I used to always say go maxtor till my 2 Max 10 200gb drives failed within 2 weeks of each other, when I bought them from newegg it stated 3 year warranty. The drives however showed up as not being under warranty at maxtors website. Maxtor refused to honor it so I went Seagate, I really like them and their 5 year warranty makes me really happy. Their performance is great and the new 7200.10's run quiet and pretty cool. I would recommend the Barracuda ES line, they are like 5% higher in price but they are supposedly business optimized for increased reliability, lifespan and RAID performance. I hear good things about the Western Digital RE line which is their answer to the Barracuda ES and also has a 5 year warranty. Ohh and last thing, HDDs are so cheap these days you might want to at a minimum buy 2 of them and have one mirror the other in a RAID 1 config that way you dont lose your important 100's of gigs of data.
