I'm thinking of buying an external drive from OtherWorldComputing. I'm looking at the 250GB Mercury Elite Pro 7200RPM FireWire 800+USB 2.0/1.1 that uses a Hitachi DeskStar 7K250 drive in it. Does anyone have any experience with these drives - how loud are they? I'm looking for a 250 GB (or more) HD but want it to be cool (temp-wise) and quiet. Any suggestions would be most appreciated.
