I've done similar mixes of SATA, IDE, SCSI, etc., etc. in legacy 
systems. Beware of the BIOS selecting SCSI or SATA first, and beware of 
the re-ordering of reported devices on the "SCSI" chain while adding or 
disabling SATA drives. Using partition labels and LVM instead of 
hard-coding your mountpoints as /dev/sda1, /dev/sdb2, etc. can be vrey 
helpful.
