Sorry >SCSI is OK if you do not want to add anything to it. That would be because it was a PC. SCSI isn't plug-n-play but with fully compliant hardware its main problem was the limit of seven devices + host (for basic SCSI). I ran my PowerMac 6100 with a MO drive, CDRW drive, one of those 5.25" cartridge drive thingies, a hard drive or two, a scanner, and briefly an Exabyte drive (Retrospect wouldn't work reliably with it) in various combinations. I had to use 'SCSI probe' (or whatever it was called) quite a bit. I also have an Apollo or two, although not run up for a few years. They were quite happy with a 5.25" tape cartridge, an Exabyte and several disc packs. They just worked, but the Apollo was a much more expensive machine.
