I don't know about the Highpoint (my 1820a is used as a jbod  
controller only -- the only one I could find that was low profile :-)  
but some better RAID controllers do the mirroring in HW as well -- no  
software drives the RAID functions.  My adaptec 2100S 2200S 2410A all  
do it this way, which I greatly prefer.  I like the "complexity" of  
the RAID completely hidden from the OS.
