Network throughput for an Oracle database : Smaller number of large PIOPS volumes or large number of smaller PIOPS volumes

Individual 4000 PIOP volumes at 16K  I/O's can theoretically transfer 64MB/s.  Smaller PIOP volumes (e.g 1000) can burst up to 40MB/s.   In this case, especially for bursty workloads, it may be more cost effective to use smaller PIOPS volumes (but more of them) in a raid0 configuration, than to use fewer higher rated PIOPS volumes.
