IMPORTANT
The life expectancy of nonvolatile media is dependent on the number of write
cycles that are performed. Nonvolatile media use a wear leveling technique, or
technology for prolonging the service life, but avoid frequent writes.
Avoid frequent writes when logging data. We recommend that you log data to
a buffer in the memory of your controller and limit the number of times data is
written to removable media.
