You mention that you chose data=journal, i.e. full journaling. Have you
tried ordered mode as well? This should still yield a significant
performance win because of reduced head movement and faster metadata
writes. It may or may not be faster depending on the size of the
written data itself..I'm just curious if you tested this.
