Well the WD Black drives have the Vibration Control Technology (VCT) which helps the disk to endure and adapt to any mounting problems and system induced vibrations, resulting in increased data accuracy, performance and reliability over time. It also has a High Resolution Controller (HRC) with an improved architectural design, which increases data precision across the hard drive. The new generation of the WD Black drives also has a Corruption Protection Technology, which prevents and limits data loss caused due to power failure. You could also take a look at all the features on the website as well.
Edit: If you plan to OC, it's a good idea to get a CPU cooler.
