SD cards are not hard drives. From what I have heard/read, they have limits on
the number of times data can be written to them before you will wear them out.
Writing to an SD card will usually require the need to update the directory
information so that portion of the device can wear out faster. If the
directory area gets worn out, you will run in to all kinds of problems
accessing your data.
A rethink of how you are using the SD memory card would be in order. If you
provide some information on what it is you are trying to do, others on the
list may be able to offer better ways of storing the data.
