Imprimis would disable the Quantum cache for the obvious reason: disabling
the cache causes worse performance.  If they also disable the cache on
the Wren, then the comparison of the two drives is interesting.  For a
real comparision, one would have to also test with both caches enabled,
since that is the normal situation, but then one gets into nasty issues
of trying to simulate real usage, and it gets to be a big mess.

If they leave their own cache enabled while disabling the Quantum cache,
then their data is garbage.

Does the Wren have a cache, by the way?  The marketing stuff I've got on
the Wren doesn't mention a cache, but in the produce specification, I
see that they have a mode select page for controlling cache parameters.
