What is Diskspd?

Diskspd is a storage testing tool created by Microsoft Windows, Windows Server and Cloud Server Infrastructure Engineering teams. It combines robust and granular IO workload definition with flexible runtime and output options. That makes it a perfect tool for storage performance testing, validation and benchmarking.

Where to find Diskspd?

Diskspd is a free and open source utility. Its source code can be found on GitHub. The repository also hosts other frameworks which use Diskspd. You can find them under ‘Frameworks’ directory. A binary release is hosted by Microsoft at the following location: http://aka.ms/diskspd.
