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
The volume is in the desktop, I guess. This situation may change as time
on but for now SCSI tends to offer better performance.
