NAND flash storage device performance in Linux file system

To enhance reliability of the Linux file system, a new technique for disk storage management called a log-structured file system for the Sprite operating system was presented. A log-structured file system writes all modifications to disk sequentially in a log-like structure, thereby speeding up both file writing and crash recovery. Presently, NILFS, BTRFS and Ext4 are the most striking Linux file systems; each of them has its own characteristics, represents a different design and development of Linux file system. This paper measures the performance of NILFS2 comparing with EXT3 and EXT4 file systems by using SSDs in Linux file system.
