I've worked in the IT field for 14 years now and have seen failures of pretty much every brand of hard drive. Maxtor, connor, seagate, western digital, toshiba, hitachi, ibm, samsung, etc.
Generally speaking, my worst experiences have been with Maxtor and my best experiences have been with WD and Seagate. Between WD and Seagate, I tend to prefer WD these days as they haven't have the cataclymic failures with certain firmware versions such as the infamous Seagate 7200.11.
Well our oldest son went MAC on us, pretty damn smart of him I think!
No more late night upgrades, blue screens and etc!
Also had handfuls of MAC's over the years in my work environments, and they too fail I'm afraid.
Motherboards give out, drive controllers die, monitors give out. If you are under the impression that they never die, just sit outside an Apple store at the mall for an hour or so and see how many people lug in an imac, macbook, etc for repairs. It's not all sunshine and rainbows.
