I think there may be differences in controllers and possibly in failure 
modes as to whether the 2nd drive becomes seen as the first when the 
first one fails.  But I'm not sure how to know this ahead of time or the 
right syntax to use for each case.  And while the md devices will still 
build out of the right pieces when they autodetect, you may also need to 
adjust anything that uses the /dev/sd? names to account for them 
shifting (or not) and be aware of it in any manual setup commands like 
using mdadm to force partitions to be added if they didn't come up
