We use five 300GB SSD volumes:

        -h classic,524287
        -p between_bytes_timeout 15s
        -p cache_vbe_conns on
        -p cli_buffer 32768
        -p default_grace 0s
        -p default_ttl 0s
        -p err_ttl 0s
        -p first_byte_timeout 15s
        -p listen_depth 8192
        -p lru_interval 3600
        -p max_restarts 2
        -p pipe_timeout 15s
        -p purge_dups on
        -p rush_exponent 32
        -p sess_timeout 15s
        -p thread_pools 8
        -p thread_pool_min 32
        -p thread_pool_max 8192
        -p thread_pool_stack 262144
        -s persistent,/cache/sdb/varnish,240G
        -s persistent,/cache/sdc/varnish,240G
        -s persistent,/cache/sdd/varnish,240G
        -s persistent,/cache/sde/varnish,240G
        -s persistent,/cache/sdf/varnish,240G

I'm /pretty/ sure I also tested with a single -s option, but I (embarrassingly) 
may not have.

Yeah, those tests look solid.  I'll run the tests when I'm back at my build 
machine.

Thanks,
