How to Test Hard Drive Speed

description
Info Level: Beginner Presenter: Eli the Computer Guy Date Created: July 12, 2013 Length of Class: 19:26 Research Assistance: Tracks Computer Repair Prerequisites None Purpose of Class This class teaches students how to test the speed of their hard drive Class Notes Hard Drives are usually the bottleneck on PC's and Servers, but most technicians do not consider upgrading them in relation to speed. Even brand new computers can come with relatively slow hard drives. Sequential Read/ Write speed means the speed in relation to single files Random Read/ Write Speed means the speed in relation to numerous files IOPS is the amount of Input/ Output Operations per Second. This means the individual transactions that the hard drive can handle. This is generally important for the preformance of databases. Parkdale speed test is an easy to use/ easy to understand test, but there are numerous other ones to choose from. Corrections Lab Setup Used in Demonstration The ETCG Host Computer Specs are: ASUS Model: CM6870US01 16 GB of RAM 120 GB Intel 330 Series SSD Hard Drive 1 TB 7200 RPM Hard Drive i7 3.4 GHz Intel Processor Study Guide Resources http://thesz.diecru.eu/content/parkdale.php
