I like Maxtor; Their RMA policy doesn't suck (they will ship you a drive if you provide a credit card number they can "hold" against, then you ship the old one back). I did get one bum drive from them, a 60gb when those were new. They fixed it right off.

The 40gb that went bad was after several years in an always-on but low traffic fileserver. it was in my wife's PC having just been "retired" from fileservice when it failed.
