To add a bit of slightly more advanced discussion, the main reason for larger strips ("chunk size) is to avoid the huge latencies of disk rotation using unsynchronized disk drives, as detailed here: http://www.sabi.co.uk/blog/12-thr.html?120310#120310 That relates weakly to Btrfs. -- 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
