For best performance, I'd go with an AHA-29160 or 39160.  The 29160 is a
particularly good idea if you plan on having them share the bus with
slower devices, because it can segment the bus by speed instead of
slowing everything down to what the slowest device on the bus can
handle.  However, the cost of a 29160 might not be cost-effective for
you if you don't have one on hand.

I wonder what sort of controllers Buslogic would be producing now if
Mylex hadn't bought them out and basically killed them off.  Their
controllers were screamingly fast.
