Yes, sure, nothing is :-) Still I think anything is beter than FAT filesystem with synchronous writes (FAT table updated after writing each cluster) which is typical usage for memory cards. Ext2 or even ext3 witch asynchronous writes and noatime should be much better. Here are quite interesting links I found later http://www.gossamer-threads.com/lists/linux/kernel/984032#984032 http://www.linuxconf.eu/2007/papers/Engel.pdf http://www.linux-mtd.infradead.org/doc/ubifs.html#L_raw_vs_ftl
