The WD Purple WD20PURX is a 2 TB hard drive engineered specifically for continuous operation in high-definition security systems. Its exclusive AllFrame technology and ATA streaming firmware work together to reduce the pixelation and video dropouts that occur when standard desktop drives are incorrectly used inside DVR or NVR systems.

The WD20PURX is certified for use in systems with up to 8 simultaneous hard drives and up to 32 cameras, making it a practical choice for expanding surveillance setups in homes or small to medium businesses.
