Reiser file system
ReiserFS (Reiser File System) is a journaling file system for Linux. ReiserFS is known to be particulary good at handling the large numbers of small files. It is the default file system on a number of distributions, including: Elive, Xandros, Linspire, and GoboLinux.
ReiserFS supports filenames up to 4032 bytes, maximum file size of up to 8 TB, and file system of up to 16 TB.
ReiserFS development has slowed because of the legal problems of Hans Reiser, its creator.
