-If you wish to write data to the same disk as OpenWrt is installed on, an ext4 filesystem with write persistence is useful. If using an mSATA SSD, the JFFS2 filesystem ​which is writable, ​has journaling and wear leveling may be preferable but will have to be built as OpenWrt does not auto-generate JFFS2 images.
