The IT8212 is not a fake raid card - it depends on the firmware whether you see a drive per raid volume (hardware raid mode) or not (ATAPI capable firmware). We've found the raid firmware seems quite temperamental and there is little performance gain from raid 1 in hardware over software so using md or device mapper is recommended for that reason.
