Berkeley Fast File System
In computing, the Berkeley Fast File System (or FFS) is a file system used mostly by BSD-derivative Unix variants. It is a distant descendant of the original filesystem used by Unix System V (called just 'FS'). FFS sits on top of UFS (1 or 2) and provides directory structure information, and a variety of disk access optimizations. UFS (and UFS2) define on-disk data layout.
