I know I went with SCSI, originally, because I had actually purchased two drives -- the huge one, and another one that was a bit faster but smaller and something had led me to believe that SCSI lent itself better to that configuration. I can't remember, specifically, what though.
I recall with CD-ROM drives -- earlier ones -- it was similar. Actually, in a few ways it was worse because the earliest CD-ROM drives came as SCSI or "Parallel Port to SCSI" which I'm not sure anyone ever got to work completely right.
But ... and I could just Google it but I'm being lazy ... I recall it had something to do with Bus Disconnection and Native Command Queuing in SCSI that allowed the CD-ROM drive and the HDD to operate without waiting on one another (as much?).
I know SCSI drives basically disappeared once IDE drives became common. You didn't see SCSI controllers often outside of servers, ever, in the PC world except for a brief period when that was the most common CD-ROM drive.
