SanDisk ExtremeFFS accelerates SSD random write speeds by up to 100 times over existing systems

SanDisk today unveiled an advanced flash file system for solid-state drives (SSDs) that yields dramatic improvement in performance and reliability for computing applications. Called ExtremeFFS, this next-generation patented flash management system – which has the potential to accelerate random write speeds by up to 100 times over existing systems – will ship in SanDisk products during 2009. For SSDs to perform optimally in Windows Vista, and thus replicate or surpass the functionality of hard disk drives, a new flash management technology is needed to accelerate SSD write speed and endurance.

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.
