JFS

Resources

Wikipedia

JFS (Journaled File System) 是一个由 IBM 创造的 64 位日志文件系统. An implementation for the Linux kernel is available as free software under the terms of the GNU General Public License. It is low on resource usage and comparatively fast doing all kinds of filesystem operations (as opposed to being specialized in some, e.g. XFS is fast with big files, but slower with small ones). As such JFS is especially good for usage with battery-powered devices such as laptops.
