Test Disk IO performance


To execute this process I will use Iometer tool. You read more about here, http://www.iometer.org and download here http://www.iometer.org/doc/downloads.html

To configure the application I’ve made some options, check this images.

I’ve choose 20 minutes test, all the tests, and the drive to test.

In this process a command prompt will start and at the end you will have this output there.

You can read and analysis the result, and of course take your conclusions here.

This is a good tool when you pretend to test multiple disks.

Hope that this information can be useful.

  1. Should i just state just how pleasant it’s to find another person whom genuinely knows what they’re going over over the internet. You undeniably recognize how to debate an issue. With thanks!
