F2FS - A New File System for Flash Storage

F2FS - A New File System for Flash Storage

Explore the design and performance of F2FS, a Linux file system optimized for flash storage devices, in this 26-minute conference talk from USENIX FAST '15. Delve into the key features, structure, and algorithms that enable F2FS to outperform EXT4 on both mobile and server systems. Learn about append-only logging, adaptive logging, and the cleaning procedure tailored for flash storage characteristics. Discover how F2FS reduces elapsed time in realistic workloads by up to 40% and achieves significant performance improvements in synthetic benchmarks. Gain insights into data separation techniques, cleaning costs, and the fsync overhead reduction strategies employed by F2FS.
