These are not very usefull tests of raw disk bandwith because they use
the filesystem (and are hence subject to the vagiaries of block
allocation, etc) and are not likely to be very repeatable or
comparable. Nore are the big enough or long enough to reduce the
variance of the result or cover one-off spikes (e.g. what if it is
running just when a cron job happens to kick off?)
