Why 4K is almost lifetime of my eraseblock? the specs says 10K,
how you result that number 4?
How to set the WL threshold? any equation?
When eraseblock counter exceed 2*WL threshold, it will be less
used, move its data to seldom used eraseblock?
Why WL can't just simply pick up the min used PEB to be the
next block to use?
