Alternatives to KDiskMark

A graphical disk benchmark for Linux that runs fio tests and shows easy-to-read results. The listings below can replace it for an important use case. Each note says what changes if you switch.

The original

Replacements

Listings that take over the same core job as KDiskMark.

  • fio

    A flexible command-line I/O tester for benchmarking and stress-testing storage devices.

    fio is the command-line engine behind KDiskMark, offering far more configurable job files and detailed latency reports without a graphical interface.

  • CrystalDiskMark

    The standard Windows disk benchmark, measuring sequential and random read and write speeds in a few clicks.

    CrystalDiskMark is the Windows benchmark KDiskMark imitates, with peak and real-world modes, and does not run on Linux.

  • GNOME Disks

    A graphical disk utility for GNOME that partitions, formats, benchmarks and images drives on Linux.

    GNOME Disks includes a basic read and access-time benchmark within a broader Linux disk utility, with fewer test options.

  • DiskSpd

    Microsoft's command-line storage load generator for benchmarking disk performance on Windows.

    DiskSpd is Microsoft's configurable command-line load generator for Windows, aimed at administrators rather than quick checks.

  • ATTO Disk Benchmark

    A free benchmark from ATTO Technology for measuring storage read and write performance.

    FreeProprietaryWindows

    ATTO Disk Benchmark is a free proprietary Windows tool for quick read and write speed tests.

  • AS SSD Benchmark

    Quick Windows benchmark tool for testing SSD read and write speeds.

    FreeProprietaryWindows

    AS SSD Benchmark is a free closed-source Windows benchmark focused on SSDs, needing no installation.

Also worth comparing

These listings name KDiskMark as their own alternative, so the relationship runs both ways.

  • HD Tune

    Benchmarks storage drives and scans them for errors and S.M.A.R.T. warnings.

    FreemiumProprietaryWindows

    KDiskMark is a free Linux disk benchmark built on fio with configurable block size and queues, but it does not scan for errors or read S.M.A.R.T. data.
