Software Acceleration for eMMC and Other Managed Flash
FlashFXe™ is the only storage acceleration software for eMMC that dramatically improves random write performance—closing the “performance gap” —while improving endurance and reducing power consumption of your embedded device. Designed to be used with the Datalight Reliance Nitro file system, FlashFXe has been developed by the experts that created the FlashFX® family of flash memory management tools--the top choice for data-critical applications from leading OEMs for decades. Datalight’s responsive and accessible support engineering staff will help streamline your development and get your project done quickly and efficiently.
System responsiveness is a top requirement for all embedded devices. Most flash media marketing highlights best case sequential performance and shows impressive throughput. Random I/O metrics can be much different. And in the real world, all I/O is random I/O. FlashFXe + Reliance Nitro closes the performance gap by bringing random write performance up to sequential speeds.
The lifespan of flash is becoming dramatically shorter, dropping from over 100,000 cycles to under 5,000 in just a few years. While acceptable for many semi-disposable consumer applications, industrial and long-lived embedded applications need strategies to extend flash life if they are to take advantage of the cost and performance benefits of newer parts. The efficiency of Datalight software allows far less data to be written compared to the basic Linux solution.
Reduced power consumption means extended working time for battery-powered devices, a key differentiator. Datalight software reduces the workload significantly which not only minimizes power consumption at the flash subsystem level to 1/6th of basic software configuration but frees the system to allow power-hungry peripherals to sleep more often.

How FlashFXe Works
FlashFXe provides performance and endurance benefits for OEMs building embedded systems using e-MMC for ease of integration and supply chain resilience.
With flash-aware allocation, intelligent synchronization and host RAM caching, FlashFXe balances the write patterns of the application with the write patterns most suited to eMMC flash to enhance performance and minimize write amplification. Critical data integrity and reliability our customers expect from Reliance Nitro is uncompromised.. Intelligent synchronization combines Datalight software's reliability benefits with performance, offering users the flexibility to synchronize data to the media as and when necessary, all the time maintaining the critical data ordering.
FlashFXe is especially suitable for multi-function mobile or portable devices with installable applications that rely on databases and offers power-saving benefits for battery powered devices.
