"We build car infotainment systems. If the filesystem breaks, the system shuts down and the driver is left in the dark. We test to the extreme and found out that Datalight's Reliance Filesystem, never breaks! Very re-assuring in a competitive market. Well Done!"

Reliance Edge™

File System for Decision-Quality Data at the Edge of the IoT

Reliance Edge™ is the only file system designed to capture and preserve decision-quality data with deterministic behavior required by today’s autonomous systems. Reliance Edge is a transactional file system that protects critical system and user data from corruption specifically for systems where power loss may occur. Datalight’s unique file system works with a broad array of storage media including: eMMC , SD/MMC, NVRAM, USB mass storage, and SATA (or PATA) disks. Reliance Edge continues the legacy of file system products in the Reliance family that have shipped in hundreds of millions of devices.

Reliance Edge can be configured to meet the specific needs of your application by reducing complexity, optimizing resource use, and maximizing performance. Whether your application requires a single log file, a pre-defined set of files with fixed names, or complete flexibility to modify file hierarchy during runtime, Reliance Edge has easy to understand options. Data storage experts at Logic Technology can help you make the most of them. Our POSIX-like API option makes integration straightforward and Reliance Edge has the configuration flexibility to fit into even the tiniest of systems.

This video shows how the power failsafe file system Reliance Edge protects critical system and user data from corruption, while the FAT file system does not.
