When we throw other modern high performance desktop hard drives into the mix, you get a sense of just how noisy the VelociRaptor 1TB is during seek. Against the quietest 7200 RPM models, the VelociRaptor's measured noise level was 10 dB higher, even after being taken out of the IcePack. On the bright side, its power consumption and vibration level is fairly good for its capacity, more or less the same as the 600GB version.

The physical characteristics of the new Scorpio Blue 500GB are simply top notch. Its noise level and energy efficiency is first class, undoubtedly thanks to its single platter design. In particular, the drive's power consumption in seek is unbeatable. Many drives in the past have tried and failed to get below the 2W mark, while the Scorpio Blue consumed closer to 1.5W.
