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.
