Well, received my Seagate 5400.2 rpm 100GB from Newegg yesterday (Thursday) after ordering it on Monday.
So I have only been using it for 24 hours but the first thing I noticed was how flippin' quiet it is. Even quieter than the 4200 rpm Fujitsu it replaced. I read that the Seagate drive was near silent but you always take statements like that with a grain of salt. Well it's 100% true...it's amazingly, incredibly silent! Speed is pretty noticable, of course, over the Fujitsu. While most offer a 3 year warranty Seagate backs theirs with a 5 year warranty. Now do I think I'll be using this drive in 4 or 5 years? Most likely not, unless for an external back up, but it's still nice to know that you have that incredible warranty...I guess.
Great drive, quick & super quiet. Highly recommended.
