Personally, I have several machines with various hard drives. I had bought a Quantum that I had RMAed 4 or 5 times before I got one that worked. Even so, it ran slow as a slug. That one is still running after 4 years. I have had another Quantum crap of out on me, and 3 Western Digital Caviars crap out, but these crapped out long after the warranty expired so I guess they are pretty reliable. I have a pretty reliable Seagate hdd in another one of my comps, and it is running fine after 3 years. I had a Deskstar 60GXP that crapped out after 8 months, and I don't dare touching another IBM hdd. I also have a Travelstar in my lappy, and all I can say is that it is loud and slow... Right now, I'm using a WD800JB to replace my failed Deskstar, and it seems fine, but I have only been using if for couple of weeks. I had a friend though who had a WD800JB raided that blew up and then the master boot record failed though... And my vote goes to WD for being reliable over the years and very fast.
