Diskspd

2.2 Storage benchmarking utility for Windows

Measure performance of drives, networks and SANs for optimal configuration.

Diskspd is a free and open source workload simulator app and HDD tool, developed by Microsoft for Windows. It's pretty advanced.

The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of Diskspd to illustrate the user interface and show the overall usage and features of this workload simulation program.

Test the speed and performance of connected storage devices

DiskSpd is a storage performance tool from the Windows, Windows Server and Cloud Server Infrastructure engineering teams at Microsoft.

It was designed to be used in a variety of scenarios including performance testing, capacity planning and storage subsystem characterization.

DiskSpd is a command-line tool that allows users to specify a variety of options and parameters to control the test. You can do this with their the cmd.exe or from within Windows PowerShell.
