Serial ATA CD-Rom Drives?

OutRigged asks: "With Serial ATA hard drives starting to go mainstream, and being almost equal in price to their parallel equivalents, one would think we'd have Serial ATA CD-ROM drives by now. Yet wherever I look, all I see are PATA based CD-ROM drives. It's obvious that an optical drive will benefit little, if at all from using SATA, but why not switch for the sake of the cable size? CD-ROM drives are usually at the top of the case, and with the 1m limit in length, along with the small size of the cables, I see no reason not to use a Serial ATA interface in a CD-ROM drive."
