SPIFFS is a wear-leveled file system for SPI NOR flash devices on embedded targets, written in C. It is designed for small microcontroller targets with sparse RAM, using statically sized buffers and a POSIX-like file API.
Use cases
- store files on SPI NOR flash in an embedded project
- add a file system to a microcontroller with little RAM
- wear-level flash writes on an ESP8266 or similar chip
- read and write config files on embedded flash
- mount a flat file system on NOR flash without directories
When to choose
- you need a small-footprint file system for SPI NOR flash on an MCU
- RAM is scarce and you need statically sized buffers
- you need wear leveling and consistency checks on flash
- your storage is under ~128MB and a flat file namespace is acceptable
When to avoid
- you need directories or hierarchical paths
- you need real-time write latency guarantees
- your flash is larger than ~128MB or has bad blocks needing management
- you need a filesystem maintained with active new development
