Software Raid is better, you have more control over things.  Right now
I'm fighting a HW Raid controller on a Sun box which will only rebuild
one mirror pair at a time, even if I don't care what impact that will
have on my data access, since my data is toast right now anyway.  

With software raid, I can do rebuilds as fast as my CPU can
controllers can push the data, which is alot faster than currently.

In their time, HW RAID was a good idea.  These days, Moore's law has
caught up with such a vengeance that it's not worth doing anymore.
