With the growth in size of flash, just how long do you think it will continue to be used before you go to something larger? A 256MB flash of a few years ago has been supplanted in many cases by today's 2-4gb memory. One suggestion with ext2 might be to mount it with the noatime option, so it doesn't update the last access time for directories and files. Otherwise, you are doing a write even when you only plan to read a file.
All of the posts fail to address the question here: what is the correct file system, or does one exist yet, for wear leveling flash storage. JFFS2 and logfs are nice for MTD, but for better flash memories that are likely to be used in the future like solid state hard disks, what is the answer? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
