Upgrading Laptop Harddrive

I recently bought a high end Samsung NP550 Laptop (core i17 3610QM, 8GB,GT 650M). But it has a 5400 rpm hard drive which is causing the system to be slow. See my previous post
I am looking for upgradation to a fast Harddrive (Not SSD). Can anyone suggest which is the fastest laptop hard drive out there ?? Are 10000 rpm harddrives available for laptops ?? Where can I buy them in India. flipkart doesnt seem to be good in this regard.
