About WD AV-GP
The WD AV-GP 3TB Internal Hard Drive is designed for 24x7 operation in higher temperature environments. The WD AV-GP drive is able to capture up to 12 HD video streams simultaneously, making them a good choice for DVR or video surveillance duty. It actually uses the SATA II 3.0Gbp/s interface on the 3TB Caviar Green (although it can't saturate either one). The 3TB AV-GP has a four-platter design with 750GB/platter capacity.
