Later Berkeley Fast File System also called BSD Fast File System FFS was used in Unixes which is not the same as UFS. It presents the motivations for the changes the methods used to effect these changes the rationale behind the design decisions and a description of the new implementation. This paper describes the changes from the original 512-byte UNIX file system to file the new system released with the 42 Berkeley Software Distribution.
This paper introduced techniques to make the file system disk aware thus demonstrating the importance of understanding the. Although the free list was initially ordered for optimal access it quickly became scrambled as files were created and removed. An earlier Berkeley implementation made some improvements but was still inefficient using only about 4 percent of the potential speed of the disk drives.
