N2 - Car digital video recorders store real-time audio/video data at flash memory storage devices. They require high performance and high reliable file systems. However, current file systems are vulnerable to sudden-power-off and flash memory errors. This paper proposes flash-aware cluster allocation techniques that can reduce the probability of file system corruptions and file fragmentation. Experiments on a real system showed that the proposed techniques can prevent the file fragmentation and can improve the write performance and SD card lifetime significantly.
