About this title

Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A flash file system is a file system designed for storing files on flash memory devices. These are becoming more prevalent as the number of mobile devices is increasing, the cost per memory size decreases, and the capacity of flash memories increases. While a block device layer can emulate a disk drive so that a disk file system can be used on a flash device, this is suboptimal for several reasons: Erasing blocks: Flash memory blocks have to be explicitly erased before they can be written to. The time taken to erase blocks can be significant, thus it is beneficial to erase unused blocks while the device is idle. Random access: Disk file systems are optimized to avoid disk seeks whenever possible, due to the high cost of seeking. Flash memory devices impose no seek latency. Wear leveling: Flash memory devices tend to wear out when a single block is repeatedly overwritten; flash file systems are designed to spread out writes evenly. Log-structured file systems have all the desirable properties for a flash file system. Such file systems include JFFS2 and YAFFS.
