Extreme Flash File System (ExtremeFFS) Make SSD More Popular

Recently SanDisk the leading Flash Drive manufacturer announced a new filesystem, ExtremeFFS for Solid State Drives (SSD). SSDs are more reliable and durable , now it is more faster. SanDisk explained its new file system technology for SSDs, which it calls the ExtremeFFS, will boost 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.
ExtremeFFS incorporates a fully non-blocking architecture in which all of the NAND channels of SSD can behave independently, simultanius read and write is posible. Another key element of ExtremeFFS is usage-based content localization, which allows the advanced flash management system to "learn" user patterns and over time localize data to maximize the product’s performance and endurance.”

Senior vice president and general manager of SanDisk’s SSD Business Unit Rich Heye said, “This feature might not show up in benchmarks, but we believe it is the right thing to do for end-users.” He says ExtremeFFS are expected to ship in 2009.
