It will depend on what kind of test you are running. Anything
that calls fsync() is going to be fairly horrible for HAMMER...
flushing the filesystem is very expensive and going to remain
that way for a while.
Normal sequential write I/O without fsync() should be fairly close
to platter rates, at least that is what I get, e.g. with something
like dd.
