## What it is
KDiskMark is an open-source HDD and SSD benchmark tool for Linux with a friendly Qt-based GUI, acting as a frontend to the Flexible I/O Tester (fio). It provides configurable test presets, report generation, and a CrystalDiskMark-like result view.

## Use cases
- benchmark my ssd on linux
- test hard drive read write speed
- crystaldiskmark alternative for linux
- measure disk iops and latency
- compare storage performance before and after upgrade
- generate a disk benchmark report

## When to choose
- you need a GUI disk benchmark on Linux similar to CrystalDiskMark
- you want configurable block size, queue depth, and thread counts for storage tests
- you need shareable benchmark reports

## When to avoid
- you need disk benchmarking on Windows or macOS
- you want scripted headless benchmarking without fio directly
- you need filesystem-level or real-world workload benchmarks rather than synthetic fio tests

## Facets
- artifact type: application
- maturity: active
- function: benchmarking, gui
- domain: developer-tools, performance
- platform: cpp
- tags: disk-benchmark, ssd, hdd, qt5, fio, crystaldiskmark-clone, storage, command-line, linux
