It could be an interaction with the erasable-block size of the
flash.

Flash doesn't like small writes, and 120KiB could be small and inefficient
for a 256 KiB flash block.

I have a really slow flash (writes at 2MiB/s), so I tried to increase the
number; the trick was impossible for me, the parameter is refused when >120.
