SanDisk has developed a new file system called ExtremeFFS, which uses a page-based method that no longer ties the logical location of data on the drive to its physical space. The new file system dynamically writes and alters the position of data on the drive based on where it would be most efficient as well as the user’s own habits. The new file system improves the random write speed by 100x compared to current drives. It also improves reliability as it reduces the tendency to write in the same physical space on regular basis and thus reducing wear.
SanDisk has also proposed two new standards for solid state drives performance and reliability. The first standard Virtual RPM or vRPM would rate the performance of an SSD relative to the normal hard drives. The second standard, Long-Term Data Endurance, would measure the amount of writes available to an SSD and it will be a measure of real lifetime of the drive versus older concepts such as Mean Time Between Failure. Both the standards, if adopted would provide accurate data about performance and longevity of the SSD.
SanDisk plans to ship SSD based on ExtremeFFS file system in 2009. The company claims that those drives will be at least six times faster that present 2.5-inch notebook hard drive.
