Did that w/ both of my systems a year back. Got promise ATA133 and ATA100 on the systems, 2 HDs, CDRW and DVD each, running as Master on its own channel. Worked well, but the cables are killing me, and controller card check slows down bootup time. Switched back to configuration I mentioned and took out the controllers, and I'm getting the same speed. Again, unless you're running an ancient system w/ ATA33 or 66, putting optical drives on the same channel will not be a problem. But like RDG said, try out different configurations and do benchmarks w/ Sandra.
