True!
And supposedly Widnows implementation of raid is good too.

I was actually referring to the performance of the overall system, since the CPU is now in charge of RAID as well as all the rest. On the other hand, I personally never spent time in finding out how much more resources would be devoted to that, and by simply looking at it, the small server I referred to in my previous post does not seem to show any more CPU time devoted to disk management. It's not a heavily used server, though, so I don't know how it would behave under stress...
