I've run the gauntlet of all brands, hand me down drives, purchased my own, fixed immediate family member's computers. Since 1996, I've had 5 hard drives fail on me. 3 WD's, 1 Deathstar, 1 Samsung. The brands that I've never had fail on me were Maxtor and Seagate. I even have a Maxtor circa 1997 that is fully functional, and its been abused.
And I've run into this thread across many forums and everyone claims are different. I find it very similar to cars (Chevy, Ford, Honda, Toyota etc).
Not every model is the same across a brand. Not every brand produces perfect drives.
