SanDisk has unveiled ExtremeFFS, an advanced flash file system for solid-state drives (SSDs) that yields dramatic improvement in performance and reliability for computing applications. Sandisk says this patented flash management system has the potential to accelerate random write speeds by up to 100 times over existing systems.
ExtremeFFS 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, resulting in an improvement in random write performance - by up to 100 times.
ExtremeFFS incorporates a fully non-blocking architecture in which all of the NAND channels can behave independently. Another key element of ExtremeFFS is usage-based content localization, which allowing it to ‘learn’ user patterns and dynamically writes and alters the position of data to maximize the product’s performance and endurance.
The company expects the SSD net performance next year will be four times faster than the current generation of SSDs and nearly six times that of the latest 2.5-inch HDDs.
