Also note that some RAID-1 controllers don't do load balancing
(especially those "trick BIOS" ones that are really doing it in
software), and aren't any faster. Even many software RAID-1
implementations are limited in what they can do because it is done at
the CPU instead of at the ASIC or microcontroller. 3Ware seems to have
best RAID-1 implementation in this case (see StorageReview.COM for
tests).
