Actually, hardware RAID typically runs something called firmware (which
is technically software, though it tends to be a little more difficult
to alter) and offloads the task of balancing the data across multiple
disks off the CPU.  This is the primary difference between software RAID
(which, since it uses the CPU, reduces the available CPU for other
tasks) and hardware RAID.

That's a gross oversimplification without consideration of a particular
setup.
