The new SSDs are about twice as fast as a typical netbook hard disk drive

SanDisk Corp. today announced the general availability of two new solid state disk (SSD) drives for netbooks that it said increase random read/write rates by as much as nine times over its first generation netbook SSDs.

SanDisk's unveiled the new drives at Computex, in Taipei. The SSDs use a common method to store writes in cache memory, waiting until the SSD is in an idle state to then lay them down. The method normally uses DRAM cache memory. SanDisk, however, said their new pSSD P2 and pSSD S2 drives use a new technology called nCache, which instead of DRAM, uses nonvolatile NAND flash memory as a cache to store writes more efficiently before laying them down on the drive.
