>From what I've been told (by one of the Linux SCSI developers) one
generally gets
better performance from SCSI than from IDE or SATA. This is because SCSI
tends to
use fewer interrupts per I/O and that SATA vendors have not implemented
all the
features of SATA that would make the disks suitable for server class
machines. 
The volume is in the desktop, I guess. This situation may change as time
goes 
on but for now SCSI tends to offer better performance.
