Failsafe Flash Filesystem (F3S)
SKU: WCE-F3S |
Description
Single Board Computers with Windows CE generally use the file system FAT32. This file system operates with allocation tables (FAT). If an electrical power outage occurs during a writing cycle, the FAT and also the file itself can be damaged (inconsistent state). As a last resort it is necessary to reformat the storage. With the file system TFAT from Microsoft you can avoid damaging the allocation table but not the data within a file itself.
F&S has developed the Failsafe Flash File System (F3S), which is designed especially for NAND-Flash-Memories. In contrary to other file systems, it is able to guarantee a reliability in transaction on file-level. The user has the option to define the point of validation of modified data. In easiest case by closing the file-handle.On this way, important data can be stored permanently and safely.
- Modifying file contents can only be accepted in completed operations (state-transistion).
- During modification, transistions can also be accomplished by using explicit calls within the application.
Because of the unique, transaction-based concept, it is fundamentally robust against unexpected electrical power outages.
In this way, important data can be stored permanently and safely.
