Just checked the Seagate manuals. One disk can handle up
to about 350 physical I/O per second. So you can calculate
what you can expect on heavy load, depending on caching
of the controller + read caching of IBM i host and then try
to find out how fast a little set of these disks will raise up
to 80% usage (aka: high latency times) when the
guest LPARs try to do some work...
