disk-mark-me

Spec sheet

Purpose

disk-mark-me is a shell script that benchmarks disk performance using fio and formats results similarly to CrystalDiskMark’s default profile.Read 5 Oct 2026 · github.com

License

The repository states that the script is released under the MIT License.Read 5 Oct 2026 · github.com

Benchmark profile

The default profile uses sequential 1 MiB tests at queue depths 8 and 1, and random 4 KiB tests at queue depths 32 and 1, each with one thread.Read 5 Oct 2026 · github.com

Cache clearing

It attempts to clear disk caches before read tests using operating-system-specific methods when permissions allow; sudo is optional and recommended for this.Read 5 Oct 2026 · github.com

Comparability

The maker advises using results to compare performance within the same operating-system environment because results across operating systems should not be directly compared.Read 5 Oct 2026 · github.com

Compatibility limit

The README advises against directly comparing results across operating systems because storage stacks, hardware interfaces, fio engines, and filesystems can affect results.Read 5 Oct 2026 · github.com

Customization

Options include the target directory, test file size, number of rounds, benchmark type (read, write, or both), and verbose output.Read 5 Oct 2026 · github.com

Installation

The maker recommends installing with the provided Makefile, either to ~/.local/bin or to a system-wide location such as /usr/local/bin.Read 5 Oct 2026 · github.com
