    I am not going to take a stand on performance other then to say to
    both parties:  prove your points.  I personally believe that features
    and management characteristics are better comparison points between
    software and hardware RAID systems.  Performance is and always will be
    a moving target.

    But I will interject one point of interest, and that is the cost factor.
    As a friend of mine pointed out to me a few days ago, the cost of
    RAID hardware has dropped precipitously over the last 5 years.  It is
    cheap enough now that one might as well just use it on multi-disk
    servers.  Hopefully this will result in more and better drive support
    in FreeBSD, I sometimes get the feeling that we've dropped behind
    in that area.
