Product Description
4TB Purple 5400 rpm SATA III 3.5" Internal Surveillance Hard Drive from WD is designed to withstand the stresses placed on it in a 24/7, always-on, high-definition surveillance system with 16 drive bays. With support for up to 64 high-definition surveillance cameras, this 4TB hard drive can hold a large amount of data and gives you the ability to easily upgrade and expand your security system.
