Don't.  Use a russian doll setup instead.

Scale your disks the following way (the ones you have already):

smallest disk is in the most-used machine.  disk images (backups) of  
work are then 'imaged' into the next-largest disks, then the next,  
then the next, etc. through the use of your filesystem.

RAID is an expensive band-aid.  if your smallest disk is your most- 
used one, then it becomes easier and easier to keep your own backup  
scheme working - on whatever disks you choose to add to your setup.   
remember: russian doll means you can be as *absolutely* safe as you  
add disks, one by one, to your collection.
