WD Purple Surveillance Hard Drives - 1 to 4 TBs

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.

• 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.
