OK.  That is interesting.  I am assuming tps is transfers per sec?

I would have to get a stop watch, but it seems to go a bit of time, and then a write.

Is there something that would accumulate this and give me a summary over some period of time?  Of course it better NOT be doing its own IOs...

    I just built a CentOS7 system on a Zotac NANO PC.

    I used a 320GB 2.5" HD I had sitting around and installed with
    Standard
    Partitions on XFS.

    The drive is spinning, nonstop.

    How can I monitor if there is actually disk i/o to warrant this
    constant
    spinning.

    So noatime for all partitions work with XFS?  I did some browsing and
    the claim is XFS uses realtime which is better? than noatime?

    Perhaps it is just occasional writes to messages (at least 1 a
    minute)
    that determines to keep on spinning.

    But it is annoying.
