SONY VAIO 14inch touch screen laptop

This is the laptop I want to buy

Sony VAIO 14" TouchScreen Laptop 8GB Memory 1TB Hard Drive SVE14A27CXH - Best Buy

Does anyone have any experience with this laptop? Also My question is how do I change the hard drive in sony laptops. I have a sony vaio S series 13.3 inch laptop. I know that Sony has a hard drive protection safety guard. When you shake the laptop it secures the hdd in place. I assume all Sony's would have this.

QUESTION: In the link, the sony vaio E series laptop comes with a 1TB hdd. I want to switch it to a 512 gb SSD. How do I do that? And will the safety pin or hard drive safety guard be applied to the new hard drive? Is their a video that shows the process of this?

Any help will be appreciated.

Thanks,
