Preserving Your SD And MMC Flash Memory Cards
Unlike the hard disk, flash memory has a limit, albeit a high one, on how many times it can be written to. Directly related, did you know every time you take a picture with your digital camera, several write operations are performed on you memory card?
While digital camera writes are normal operations, there are a few things you can do to keep the number of write operations performed on you flash cards down:
* Try to use flash memory cards only for storing data, but never modifying it. For example, if you edit pictures or music files, copy the file to your hard disk, do your changes and then write it back to your memory card.
* Delete the data on the flash card only if the storage medium is filled up and cannot store new data anymore. This ensures write operations are performed on different sectors and not the same sectors over and over again.
While it is not essential to follow the above tips (flash memory is pretty cheap), it is just something to keep in mind to help preserve the life of your memory card.
