If I use "top" I can see what CPU is busy and what process is using all of my CPU.

If I use "iostat -x" I can see what drive is busy.

But how do I see what process is using all of the drive's throughput?

You're looking for iotop (assuming you've got kernel >2.6.20 and Python 2.5). Failing that, you're looking into hooking into the filesystem. I recommend the former.
