I keep getting messages informing me that I'm running out of space on my PS3s HDD, mostly due to the amount of space the GT5 game data is taking up. If I remove the game data and run it purely from the disk, how much slower are loading times?
If I had to guess, probably somewhere between 50-100% longer. You might consider buying a cheap flash drive and start offing data you don't need if you need HDD space. Move old save files onto your PC and delete Game Data for games you don't play anymore.
