"some of the above" :)   The reads will typically be done from 
whatever component RAIDframe figures it can get the data from the 
fastest.  It esitmates this by simply selecting the component that 
has the shortest I/O disk queue at the time of the I/O.  
See: rf_dagutils.c:rf_SelectMirrorDiskIdle() for the gory details.
