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

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.

• BUILD_WITH_PAGECACHE_CLEARING_SUPPORT enables pagecache clearing functionality (default is ON). If disabled, the application will not be able to clear the pagecache in any way.
• PERFORM_PAGECACHE_CLEARING_USING_KF5AUTH determines whether a helper will be built (default is ON). If the KF5Auth helper is not built, the application will be able to clear the pagecache if it is run as root.

Build parameters are passed at configuration stage:
cmake -D PERFORM_PAGECACHE_CLEARING_USING_KF5AUTH=OFF ..

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.
