Did you read what I wrote ?

notice "suspects" ?

It would be entirely reasonable for the driver to suspect all drives
larger than some N GB to be 4k drives.

But the information has to flow up from the driver, so that
intermediate GEOM classes can adjust the two stripe-properties
according to what they do.
