disk-mark-me review
A focused Unix disk benchmarker with CrystalDiskMark-like profiles and IOPS reporting.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
disk-mark-me is an open-source command-line shell script for benchmarking storage devices with fio. It targets Linux systems, including embedded gaming devices, and provides beta support for macOS. The tool is suited to users who want CrystalDiskMark-like sequential and random read/write tests from a Unix command line, with results presented in a familiar format.
Its testing controls are broader than a fixed preset runner. Users can choose a target directory, test-file size, benchmark rounds, and read/write selection. The script reports throughput in MB/s and input/output operations per second, while verbose per-round output gives more detail about each run. Prerequisite and disk-space checks add practical safeguards, and disk-cache clearing is available before read tests when permitted. These controls make disk-mark-me a useful fit for repeatable storage comparisons and targeted checks across different directories or devices.
The main trade-off is scope. disk-mark-me focuses on throughput and IOPS rather than presenting a verified latency view, so it is less suitable for buyers whose primary requirement is latency analysis. Its shell-script and command-line design also favors technically comfortable users over people seeking a graphical workflow. Choose it for free, open-source sequential and random storage benchmarks on Linux, or for evaluating the beta macOS support. Choose an alternative when a graphical interface, mature macOS support, or latency reporting is central to the decision.
