Irvine, Ca. based WD, a Western Digital company, launched its entrance into the surveillance specific drive market today with a new line of HDDs named WD Purple. These 3.5" drives are designed specifically to address the unique requirement of CCTV applications that are always-on and write intensive. With capacities up to 4TB they are capable of supporting 32 high definition cameras.
WD Purple drives can be stacked in an eight bay array, which according to Ying Yang, director of testing, Hikvision, adds "flexibility to expand for future system coverage". In addition to increased flexibility, the company's proprietary AllFrame technology implemented in WD Purple protects against pixilation and dropped frames.
Pricing for these drives range from an MSRP of $89.99 for a 1TB to $199.99 for 4TB. With several options to choose from, WD has launched a compatibility selector tool to assist customers with their drive selection at: http://www.wd.com/en/products/products.aspx?id=1210.
