The wear-levelling only makes all erase blocks/chunks/... wear out at the same rate (at least more or less). It doesn't avoid or reduce wearing out, it just distributes it. Even if you do it: Make sure you have the better flash chips, not the cheap ones with only 5000 (or so) write cycles. Or even MLCs ....
