There are already SATA optical drives available however they are few and far between because the interface provides no benefits to the devices.
A 52x drive can't even saturate a ATA33 channel let alone a ATA66/ATA100/ATA133/SATA150 channel.
52 x 150KB/sec = 7.8MB/sec
72 x 150KB/Sec = 10.8MB/Sec
You'd need a 220x CDROM drive to saturate a ATA33 channel
Even a 16x DVDROM doesn't do it 16 x ~1.3MB/Sec = ~21.
You'd need a 25x DVDROM drive to saturate a ATA33 channel
