I used RaidZ with 4x5 disk and 4x6 disk vdevs in one pool with two hot
spares. This is very similar to how the pre-installed OS shipped from sun.
Also note that I am using ssh as the transfer method.

I have not tried mbuffer with this configuration as in testing with initial
home directories of ~14GB in size it was not needed.

This configuration seems to be similar to Carsten Aulbert's evaluation,
without mbuffer in the pipe.
