DiskSpd is a free and open-source [2] command-line tool for storage benchmarking on Microsoft Windows that generates a variety of requests against computer files, partitions or storage devices and presents collected statistics as text in the command-line interface or as an XML file. [3] [4] [1]

Overview

The command supports physical and virtual storage including hard disk drive (HDD), solid-state drives (SSD), and solid-state hybrid drives (SSHD). [5] It provides control over the testing methods, duration, threads, queues, IO and processor affinity, and reporting. [6]

In 2024, the command was updated to handle modern workloads and hardware like NVMe. [7]

DiskSpd works on desktop versions of Windows 7, Windows 8, Windows 8.1, Windows 10, as well as Windows Server 2012, Windows 2012 R2, and Windows Server 2016. [8]

It is licensed under MIT License and the source code is available on GitHub. [9]

Example

Benchmark two drives (C: and E:) using a 100 MB test file, and run the test for a duration of 60 seconds (the default is 10). [10]
