It all happens to be the luck of the draw....
In my personal uses, I've used maxtor, seagate, western digital, and IBM..
Half my western digital and IBM drives have died, all my maxtor drives have died, none of my seagates have died. Seagates also have the longest warranty, 5 years on pretty much all their drives. I've had two of them in a raid 0 for around 6 years, 1 stand alone for about 3 years, and 2 newly purchased ones that are about 8 months old. all going strong.
