You should be able to do that, because (software) RAID configuration
happens on a per-partition basis.  That is, you specify which
partitions and what type of RAID you want for each RAID device.  Just
make sure you use the Linux RAID driver and not the "RAID" built in to
the motherboard, because the latter is significantly less capable, and
often slower as well.
