How to test hard drive speed?

[luffy]

I just install a second hard drive this. The website said Rotational Speed : 7200 rpm. and Data Transfer Rates : 300 MB/s.
When I check the sticker on the hard drive. It said Data Transfer Rates : 150MB/s. And Nowhere mention about Rotational Speed.
Can you some recommend a free software to check this information?
Thank you.

Here are a couple to check the data rate, but not RPM:

Download Disk Bench 2.5.3.2 - Tests your hard drive speed in a real life situation - Softpedia
Roadkil`s Disk Speed Freeware download and review - test hard drive speed from SnapFiles

My disk test result is below Average. Is it a bad news? The hard drive is new. I just reformat it.

That does not have to be bad. It depends from model you bought. You have WD Caviar Blue (Performance and reliability -average performance ), WD Caviar Green (Cool, quiet, eco-friendly - low performance) ,WD Caviar Black (Maximum performance - max performance). Check which one is your model, and you'll know if you need to be worried.

if you need more performance then go for SSDs... they perform's very much faster than traditional magnetic disks...

Here is what you can expect from an SSD. Note especially the Access Time.

Well, SSD is great, but the price is really to much now. I just hope it will drop soon, so I can get myself one.

Thank you everyone.
I have been playing L4D, crysis, mirror's edge, mass effect on this hard drive. And it runs fine. Probably I'm worry to much.

This is exactly what I needed! Recently I tested it and it's the best piece of software!
