Yes, e.g. during development/loop testing we need to flash a new system 
on an MTD partition.
The (UBIFS) system could be tiny but the partition large in which case 
the erase time becomes even more significant.
Even in more usual cases of reflashing a bigger system this gives ca. 5 
% speed improvement.
