i've had the 500gb 7200.11 hard drive for over 3 months now with zero complains. it's really quiete compared to my old 160gb seagate. i haven't run any benchmarks but i;ve experienced no problems. it stays really quiet. i can only hear it when windows starts up and all my programs are loading. i gues i need to defrag it. i dont own any samsung hard drives so i can't compare.
