hello! I was wondering if there is any software tools around that can tell if a hard drive is spinning at 7200rpm? or way to test for performance? the reason i'm asking, given the price of new hard drives now a days, I am looking to upgrade my gaming system and would like to hold off buying a new hard drive. mine is a SATA Seagate 500gig and is working great but it's about 5 years old. the age kinda worries me but it still works great, did you think I should delay getting a new one for a while?
