I use SCSI devices primarily becaue you can hook up 15 devices into a machine as opposed to 4 with IDE. I think smooth playback is more of an issue of the drives speed and your CPU/BUS speed.
SCSI goes up to 160 B/s for hard drives only right now. I don't think you will come close to that with a CD or DVD drive.
