You would do much better with a processor upgrade than a hardware raid
card that can save you a few % CPU usage. I mean I have been running
software raid at work for years (I have 10 TB to 15 TB raid 5 + 6 )
and the CPU usage for the raid on my servers/desktops (some 4 year old
2GHz Opterons) rarely goes above 7% unless the array is rebuilding
which only happens if you need to replace a drive.
