A hardware RAID controller can write to each disk in parallel, computing the necessary checksums, etc., while a JBOD with a single controller will need to write to each disk separately (if the data is to span multiple disks).
Is this still true with SATA? As I understand it every SATA channel has its own controller. I seem to recall that the cpu can just issue commands to each of these controllers and move on.
