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 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.

The WD Purple Surveillance Hard Drive is designed for high temperature, always-on, surveillance security systems to ensure reliability and quality video play back when you need it most.

This WD Purple Surveillance-class hard drive is equipped with AllFrame technology which works with ATA streaming to reduce frame loss, improve playback and increase 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 can be a 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.

With support for up to 64 high-definition surveillance cameras, this WD Purple hard drive gives you the flexibility to upgrade and expand your security system in the future.

In terms of speed, this drive operates using WD's IntelliPower rotational speed. This means that the rpm speed of the drive depends on the operations being performed. If the drive is performing mostly sequential reads and writes, its speed will be increased as compared to if it were performing mostly random mode operations. This 6TB drive also features a 64MB cache helps ensure uninterrupted data transfers.

With integrated IntelliSeek technology, this WD Purple drive calculates the optimum seek speed which lowers power consumption, noise and vibration that can damage and cause drives to wear out more quickly.

1 million hours mean time between drive failures

Compatible with Windows 8, 7, Vista, and XP
Compatible with Mac OS X Mountain Lion, Lion, and Snow Leopard

Please bear in mind that Windows XP does not support drives with capacities greater than 2TB. Compatibility may vary depending on user's hardware configuration and operating system
