Consider that the poor little controller chip on the raid card is 
vastly underpowered for what you are asking it to do in raw IO speed 
plus handling all the raid calculations. Compare that to the excess 
number crunching capacity of your primary cpu + mmx processor (used 
for raid parity calculations) and you might find software raid to be 
a significant improvement if you can get the controller to just
concentrate on delivering raw IO to the dma of your main machine.
