...just as you would when you wouldn't have raid-1 but just a single drive 
with multiple partitions.  And that is a very common and sensible thing to 
do, especially on production servers!  People who run /usr, /var, /home all 
off the single / filesystem aren't taking due diligence when it comes to 
security IMO.  
That this may degrade performance may very well be, but it doesn't make having 
seperate partitions any less desired / needed in a production environment.
