It is correct that flash memory has a limit to how many times each physical location can be written, but there is no limit to the number of reads. Most modern thumb drives and flash cards have intelligent controllers that will relocate memory as needed so that the limit is never exceeded. However Smart Media is an older standard without an internal controller. In this case it is up to the device (keyboard, camera etc.) to assure that the write limit is not exceeded. This makes Smart Media a little more unreliable than other types of memory cards. Always back up your flash memory!

Kind regards,
