Berkeley Fast File System

The Berkeley Fast File System (FFS) is an improved way of organizing and storing data on a disk, making file access faster and more efficient. It divides data into blocks and groups related information together, reducing the time needed to read or write files. FFS also includes features like better handling of disk space, protecting against corruption, and optimizing performance with smarter caching. Overall, it enhances the speed, reliability, and scalability of file storage for operating systems like BSD Unix.
