=== File systems optimized for flash memory, solid state media ===
{{Main article|Flash file system}}

Solid state media, such as [[flash memory]], are similar to disks in their interfaces, but have different problems. At low level, they require special handling such as [[wear leveling]] and different [[error detection and correction]] algorithms. Typically a device such as a [[solid-state drive]] handles such operations internally and therefore a regular file system can be used. However, for certain specialized installations (embedded systems, industrial applications) a file system optimized for plain flash memory is advantageous.

* [[NOVA (filesystem)|NOVA]] – the "non-volatile memory accelerated" file system for persistent main memory.
* [[One File System|OneFS]] – a filesystem utilized by [[Isilon Systems|Isilon]]. It supports selective placement of meta-data directly onto flash SSD.
* [https://www.tuxera.com/products/reliance-velocity-flash-file-system/ Reliance Velocity] - a proprietary flash file system by [[Tuxera]] with high resilience (fail-safe technology) and built-in data integrity. This file system is best suited for embedded applications requiring heavy data workloads over long-term operations. Reliance Velocity can used for all block based media like [[MultiMediaCard|eMMC]], [[Universal Flash Storage|UFS]], eSD, [[SD card]], [[CompactFlash|CF card]], and [[Solid-state drive|SSD]]. It is compatible for [[Linux]], [[Android (operating system)|Android]] and [[QNX]] with portability to other embedded operating systems.
* [https://www.tuxera.com/products/reliance-edge/ Reliance Edge] - a proprietary file system by [[Tuxera]] for resource-constrained embedded systems. It has built-in [[data integrity]] with [[copy-on-write]] transactional technology and [[Deterministic algorithm|deterministic]] operations. This file system can be used for block based media and is configurable for Small [[POSIX]], Full POSIX and can be ported to many [[Real-time operating system|RTOS]] environments. Tuxera has a certified version of this file system called [https://www.tuxera.com/products/reliance-assure/ Reliance Assure]. The source code of Reliance Assure is complaint to [[MISRA C]] and developed following the [[Automotive SPICE|ASPICE]] framework.
* [[Segger Microcontroller Systems]] emFile – filesystem for deeply embedded applications which supports both NAND and NOR flash.  Wear leveling, fast read and write, and very low RAM usage.
* [[SPIFFS]] – SPI Flash File System, a wear-leveling filesystem intended for small NOR flash devices.
