I'm guessing that what Heinz means is that dmraid reads superblocks or
whatever in accordance with the sector size on the hardware itself
("hard" = hardware level); since it does this in order to feed the
correct setup info to device-mapper it would not be acting on virtual
devices..

Just my interpretation though, please correct me if i'm wrong.
