KDiskMark is an HDD and SSD benchmark tool with a very friendly graphical user interface. KDiskMark with its presets and powerful GUI calls Flexible I/O Tester and handles the output to provide an easy to view and interpret comprehensive benchmark result. The application is written in C++ with Qt and doesn't have any KDE dependencies.

• Configurable block size, queues, and threads count for each test
• Many languages support
• Report generation

sudo snap install kdiskmark
sudo snap connect kdiskmark:removable-media # external storages

KDiskMark is included in the official extra repo. You can install it like any other package:

sudo pacman -Syu kdiskmark

Development version can be installed from AUR kdiskmark-git package.

git clone https://aur.archlinux.org/kdiskmark-git.git
cd kdiskmark-git
makepkg -si

KDiskMark is included in the official Fedora repo. You can install it like any other package:

sudo dnf install kdiskmark

sudo zypper install kdiskmark

You can build KDiskMark by using the following commands:

mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=Release ..
cpack -G DEB # Or RPM, ZIP etc.

To build KDiskMark with Qt6 instead of the default Qt5, use the USE_QT6 flag during the CMake configuration step:

mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=Release -D USE_QT6=ON ..
cpack -G DEB # Or RPM, ZIP etc.

To help with localization you can use Crowdin or translate files in data/translations with Qt Linguist directly. To add a new language, copy data/translations/kdiskmark.ts to data/translations/kdiskmark_<ISO 639-1 language code>_<ISO 3166-1 alpha-2 language code>.ts, translate it, then add the file to the TS_FILES variable in CMakeLists.txt, and create a pull request. It is also possible to add localized Comment and Keywords sections into data/kdiskmark.desktop and message for PolicyKit authorization into data/dev.jonmagon.kdiskmark.helper.policy.
