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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
