heh.. Excellent point.
My point was that you could get away with a smaller setup (number of
disks) if it doesn't have to deal with reads and writes are not time
dependent than you will if you attempt to pull 500MB/sec off the disks.
If it is foreseeable that the database can be held in Ram, that it is
much easier and cheaper way to get high IO than with physical disks.
