I believe, that a "dd bs=128k count=1000 of=/dev/null" (maybe with
several iseek values) would be sufficient to detect the worst
That test should be done on at least one box (always the same if
possible), whenever a hard disc is changed (then the box has
changed a little bit), and whenever there is a new release or some
