For a newsfeed spool it's not overkill at all.  Those things eat I/O.
He would definitely benefit from raid0 striping.  There is however
little point in adding in other raid levels since newsfeed data is
considered expendable.  The only issue might be the amount of CPU cycles
he might lose, raid0 doesn't eat that many, but we are talking about an
IPC here with 25Mhz sun4c.
