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
KDiskMark
A graphical disk benchmark for Linux that runs fio tests and shows easy-to-read results.
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.
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.
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.
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.

Related functionality, not a direct replacement.
GSmartControl
A graphical interface for smartctl that shows the health of hard drives and SSDs.
smartmontools
Reads the SMART health data built into disks and runs self-tests, giving advance warning before a drive fails.
f3
A command-line tool that tests flash drives and memory cards for fake capacity and real performance.
nvme-cli
A Linux command-line tool for managing, inspecting and formatting NVMe solid-state drives.
HDDScan
A free Windows utility for testing hard drives and SSDs, reading SMART data and running surface tests.
