Hope to have a Promise controller driver running soon, and that will allow a total of 8 of the little IDE jellybeans (some people have other names for them, but those names aren't very polite) in my machine. :-). Don't get me wrong, I want a few Cheetah drives in my collection also, but for price/performance in a workstation (not server) environment, the IDEs are not that bad. The biggest complaint that I have about IDE drives is that they tend to be slightly less reliable (cost-reduced), and that is likely the reason for the lower price. If I had my druthers, I would prefer having 8/9GB Cheetah drives, and a few other types for testing, using a couple of 3940 controllers to spread the load. I would also like to have an 8 processor Pentium-pro motherboard, to get my kernel compile times down from 90secs to 25secs :-). BTW, my kernel compile time of approx 90-100secs is when using IDE drives in an SMP environment. :-). John
