However, in reality, your typical user will be more than happy with most fast IDE devices available. I've used Buddha in the A2000 and A3000, Power Flyer Gold in the A1200 and the FastATA4000 in the A4000 and even though I also have SCSI in the A1200, A2000 and A3000 the IDE options are better for me because I have plenty of cheap, large and fast IDE devices littering my office without having to scavenge some dusty 4x SCSI CD ROM drive off eBay.
I think the user can live with a little extra load on the CPU for the time it takes to load a 256KB file or load Deluxe Paint.
