WD Drives Equipped for Surveillance System Environments
The drives, which are designed with tarnish-resistant components, include exclusive firmware upgrades that protect against video pixilation.Storage specialist WD launched the Purple NV, a purpose-built line of 3.5-inch, high-capacity 4TB and 6TB hard drives designed for scalable network video recorder (NVR) surveillance systems. The drives are intended for larger-scale network surveillance systems utilizing higher hard drive bay counts and greater numbers of attached cameras, along with the resultant increase in data created. "Surveillance systems are different from standard PCs in that the application is different. Surveillance systems primarily write to the hard drive where PC systems tend to have a more equal mix of reading and writing," Darrin Bulik, director of product marketing for WD's storage technology business unit, told eWEEK. "In order to provide the best storage solution for a surveillance system that can have a high number of streams from the associated cameras as well as take into account the high write intensive environment and higher number of drives in a system, WD has the WD Purple family of surveillance HDDs." When combined with ATA streaming support, AllFrame technology helps to reduce video footage loss with a proprietary cache policy management technology to help improve data flow and playback.
In addition, the drives, which are designed with tarnish-resistant components, include exclusive firmware upgrades that protect against video pixilation and interruptions within a surveillance system.
