GitHub CodeQL vs simple-disk-benchmark

GitHub CodeQL has no write-up on Specifiction yet; its figures are above.

simple-disk-benchmark is a free command-line tool for measuring disk read and write performance on Linux, macOS, and Windows. It can run read tests, write tests, or both, with controls for test-file size, block size, cycle count, and random seeking. Results are shown in a bar chart and can be exported as JSON, including timing summaries and individual run timings. The benchmark creates a file of the selected size at the chosen path, deleting any existing file there. Options let users keep the file after a run, skip file creation, and choose whether the file is closed between cycles. The project describes cache-bypass methods for macOS and Linux. Install it with Cargo on all listed platforms or with Homebrew on macOS. The project says macOS and Linux are tested; Windows support is limited to unit tests, with no other testing or validation stated. It is MIT licensed, and the README suggests piping JSON output to jq or csvkit for CSV use.
