i personally like shimon's st.d...
it exercises a disk very thoroughly, so if you want to benchmark - and,
of course, have plenty of time for the box to run the benchmark - st.d
is the choice since you got your free-of-charge(tm) burn in of the disk
subsystem with it. what it basically does is simulating a nonlinear load
behaviour like you got in a multi-client or large amount of concurrent
i/o processes environment and i like it a lot. welps, i won't argue
about the command line parameters - just see for yourself ;-)
