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]
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]
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]
