SanDisk pitches 100x SSD speed boost tech

From Register Hardware:

SanDisk has come up with a tweak for solid-state drives that, it claims, will accelerate SSD random write speeds by a factor of 100.

Dubbed ExtremeFFS, the technology is a Flash file management system that decouples physical and logical storage, allowing data to be written to a drive randomly yet very quickly. Essentially, individual writes are cached in virtual storage - Ram, presumably - then written en masse, a sector at a time, to the optimum location in the Flash bank, chosen by the wear-leveling algorithm.

This hides the actual to-Flash write from the write operation instigated by the OS, in turn, creates the illusion of that apparent 100x increase in random write speed. Writing a sequence of data to an SSD is much faster than writing it randomly, bit by bit.
