        Richard - Not really.  Optimal performance derives from spreading
the
                  I/O load over multiple db volumes (multiple TSM threads)
        and multiple real I/O paths - as well as keeping as much as possible
        in real memory.  Many of us use relatively low capacity disks in
        quantity to increase the number of disk arms doing writing, to
        minimize seeks and rotational delays.
