 10GB of free storage for install or 256MB to just run the game — although there is a downside to that.
For those who are unable to fully install Gran Turismo 5 to the hard drive will not get the full benefit from the game, as performance and overall smoothness will be compromised. My advice it to have a look around and start deleting anything that is not longer needed.
