I do not really care as the percieved perfomance when I use it for its intended purpose is fine but I would like to have a better understanding of what is going on in there.
I am using HDTUNE trial version. Also what kind of array are you running as it will depend greatly. a Raid 1, 0 or 10 will have almost not cpu load in a software raid setup as there is no parity calculate but a raid 5 or 6 will as it has to calculate parity.
and now for something completely different
