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 rigorously tested to be adjusted in a wide-range of security systems. These drives are intended to substitute standard desktop drives that were not designed for the harsh 24/7 always-on, high-definition surveillance situation. Desktop drives are constructed to run for only short intervals and are not engineered to endure high-temperature fluctuations and equipment vibrations found in a typical surveillance application.

You can Always Rely on WD PURPLE

Incredible WD PURPLE Features

Everyday Performance

All Frame Technology - Reduced Frame Loss

All WD PURPLE surveillance-class HDD’s feature AllFrame Technology which works with ATA streaming to reduce the frame loss of footage, improve playback and also increase the number of drive bays that can be supported. WD AllFrame reduces video interruptions that often 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 Technology provides the confidence you should expect when it’s time to play back and review critical surveillance footage.
