Okay basically a question of curiosity here. I've got my beautiful little gaming pc with a 2TB caviar black 7200rpm hdd which currently has the os and all data and games installed on it. I've recently came into possession of a 320GB 5400rpm hdd which I know isn't great but I figured I may as well use it. Any ideas if there would be a performance increase or decrease from installing games on this drive or simply using it for my os? I realise if being used to boot my boot time would be slower, but would my games see any performance increase?
