700 is the minimum block-size. The block-size has always been dynamic,
but it was not a very good value for really large files in 2.5.7 and
prior because it maxxed out at 16K blocks. Beginning in 2.6.0, the
block-size started being picked according to a square-root-of-size
heuristic that allowed for much larger block-sizes.
