I think fio will report something similar back on Linux when it is able to work it out - see the "And finally, the disk statistics are printed" section over in https://fio.readthedocs.io/en/latest/fio_doc.html#interpreting-the-output . The util percentage might be as good as it gets (i.e. a device that can take more I/Os will have a low percentage). I think iostat produces similar output to that too... -- Sitsofe | http://sucs.org/~sits/
