And your last sentence is precisely why I raised my point in the first
place.

The abstract from the report reads:

     [..] we conclude that models based on SMART parameters alone are
    unlikely to be useful for predicting individual drive failures.


And that is my point, "individual drive failures", that is, those on a
single machine, which is what we were discussing if I'm not mistaken.

Now if you want to add SMART statistics to the landscape-sysinfo tool
that Gustavo is working on, that's a whole different thing.
