And of course more and more servers based around the blade design are begining to use laptop drives as well. The admins in this sector would rather pay more to avoid dead drive issues.

People keep saying desktop IDE could replace SCSI. SCSI still has a speed advantage, and is also more reliable. Sure it may be the same drive platters and heads in certain units, but that board full of electronics on the bottom of SCSI drives is doing something... And I have found that laptop drives usually fall between SCSI and desktop IDE for reliability.
