KDiskMark is a storage benchmarking tool for Linux that uses fio as its benchmarking engine while presenting results through a much friendlier interface.
It is particularly useful for quickly measuring SSD, NVMe and hard disk performance without constructing fio job files manually. Presets cover common storage tests, while individual workload parameters remain configurable.
KDiskMark was originally focused on its Qt graphical interface, but it now also offers an interactive terminal interface suitable for systems without a graphical desktop.
This is free and open source software.
Key Features
- Benchmarks storage devices using fio.
- Offers both a graphical interface and an interactive terminal interface.
- Runs sequential and random read/write tests.
- Provides configurable block sizes, queue depths and thread counts.
- Lets users select benchmark file size and number of loops.
- Supports configurable read/write mix ratios.
- Provides reusable benchmark profiles and presets.
- Can flush the page cache between tests.
- Supports direct I/O and options for controlling test-data behaviour.
- Detects copy-on-write filesystems when configuring suitable workloads.
- Supports different result units for easier comparison.
- Saves benchmark results as reports.

Hi Steve,
It looks like some wires got crossed somewhere.
The website link on this page point to Phoronix instead of KDiskMark.
Thanks, link fixed
