I have one in my home machine for video stuff, and i have one in a tax office for the files and database stuff, i run 2 80s seagate satas elsewhere, they are very nice and reliable drives...
I have one I use a a storage drive. Very quiet.
I used to run 2 of them in RAID 0, never any problems with them. I sold one when I bought my 36 GIG Raptors..... should have never done that ! The Seagates were much better in my case.
