List of log-structured file system implementations.

Some kinds of storage media, such as flash memory and CD-RW, slowly degrade as they are written to and have a limited number of erase/write cycles at any one location. Log-structured file systems are sometimes used on these media because they make fewer in-place writes and thus prolong the life of the device by wear leveling. The more common such file systems include:

  • UDF is a file system commonly used on optical discs.
  • JFFS and its successor JFFS2 are simple Linux file systems intended for raw flash-based devices.
  • UBIFS is a filesystem for raw NAND flash media and also intended to replace JFFS2.
  • LogFS is a scalable flash filesystem for Linux that works on both raw flash media and block devices, intended to replace JFFS2.
  • YAFFS is a raw NAND flash-specific file system for many operating systems (including Linux).
  • F2FS is a new file system designed for the NAND flash memory-based storage devices on Linux.
