 Ideal for video surveillance storage

The new Western Digital Purple line of hard drives are designed specifically for surveillance systems. These drives are built to be compatible with industry-leading chassis and chip set manufacturers for seamless integration into your new or existing video surveillance system. Optimized to support up to 32 high-definition cameras makes this drive ideal for personal, home office or small business surveillance systems.

AllFrame Technology

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.

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.
