If you are doing raid, once the partitions are set up you will only
see /dev/md? device names except in madam commands or when looking at
/proc/mdstat. And you can move the drives around later so the actual
device names would be different without affecting the  md assemblies.
 I think you are being a little picky....  You could always move the
controller cables around, but I'm not sure there is any guarantee that
the drives will be detected in the same order every time.
