Facts

Purpose
disk-mark-me is a shell script that benchmarks disk performance using fio and formats results similarly to CrystalDiskMark’s default profile.github.com · 5 Oct 2026
Read/write tests
It tests sequential and random read and write performance.github.com · 5 Oct 2026
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.github.com · 5 Oct 2026
Results
Results are displayed in MB/s and IOPS, and measurements are averaged across the configured rounds.github.com · 5 Oct 2026
Customization
Options include the target directory, test file size, number of rounds, benchmark type (read, write, or both), and verbose output.github.com · 5 Oct 2026
Prerequisites
The script requires fio, numfmt, and standard command-line utilities including grep with PCRE/-P support, awk, bc, df, stat, id, touch, and rm.github.com · 5 Oct 2026
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.github.com · 5 Oct 2026
Installation
The maker recommends installing with the provided Makefile, either to ~/.local/bin or to a system-wide location such as /usr/local/bin.github.com · 5 Oct 2026
Linux support
The maker describes support for Linux distributions including Debian/Ubuntu and embedded handheld systems running JELOS or ROCKNIX.github.com · 5 Oct 2026
macOS support
macOS support is marked beta, and the instructions call for fio and GNU coreutils installed through Homebrew.github.com · 5 Oct 2026
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.github.com · 5 Oct 2026
Usage considerations
The maker notes that benchmarks may take significant time, frequent intensive writes can wear SD cards, and other I/O activity can skew results.github.com · 5 Oct 2026
Support and contributions
The maker invites users to open an issue or submit a pull request for improvements or bug fixes.github.com · 5 Oct 2026
License
The repository states that the script is released under the MIT License.github.com · 5 Oct 2026
Tests
It tests sequential and random read and write performance and reports results in MB/s and IOPS.github.com · 5 Oct 2026
Supported systems
The project describes support for Linux and beta support for macOS, including Linux handheld gaming consoles running JELOS or ROCKNIX.github.com · 5 Oct 2026
Requirements
It requires fio, numfmt, and standard command-line utilities including grep with PCRE support, awk, bc, df, stat, id, touch, and rm.github.com · 5 Oct 2026
Compatibility limit
The README advises against directly comparing results across operating systems because storage stacks, hardware interfaces, fio engines, and filesystems can affect results.github.com · 5 Oct 2026
macOS limit
The project labels macOS support beta and says GNU coreutils and, when needed, GNU grep should be installed and available in PATH.github.com · 5 Oct 2026
Usage cautions
The README says intensive write benchmarks can contribute to SD card wear and that other I/O-intensive processes can skew results.github.com · 5 Oct 2026
