Hey there, amitsharma227!
The WD Black is actually our performance drive and it is designed to deliver on the demanding usage in gaming and/or video/photo editing rigs. However, since those 7200 RPM are not enough for you, I can also suggest you to take a look at the WD VelociRaptor. This HDD is designed for high-performance computing with 10 000 RPM and 64 MB cache and it might be able to deliver on what you are looking for. It can hold the data-intensive workloads of demanding software applications as well as high-end gaming. Just like the WD Black, it offers a limited 5-year warranty as well.
You can check more details about the WD VelociRaptor here:

Hope you find what you are looking for!
Best of luck!
