I think you'll get more out of btrfs, but another thing you can look into is ext4 without the journal. Support was added for that recently (thanks to google). -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
