The standard filesystem supported by the Linux kernel. The ext3 filesystem adds a “journal” to the ext2 filesystem allowing a fast consistency check after a machine crash. ext3 is available in the linux 2.4.x series kernel and backwards compatible so you can mount an ext3 filesystem as ext2. The ext2 and ext3 filesystems have a good reputation for stability and performance although there may be faster alternatives for certain applications like the ReiserFS filesystem.
