Now in its third generation of solid state drives (SSDs), SanDisk says its new G3 series qualifies as the world's fastest multi-level cell (MLC) based SSDs, equating the performance to that of a theoretical 40K RPM hard drive. That's a big claim considering that, for the most part, SSDs have thus far failed to push real-world performance boundaries.
SanDisk rates the G3 series at 200MB/s read and 140MB/s write, which the company says is five times speedier than the fastest 7,200 RPM hard drives, and twice that of SSDs shipping in 2008. On the reliability side, which is another concern when it comes to high usage Flash memory, SanDisk says its G3 series can withstand 160 terabytes written (TBW) for the 240GB version before the cells turn into read-only. By SanDisk's measurements, that translates to over a century of typical usage.
"SanDisk's G3 SSD has met the demand of a 120GB SSD at less than $250 with an exceptional user experience" said Rich Heye, senior VP and GM, Solid State Drives (SSD) business unit, SanDisk. "Three key features developed by SanDisk enable this new design: a new SSD algorithm called ExtremeFFSTM allows random write performance to potentially improve by as much as 100 times over conventional algorithms; reliable 43nm multi-level cell (MLC) all bit-line (ABL) NAND flash; and SanDisk's new SSD controller, which ties together the NAND and the algorithm."
SanDisk plans to start selling its G3 SSDs by the middle of 2009 in 60GB, 120GB, and 240GB capacities for $150, $250, and $500 respectively.
