    WRT sensitivity is note #3 here inaccurate?
    https://www.illumos.org/issues/2665#note-3

    As an example, here is a device that is particularly problematic...
    The HDS721010DLE630 which reports itself to the OS as vid = "ATA "  and pid
    = "Hitachi HDS72101" which should be handled by the following in sd.conf

    sd-config-list =
        "ATA     HITACHI HDS72101", "physical-block-size:4096";

    However, it isn't. Nor is it caught by any amount of wildcarding around all
    or portions of those ID strings. Pools create stubbornly at ashift 9.

    Any advice?
