A respected and commonly used utility for measuring hard drive performance is HD Tach. The "non-commercial" version is a free download. To get best results, deactivate GoBack before running any tests.
On this page I have the measurement results for these different computer configurations. You can click the link to go directly to the section on this page.
A list of hard drives is presented. Click on the entry for the drive you have, which for me is the Western Digital Caviar SE 1200JB. Then click the "Select" button.
This brings up the first graph again, but now with the comparison hard drive also shown in blue. Now it's much easier to know what to think of the results. The results show my results (graphed and titled in red) are within expectations, and are actually a little better than the comparison hard drive (results graphed and titled in blue) in "Sequential Read Speed", "Random access" time and "Average read" time.
The results look about the same if you go back to the main screen and run the other test by selecting the "Long bench (32mb zones)" option.
Here is the comparison graph. The results show that my results are better than the comparison hard drive in "Sequential Read Speed". Notice the "Random access" time is lower (lower is better), and the "Average read" is much larger (higher is better).
And again the results look about the same if you go back to the main screen and run the other test by selecting the "Long bench (32mb zones)" option.
This time the hard drive is the Wester Digital Caviar SE 2500JD.
And again it appears my results are within expectations and are even a little better than the comparison configuration.
The results don't change much using the "Long bench (32mb zones)" option.
Hard Drive Performance Speed Tests
The performance results you get may vary due to factors such as the speed of the Front Side Bus (FSB) and the ATA supported by the computer. Don't forget to reactivate GoBack when you're ready.
