Our review
Pros
  • Covers sequential, random, mixed, IOPS, bandwidth, and latency workloads
  • Runs on Linux, Windows, macOS, and several Unix-like systems
  • Exports normal, terse, JSON, and JSON+ result formats
  • Defines custom workloads with its Workload Model Language
  • Reports per-operation throughput, IOPS, latency, and histograms
  • Supports random, sequential, direct, and synchronous-write testing
Cons
  • Command-line and job-file workflows require technical familiarity
  • Results and workload behavior depend on configuration choices
  • Focused on engineering measurement rather than guided visual analysis
  • Command-line execution requires locally compiled and installed software
  • Workload modeling requires defining filesets, processes, threads, and flowops
  • Directory platform coverage is limited to Linux
Our verdict

fio is an open-source I/O tester for measuring storage and filesystem performance. It is intended for engineers and administrators who need configurable benchmarks across Linux, Windows, macOS, and several Unix-like operating systems.…
