I've been using Seagate Barracudas since they came out with no failures personally. I've installed hundreds of others into customers' comps. Only one failure, after five years of 24/7 (it was backed up).
They have 5 year guarantees and are a good blend of reliability, performance, & price.
I had previously narrowed down my choices to the new Samsungs and Western Digital, thinking that Seagate was more speed and performance oriented, toward gamers etc., so your suggestion sheds new light on the equation, thanks pscowboy
