This debate is silly. Right now I love Seagates. Quiet, reliable, 5-year warranty. That is a good thing. You all need to let this "deathstar" go. I owned 3 IBM Deathstars. Quitest drive and very fast seek. Loved 'em... and then, one by one, all three died. RMA'd 'em and of the three replacement drives two more died. I am still using those 3 drives today (1 IBM, 2 Hitachi) 24/7. It WAS one bad model (75GXP). That model has nothing to do with today's Hitachi drives. I've got friends that hate any one of the major HDD mnfg for one reason or another. The fact is that all HDDs fail. If you don't back-up your data then you are just asking for heartache. Yes, IBM had a bad model line... now let's move on.
Personally, I would recommend Seagate based on my experience with their current drives. I have no experience with Hitachi's latest drives. From what I read they sound like they're very competitive.
