Desktop drives vs. surveillance-class storage You wouldn\'t use a bicycle to transport cargo across the country because it\'s not the right tool for the job. You also shouldn\'t use a desktop hard drive in your surveillance security system because it wasn\'t designed for that application. WD Purple surveillance-class storage has been tested to be compatible in a wide-range of security systems. Surveillance storage for peace-of-mind Whether you\'re protecting your personal assets and loved ones or monitoring the business you worked hard to build you can rely on surveillance-class storage built by one of the largest hard drive manufacturers in the world. Lower power consumption Low power consumption is crucial in high-temperature always-on surveillance environments. With exclusive IntelliSeek technology WD Purple drives calculate the optimum seek speeds which lowers power consumption noise and vibration that can damage and cause desktop drives to wear out more quickly..
