Hey there, Malek Agha!
I would agree with USAFRet on this one.
The drive you've selected is a part of our Datacenter series and it's supposed to be used for heavy storage solutions in servers, surveillance and cloud storage.
The WD Re will give you a pretty amazing performance in a server, but I'm not sure you will be able to experience its full potential on a computer as a standalone drive.
I'd recommend checking out WD Black for example.
It's again 7200 RPM with 64 MB cache, specifically designed for performance and high-end applications in all PCs. Mostly used for gaming and demanding software apps.
You can see more details about it here:

If you have more questions, let me know!
