The company's new Flash File System (FFS... yes we know... stop sniggering back there) will ship with devices in early 2009.
Extreme FFS operates on a page-based algorithm, which, according to Sandisk's boffins, means there is no fixed coupling between the physical and logical location of data. When a sector of data is written, the SSD puts it where it is most convenient and efficient. The result is an improvement in random write performance – theoretically by up to 100 times – as well as in overall endurance.
The system also learns user patterns and, over time, will know where to park frequently-used chunks of data.
