The Flash File System (FFS) is a specialized file system designed to manage data stored on flash memory devices, such as USB drives and solid-state drives (SSDs). Unlike traditional hard drives, flash memory has unique characteristics, including limited write cycles and faster read speeds. FFS optimizes data storage and retrieval to enhance performance and longevity of the flash media. FFS employs techniques like wear leveling, which distributes write and erase cycles evenly across the memory, preventing premature wear of specific areas. It also uses data structures that minimize write amplification, ensuring efficient use of available storage space. This makes FFS suitable for applications requiring high reliability and speed.
