Don't forget that you don't have to do the same thing (ie one big
array) with the whole drive. You can partition the disks, and then
built arrays with the partitions (as mentioned before). So you could
have a small boot volume that's mirrored across all the drives, a
system volume that's RAID6 across all the drives, and separate
unraided drives for Myth storage. Just for example.
That's something Linux can do, that many (most ?) hardware raid
controllers don't support.
