        Hello.  My suggestion is to check the performance, if possible, of a
hardware raid card versus raidframe in a given eenvironment.  The reason is
that I've run into a number of situations where raidframe out performs
hardware raid cards by a good margin, and this was somewhat of a surprise
until I started asking around, and found that, in fact, my experience
wasn't that unique.  In fact, I think if you google around for hardware
raid versus software raid, you'll find quite a few people hav had the
experience that I have.
