WD Purple's exclusive firmware upgrades work with ATA streaming to reduce error pixilation and video interruptions that occur when desktop hard drives are incorrectly used as storage in security systems. WD Purple Surveillance Storage is built for 24/7, always-on, high-definition surveillance security systems that use up to eight hard drives and up to 32 cameras.
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. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.

• 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. These drives are designed to replace standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance environment. Desktop drives are built to run for only short intervals and are not engineered to withstand high-temperature fluctuations and equipment vibrations found in a typical surveillance application.
• 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. WD Purple Surveillance Storage is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most. Experience the security of knowing you're using a surveillance - class drive designed by a leader in the hard drive industry.
• 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. When you invest in a premium surveillance-class drive you worry less while enjoying the benefits over a longer period of time.
