It doesn't matter if it writes to the same place or not, it's the number of writes that matters - the writes are wear-levelled over the card so there's no difference if you re-write the same VFAT block or not (not taking into account possible wear-levelling sectioning of the card, which is up to the vendor).

Maybe that's what you meant anyway, just thought I should mention it to avoid confusion.
