Not as far as I know. Using a SATA DVD/RW is just becasue you have migrated
to MOB to a new one with SATA. I depend more in the model of DVD that you
are using, than the interface.
SATA was designed to supercede ATA (or sometimes referred to as Parallel
ATA) .. has some really fast bus speeds, enhanced raid capability and
platter command queuing....
