The File Allocation Table (FAT) file system is commonly used in embedded storage devices such as Multimedia Cards (MMC) / Secure Digital (SD) / Micro SD cards, NOR, NAND flash memories. The Extend File Allocation Table (ExFAT) is the future file system for embedded storage devices. The MMC and SD card associations classify the ExFAT as the standard file system for storage flash cards of more than 32 Giga Bytes (GB) of size. This paper discourses the techniques to adapt the file read optimizations, Reduction of File Allocation Tables techniques and Cluster Heap for file write optimizations of ExFAT file system to FAT file system to improve the file read and write performance and the endurance of flash device
