The Pioneer DVD-116 is ATA/66. (DMA Mode 4). But if you are going to mix-n-match devices that are different speeds ... do it on the secondary channel ... not the primary. Keep your ATA/100 devices on the primary, and everything else on the secondary.
The DVD-ROM should be the Secondary Master. You'll find this recommendation on the Pioneer site. Otherwise, you might have problems when doing firmware upgrades.
If you put the DVD on the primary channel with the hard drive ... it <i>will</i> limit the bandwidth of the drive. Not a great deal, but some. No device on an IDE cable can run faster than the slowest device ... <i>and that's a fact.</i> Considering that the hard drive is still the biggest performance bottleneck in a modern system, why slow it down?
I agree with Blessedman ... an ATA/100 card might be a good investment, especially since almost all IDE CD-RW's are ATA/33. I woudn't put an older burner on the same cable with the DVD unless it supports Burn-proof, or you'll have problems copying CD-to-CD. Coasters ... good for coffee cups; bad for data.
And, of course ... RAID 0+1 is not only fast, but an excellent upgrade path. Think of what you could do with four matching hard drives, striped and mirrored!
