and checksums (bit rot prevention)

  I'm amazed at how generally unreliable drives are at retrieving stored data with ZFS checksums in place to highlight the problem - it seems that on average every TB of storages has a problem with a block every half-year or so.

    And every 4GB of memory or so if you have ECC turned on.
