FIO is very flexible io generator, i would call it IO swiss knife. Currently we have tonnes of hardcoded application which reproduces some predefined scenario. This approach has obvious dissadvantages 1) Lack of flexability: once written it is hard to modify it in future 2) Code base is large, many routines written again and again At the same time add new fio based tast is just add simle INI file. This greatly simplify code review. I do beleve that some day we will replace most of hardcoded io binaries with fio.
