2011 Macbook Pro Hard Drive noise.

Hi all.
Just bought a new Macbook Pro and started to make some Hard Drive noise. Like is working (write/read data).
Especially if you open some softwares, like CS5, Nero,...

I have a old 2009 Macbook Pro and never have this kind of sound (or is not so strong). Is very quiet.
My wife have a 13' Macbook Pro and the noise/sound is very low. But with the new 2011 is more prominent.

This is normal? Something to do with the new processors?

Anyone have the same experience?

Thanks

Mac OS X (10.6.6)

I have a mid 2012 15 inch and it too is loud. It also made the clicking noises. I fixed it by removing a small part as shown here http://tenonedesign.com/blog/fix-your-macbook-pro-like-a-champ/

"The bottom cover of the MacBook Pro serves as a shield for radiated electromagnetic energy. A great shielding strategy is to find a huge piece of metal, and connect your circuit to that metal wherever possible. The MacBook Pro Unibody enclosure and bottom cover make a terrific shielding system. One of the connectors in this system touches the bottom plate right in the center where it flexes a lot. When the computer heats up, the metal pins in the connector scrape noisily against the cover and chassis. It makes you want to eat your hands. By removing the connector (two easy screws!), you remove one of the grounding connections between the unibody enclosure and the bottom cover. Don't worry: there are plenty of other connections, and they are adequate for the purpose."
