High Quality Content by WIKIPEDIA articles! The Unix file system (UFS) is a file system used by many Unix and Unix-like operating systems. It is also called the Berkeley Fast File System, the BSD Fast File System or FFS. It is a distant descendant of the original filesystem used by Version 7 Unix.Early versions of Unix filesystems were referred to simply as FS. FS only included the boot block, superblock, a clump of inodes, and the data blocks. This worked well for the small disks early Unixes were designed for, but as technology advanced and disks got larger, moving the head back and forth between the clump of inodes and the data blocks they referred to caused thrashing. Marshall Kirk McKusick, then a Berkeley graduate student, optimized this for 4.2BSD's FFS (Fast File System) by inventing cylinder groups. This breaks the disk up into smaller chunks, each with its own inode clump and data blocks.
