Right, I was wondering if we could try to persuade the Manufacturers to
advertise a more meaningful optimal I/O size ...  But as you say, the
pressure is coming from applications and filesystems for larger block
sizes and that will create I/O patterns that are more beneficial to the
underlying device hardware regardless of whether it actually tells us
anything about what it would like.
