To maximize random write performance, SanDisk developed the ExtremeFFS flash file management system. This operates on a page-based algorithm, which means there is no fixed coupling between physical and logical location. When a sector of data is written, the SSD puts it where it is most convenient and efficient. The result is an improvement in random write performance – by up to 100 times – as well as in overall endurance.[Far East Gizmos]
SanDisk has developed a new file system for flash-based SSD drives, improving random write speeds by up to 100 times. The system, dubbed ExtremeFFS, should be coming to products sometime next year. How's it work?
