    I believe that implementing RAID in the filesystem has many benefits too:
    - multiple RAID levels: store metadata in triple-mirror RAID 1, random
    write intensive data in RAID 1, bulk data in RAID 5/6
    - improved write throughput - since stripes can be variable size, any
    large enough write fills a whole stripe
