```suggestion
didn't need to be erased. Which means the physical chip will wear out
faster.

This new option sets the maximum % of memory that is allowed for
redundant erase. Default is 0, S+1 size block only selected if all the
area needs to be erased in full. 50 means that if more than a half of
the area needs to be erased, a S+1 size block can be selected to cover
the entire area with one block.
