iotop (dtrace?)

I've got two systems with a constantly high rate of disk I/O that sometimes seems to be overwhelmed from it. Before trying to decide if a hardware upgrade will help, I'd like to figure out which processes generate the load.
I've found a couple scripts named iotop which appear to produce what I would be interested in, but they appear to require Solaris or Linux.
Has someone ported over one of them, or would have a suggestion how to go about writing a custom dtrace script to gather this kind of information?
I can successfully run a couple of sample dtrace scripts on these 8-stable amd64 boxes.
Thanks,
Stefan
