San Jose, CA (Embedded Systems Conference), – March 30, 2009 – Datalight announced Reliance Nitro, a new tree-based file system with broad performance implications for embedded device manufacturers around the globe.  Early tests show sequential and random write speeds as much as five times faster on Microsoft Windows Mobile than the default file system, allowing devices like smartphones and digital cameras to store and access large amounts of data without the lag time often experienced when dealing with multimedia and other large files.

To make Reliance Nitro faster than other file systems, the Datalight engineering team analyzed all I/O operations, eliminated all redundant calls to the disk, and optimized the file system’s disk operations. This translates into much faster throughput speed for read and write operations. In fact, the revolutionary tree-based allocation structure allows Nitro to be up to 100 times faster on file operation speeds, enabling a much more responsive user experience.

The new file system will initially be available for Windows Embedded CE, Windows Mobile, and Wind River VxWorks. An RTOS porting kit will be offered to allow porting to any 32-bit operating system. Like Reliance, the well-known transactional file system on which it is based, Reliance Nitro provides 100% data reliability and fast mount times.

“Our intent in building Reliance Nitro was to mitigate the sluggish performance associated with increasing data storage on devices,” said Roy Sherrill, Datalight CEO. “Nitro will allow users to finally enjoy the high speed capabilities of flash. We expect fast adoption as manufacturers vie for the loyalty of customers seeking better performing devices.”

Reliance Nitro is available immediately from Datalight and the Datalight worldwide network of channel partners. Please visit us at to find a reseller near you.
