DiskSpeed

DiskSpeed provides a frontend for Microsoft's Diskspd, an application that can evaluate the storage performance of various types of servers. Its major advantage is that it enables the user to see the test results in a user-friendly window and export them in nice-looking reports.

Before using DiskSpeed, you should know that it requires the Diskspd executable file to be located in the same folder.

Secondly, note that DiskSpeed is, in fact, a Powershell script, so it will launch with Powershell in Windows. There is one problem here that you might face, which is related to the execution policy enstated on your computer. By default, Powershell has a restricted execution policy (you can view its status by running the "Get-ExecutionPolicy" command in Powershell). To change it, you must run the "Set-ExecutionPolicy - ExecutionPolicy Unrestricted" command, provided that Powershell is launched with administrative rights (otherwise, none of these commands work).

To run the DiskSpeed script, you must also launch Powershell as an admin. If everything is fine, you should be finally able to see the main window of DiskSpeed.

There are various predefined tests in DiskSpeed. The application runs tests against database and email servers, archical file servers, and streaming media servers. You are free to customize the size of the test file (1GB by default), the size of the transferred data block, the access type (random or sequential), and the duration of the test.

The results are displayed in the main window of DiskSpeed and can be exported as an HTML or CSV report that is easy to read and share.
