Desktop drives vs. surveillance-class storage – WD 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 hard drives are designed for high-temperature, always-on, surveillance security systems to ensure reliability and quality video playback 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.

Improve performance with AllFrame – WD 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 Surveillance Storage 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.

Lower power consumption – Low power consumption is crucial in high-temperature always-on surveillance environments. With exclusive IntelliSeek technology, WD Surveillance 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.

Optimized performance for up to 32 HD cameras – These hard drives are optimized to support up to 32 high-definition surveillance cameras, giving you the flexibility to upgrade and expand your security system in the future.
