If you stay with the top 2 companies, western digital and seagate, you should be fine. However, I would agree that right now ive had more seagate drives go bad then western digital. What particular series of drive have you been getting and where did you get them?
Since 2001, I've only had one hard drive quit on me, a Seagate, six months after the five year warranty ended.
I have used WD Protégés and Blues since 2004 and they just won't die; my PC runs 24/7.
