Like I said gaming is what matters to me, nothing else. HDD benchmarks are what 3D Mark scores are for CPUs and GFXs, E-penes.
I take it you don't game, or at least play BF2 or else you would know that being on the map first equals "POWN YOU"
Being first on the map means nothing... while the map loads i do other stuff, so it takes longer to load... and then who is there too shoot when your first?
And some map's have time limits up too 60sec so everyone can load at the same time.
Like I said, it depends much more on the rest of your system then HDD RPM.
