There's a link to a review of new ATA/100s on Tom's Hardware I found while on StorageReview.com that are quieter and faster than the venerable Deskstar 75GXP that has led the pack. The new IBM drive wasn't available for testing. Fujitsui offers 500Mbps and has fluid bearings, also lower temp than any of the others. 20GB starts at $109 at Computers4Sure.com
