I've read something similar indeed.
Aswell as most IDE disks really do have less quality components. Scsi
disks have also smaller, thicker platters to enable them to run more
stable and on higher speeds, larger magnets etc etc.

http://www.tweakers.net/reviews/362/3 In the second-last paragraph is a
summary of Maxtor's view on the differences between ATA and SCSI.
