SanDisk Bows Flash File System

LOS ANGELES -- SanDisk Corporation (NASDAQ:SNDK) 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.

Speaking in Los Angeles at WinHEC 2008, Rich Heye, senior vice president and general manager for SanDisk’s Solid-State Drive (SSD) Business Unit, presented ExtremeFFS along with two metrics – vRPM and LDE – that can help end-users evaluate SSDs. vRPM enables comparisons in performance between an SSD and a hard disk drive (HDD) or another SSD, and LDE calculates the lifespan of a solid-state drive.

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, he said. “SSDs will revolutionize client storage, but we need new benchmarks that allow them to be treated differently than HDDs.”
