Chevrolux, can FreeNAS do what I said, with some disks RAIDed and some not?
...
ZFS will allow you to do this so I would expect that you can on a FreeNAS box even if you need to do some of the setup outside of the friendly gui.
You would create two ZFS pools, one raided and another not and then put a file system on each pool.
