It would be interesting to see the output from your "bbgen" column if you run bbgen with the "--report" option.
I haven't seen bbgen do very much I/O. Sure, you're generating 8x2 MB of data per minute, but most disk today will easily deliver 10 mbit/sec throughput. And it's not random access, just sequential writing of a single file.
I'd be more inclined to think it's your RRD file updates that are responsible for the disk I/O you see. Try disabling the [rrddata] and [rrdstatus] tasks in hobbitlaunch.cfg and see if the iowait drops.

No.
