Description Martin Birgmeier 2016-03-29 06:36:00 UTC
- Writing data to a SEAGATE ST32155N
- Controller is Adaptec AHA-2940AU
- Running "gstat -f da0"

- gstat shows the following output:

 L(q)  ops/s    r/s   kBps   ms/r    w/s   kBps   ms/w   %busy Name
  285     57      0      0    0.0     57   3641   2017   99.6| da0

Expected result:
- The product of w/s and ms/w should be less than 1000.
- Or the manual page should explain what the numbers mean.
