How to Test HD Speed?

This is a continuation from my prior post. I just didn't get enough information to figure out a good way to test the HD speed within my G5 tower. I have 2 internal HD's, but one is the boot device. That boot drive seems to take almost twice as long as the stock Apple 80 gig Maxtor HD to duplicate a folder.

My question is whether this is a good way to test the speed of the HD? If not, what is a better way of doing this? I just want to be sure that my computer is running as efficiently as possible...

I think Drive Genius has an option to benchtest drives...

I have no less than 5 utilities that can test drive speed. Too bad they are all for OS 8 and 9.

The most accurate representation of Drive speed will come from a test that forces reading and writing from the drive simultaneously.

Create a folder 1000MB in size, use a photoshop file or some MP3's, copy the folder to both drives, and then get out your stopwatch.

For the sake of accuracy you should reboot the computer and make sure that no processes are running in the background.

Ready the stopwatch and then click on your 1000MB file hit command + D and start the stopwatch at the same time, this will tell the Mac to duplicate the folder and cause the drive to read from and write to itself simultaneously!

Stop the watch when the duplication ends and record the time in seconds. Restart the computer and do this again two more times on the same drive, so that you can get an accurate average, before switching to the second drive and repeat.

Fastest average time wins!!

Of course the clooser to identical the drives are from a software standpoint the better, ie if you can clone one drive to the other so that the contents are identical.
