[[USB stick]]s, [[MultiMediaCard|MMC]]s, [[Secure Digital|SD]]s, [[CompactFlash]]es and other popular removable devices should not be confused with MTDs. Although they contain flash memory, this is hidden behind a [[block device]] interface using a [[Flash Translation Layer]].<ref>{{cite web | url=http://www.linux-mtd.infradead.org/doc/general.html#L_overview | title=Memory Technology Device Overview | accessdate=1 September 2012}}</ref>

When using an MTD, the use of an MTD aware file system such as [[JFFS2]] or [[YAFFS]] is recommended. The MTD subsystem exports block devices as well, which allows the use of common filesystem like ext4. However, using an MTD this way is not recommended since there is neither detenordetection of bad blocks nor any kind of wear leveling.
