I was under the impression that the promise cards actually offloaded  
some of the work, but I guess that can only happen with raid cards  
that present one disc to the OS.

Definately has potential.
I think I might first focus on a motherboard that has a well supported  
IO chipset.  If I can get over 200Mb accross the whole array then I'll  
be happy.

After that I will look at a decent quality raid card.
