This server will be mirroring, so we wouldn't need XOR. It'd
be a big plus for RAID 5, though.
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.
