Flash cards memory write cycles limitations?

Flash cards have a limited number of write cycles per area of the memory (cells). While this may be very high, for the time being, assume I'm going to use them up at some point. [MI]
Am I better off leaving data on the card to force new data to be written to a different area proactively, or will the card take care of evenly spacing new data to a least-written part (possibly the same controller that handles not writing to the dead parts when they do eventually wear out).

Best answer: There's also the whole FAT issue to consider. Any change anywhere on the flash will also require a change in the file allocation table, which is written in one particular location. Although the wear leveling may help in this case, since the FAT is relatively small and the blocks are relatively large (at least in that Sandisk whitepaper.)
