People went back and forth on the list saying that if a hardware  
controller was out of the budget right now RAID 10 would be the best  
solution.

It seems that the installer wont let you create two RAID1 with the  
same mount-pount and it looks like you have to specify one. I dont see  
how to do this and I dont know how to make a custom installer for this.
