Why do you say hardware raid frees up "a lot of CPU time?"  Have you
measured this?

Do you have any servers that are cpu-bound instead of io-bound?

I am having this exact discussion with my business partner at the
moment--he is also a proponent of hardware raid.  I don't see the big
win in hardware raid.

I should probably search the archives, I sure this topic has been
covered in detail before ...
