Use the option below to combine reads and writes in the latency output:
unified_rw_reporting=bool
Fio normally reports statistics on a per
data direction basis, meaning that read, write, and trim are
accounted and reported separately. If this option is set,
the fio will sum the results and report them as "mixed"
instead.
