flash drives can fail quickly especially if used a lot.


Indeed the life of FLASH memory cells is limited. They are good for an
average of 1000 erase/write cycles. However, one problem is that they are
not byte eraseable, they are only block eraseable. So changing one byte in
a file requires the whole memory block to be erased and then rewritten.
FLASH memory is able to handle all of this internally with the user being
unaware what is going on. The memory also ensures that the memory blocks
are used rotationally so that one block doesn't get used more than any
other.

But the main point is that that 1000 cycles is an average - some last longer
and some shorter, with the occasional one lasting a very short life.
