measuring tape IO speed

since iostat doesn't allow the option of measuring IO speeds to a tape
device - how can it be measured.

I'm looking to indepedantly test IO performance - so the possibility of
using dd is limited. One option is to

dd if=/dev/zero of=/dev/tape/tape0 count=5000 bs=128k

or if=/dev/random, then workout the transfer rate per second, however would
like the same kind of output as iostat.



thanks,
Kevin
