== Example: embedded Linux system equipped with a raw NAND flash memory and UBIFS file system ==
There's are two main indicator indicators of NAND device health:
* current ECC corrected errors
* block erase counter.

As a confirmirmation confirmation of this data, the maximum EC of a given UBI partition can be read directly from <code>sysfs</code>:<syntaxhighlight lang="text">

</syntaxhighlight>
== Example: embedded Linux system equipped with an e.MMC ==Regardless of the file system used, e.MMC devices provide some functionalities conceived to monitor their health status while operating. As these functionalities are defined by [https://www.jedec.org/sites/default/files/docs/JESD84-B51.pdf JEDEC standards], all the vendors implement them. TBD = References ==
