Overview

fio-iops-probe is a lightweight shell script that runs FIO (Flexible I/O Tester) to measure storage IOPS. It tests combinations of block sizes (4k to 128k) and I/O modes (randread, randwrite, read, write), saves results as JSON (if jq is available) and text reports, then optionally cleans up the test file.
