LAB 6-5 TEST HARD DRIVE PERFORMANCE USING SANDRA

 

Objectives

The goal of this lab is to help you use SANDRA to compare the performance of your system’s drives against similar drives. After completing this lab, you will be able to:

➤ Use SANDRA to test your drive’s performance

➤ Use SANDRA to compare your system’s drives with similar drives

 

Materials Required

This lab will require the following:

➤ Windows 9x operating system

➤ SiSoft SANDRA 2008

 

Download and Install SANDRA

  1. Go to www.teechur.com and download SANDRA (on this module’s homepage). Or get it in the PUB folder

SANDRA Lite can be used to run all sorts of tests on your hard drive. It should give you a nice indication of how your drive is running. We’re going to use SANDRA to test our hard drives. SANDRA is actually updated quite often, so if you use it at a tech you’d want to check for the newest version.
