Sysstat shows the busiest disk only, which probably means that you might have a hotspot in your raid, or the most active blocks accidentally are on one disk.
Not necessarily somthing to worry about right now, but it is something to look further into, since it might cause problems if the hotspot warms up a little more :)
statit and perfstat are your friends in this case, to find out why the IO on at least one disk is high.

You just need to keep an eye on how long you run these tools. Are there certain peak time or is this consistent 24 hours? I'm surprised that you are not getting calls on performance issues.
