In order of preference:
- SCSI controller on your accelerator card.
- Zorro III DMA SCSI controller (A4091 or FastLane Z3)
- Zorro II DMA SCSI controller with some Z2 FastRAM (GVP HC+8/Oktagon 2008 etc)
- On-board IDE.
- Zorro II polled IO SCSI controller.
If you have a sufficiently awesome CPU card, you might prefer the on-board IDE to the Z2 DMA solution, but then again, any CPU card that's good enough probably has a SCSI option anyway.
