Western Digital Pounces on Surveillance Storage Market with Purple Hard Drives

Purple is the new color of surveillance

Western Digital continues the trend of color coding its hard drive line by adding a Purple model built specifically for surveillance applications. The Purple line differs from regular hard drives in that they're better suited for 24/7 always-on conditions, whereas standard HDDs are built to run for only short intervals, WD says. In addition, Purple drives can withstand high temperature fluctuations and equipment vibrations inherent in typical surveillance applications.

Outside of ruggedness, WD's Purple family uses AllFrame technology, which helps to reduce video footage loss with a proprietary cache policy management technology that's intended to help improve data flow and playback.

"Different from ordinary desktop hard drives designed for eight hours of daily operation, WD Purple drives have the built-in reliability to operate in Hikvision home and small business system installations so critical video footage is available when it is needed most," said Ying Yang , director of testing, Hikvision. "An additional benefit of WD Purple drives is they support up to eight drives and 32 HD cameras so there is the flexibility to expand for future system coverage."

The Purple line consists of 3.5-inch HDDs with 64MB of cache and a SATA 6Gbps interface. They come in 1TB, 2TB, 3TB, and 4TB capacities ranging in price from $90 to $200 MSRP.
