Summary
simple-disk-benchmark is a command-line utility for measuring disk read and write performance on Linux, macOS, and Windows. Run read tests, write tests, or combine both, then view run times in a bar chart or export summaries and individual timings as JSON. Test settings include file size, block size, number of cycles, and random seeking. The benchmark creates a file at the chosen path; if a file already exists there, it will be deleted. Options let you retain the test file, skip creating it, and choose whether it closes between cycles. The project describes cache-bypass methods for macOS and Linux. Install through Cargo on all supported platforms or Homebrew on macOS. macOS and Linux are tested, while Windows validation is limited to unit tests. The software is MIT licensed and free. Its README suggests using jq or csvkit with JSON output for CSV workflows.
Who it is for
It suits people who want command-line disk read or write benchmarks with configurable test parameters and exportable timing data. Windows users should note that support has limited validation.
What is good
- Runs read tests, write tests, or both.
- Controls include file size, block size, and cycles.
- Shows timings in a bar chart.
- Exports summaries and individual timings as JSON.
- Free and MIT licensed.
What to know first
- Windows validation is limited to unit tests.
- An existing file at the chosen path is deleted.
- Multithreaded benchmarking is listed as a TODO.
Verdict
simple-disk-benchmark offers configurable disk tests and timing exports in a free command-line tool. Check the selected file path before running it, and keep the limited Windows validation in mind.
