As i think, the problem in FPS is not because of bad HDD. Imo if you get maximum of 60fps in game, like me... When recording for example at 30fps with fraps, you can see that 30fps of theese full 60 will stay in game, other 30 go to fraps. So 30=30, if the fps is less than 25 somewhere, there are already little lags
