I'd suggest using the UUIDs for the disks (acquired via the blkid command) and adding them to your /etc/fstab ... That's always been my solution to commonly-connected-but-never-permanently external disks. It won't ensure the same sd* name, but it will ensure that they get mounted consistently where you expect them to be.
