What is the difference between a desktop drive and a WD Purple drive?
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.
Improve performance with AllFrame
WD Purple surveillance-class hard drives are equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increases the number of drive bays supported. AllFrame reduces video interruptions that commonly occur when desktop hard drives are incorrectly used as storage in security systems. Missed frames and lost footage is a serious problem when an event occurs and surveillance footage needs to be retrieved. WD Purple with AllFrame provides the confidence you should expect when it's time to play back and review critical surveillance footage.
Key benefits:
• Reduces video frame loss with surveillance-class storage.
• Specifically tuned for surveillance security systems.
• Caching algorithms are tuned for write-intensive, low bit rate, high stream count applications that are typical of surveillance applications.
• Priority change for write allocations and preemptive caching policies.
• TLER & ATA streaming support.
• Supports up to eight drives.
Low 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.
Expand Your View to 32
WD Purple drives are optimised to support up to 32 cameras, giving you flexibility to upgrade or expand your security system.
