Since I started with GT5 the only (big) flaw for me were the loading times of basically everything in the game. Also the game used lots of Gb from my smaller harddrive. I have the second generation 40Gb PS3. Yesterday I replaced this 5400rpm HD for a 7200rpm 500Gb harddrive. I can inform you it will give you seconds of waiting time back So far pleased with it. Those drives only cost about 50-60 euro at the moment. Replacing is 5 mins, backup and restore is about 45 mins each.
