YAFFS
YAFFS was the first log-structured filesystem designed specifically for NAND flash. It is fast, simple and portable with a very low RAM footprint. It can be used standalone or in RTOSs as well as in Linux via the MTD. YAFFS2 is stable and has widespread use. It has recently gained checkpointing so that boot-up scan is avoided, saving huge amounts of time on large flash partitions. This talk will cover the filesystem structure and design choices, OS integration options and future development directions as NAND flash hardware develops.
