Fail Safe Embedded File Systems
Using SD card storage media in embedded systems presents risks that may lead to serious loss of valuable data or, worse, corruption of the file system with no hope of recovery. In embedded applications this is an unacceptable scenario but, with careful design, it is a situation that never need occur. Using a fail-safe file system is one way to alleviate this problem but no file system can reduce the risk to zero on its own - it must be part of a system level approach to reliability. At the most fundamental level, for any system to be considered truly fail-safe, all layers of the system must be predictable and specify required behavior. Using an HCC fail-safe file system in conjunction with Swissbit’s specially designed range of industrial SD cards with integrated power management provides a guarantee of reliability.
