In my limited testing, 6 drives for WAL would be complete overkill in
almost any case. The only example I've ever seen where WAL was able
to swamp 2 drives was the DBT testing that Mark Wong was doing at
OSDL; the only reason that was the case is because he had somewhere
around 70 data drives. I suppose an entirely in-memory database might
be able to swamp a 2 drive WAL as well.
