About This File

We, at computingondemand.com, had been looking for a way to benchmark a NAS in a repeatable form without the need to buy additional software.  For us, we had been performing a test in our NAS reviews that benchmarks the speed at which you can transfer a 2gb file to and from a NAS. 

INSTRUCTIONS FOR USE:  First, extract the zip (located below) file to c:\2gbtest.  After that, all you have to do is execute the StartTest shortcut in the c:\2gbtest folder by right clicking it and choosing “Run as Administrator“.  Please note that this batch file uses the command for robocopy and fsutil.  Windows 7 should have these by default.  If you are running Windows XP and do not have robocopy, you need to download the Windows Server 2003 Resource Kit (directly from Microsoft).

The batch file requires admin authentication to use the fsutil command.  This command creates the file at 2GB.  You will be prompted by Windows to allow this application to execute with these privileges. The script will try to find files that may already exist within the C:\2gbtest folder and remove them.

Once you are ready to proceed, just press any button on your keyboard. The benchmark will then create a file that is exactly 2GB in size

Next, the application will ask you 3 very specific and important questions:

  1. The hostname or IP of your NAS (example answer would be : SERVER)
  2. The Shared folder on the NAS to run the test from (example answer would be: documents)
  3. How many times you want the test to loop (example answer would be: 10)

This will create a path for robocopy of \\SERVER\Documents\2gbtest\

The application will then run through the test, looping for as many times as requested.  Once completed, it will create a .CSV file with the results in MB/m form as reported by robocopy.  At the bottom of this document, it will calculate the average result for each test in “To NAS” and “From NAS” and then divide it by the number 60 (for seconds in a minute) to calculate the results in the form of MB/s.

Just to note, the above results were generated using a file size or 50,050 bytes for the purposes of this tutorial.

Thinking about it, if documented properly, you can use these results to benchmark LAN and WIFI speeds on your network or to calculate your network adapter’s performance.
