"Flash memory, regardless of format, supports only a limited number of 
erase/write cycles before a particular "sector" can no longer be 
written. Memory specifications generally allow 10,000[1] to 1,000,000 
write cycles. Typically the controller in a CompactFlash attempts to 
prevent premature wearout of a sector by mapping the writes to various 
other sectors in the card - a process referred to as wear levelling."
