Doesn't the same argument apply here as well that was made a while ago
on this list about the Promise IDE RAID controller cards, namely that
these devices are not doing any hardware RAID at all, but rather using
the host CPU to do their parity calculations? I have no idea at this
point whether this is the case or not, what makes me pause though is
that 3WARE nowhere makes any claims to do HW RAID. If true, this would
make these controllers look much less of a great deal, as you're
basically paying for what you can also get for free with Linux SW RAID.
