I can't wait to get my hands on a few of these drives. I never had an IBM drive I couldn't return. IBM are always the top performers and ususally fall to second best only when a new generation of drive comes out from another company.
IBM are performance hard drives IMO, if you want a hard drive that has been tweaked "down" or "safe", you have plenty to choose from. IBM are the same as we enthusiats are. We tweak our boxes for optimum performance, we run hard, and run them hot. You don't see a stock automobile blow a gasket when that light turns green, but your sleeper that you just finished tuning and tweaking just may, but if it doesn't you get a great rush of speed.
I take precautions with hard drives just like I do with processors, vid cards, or memory. I make sure my hard drives are throughly cooled.
So what's my point?? If you are going to have a hard drive go bad, it might as well be the top performer.
