3.5" SATA III 2TB 6Gb/s 64MB WD20PURZ WD HDD

WD20PURZ hard drives are designed for use in video surveillance systems operating in a rigorous 24x7 mode. They offer excellent performance, high capacity and long-term reliability. The drives are designed for non-stop operation in audio/video processing equipment, such as DVRs and recorders in PC-based CCTV systems.

The WD20PURZ is dedicated to heavy-duty systems, while providing greater resistance to vibration and elevated temperatures with lower power consumption and lower noise emissions, thanks to IntelliSeek, IntelliPark and IntelliPower technologies. Western Digital drives are recommended by all leading manufacturers of CCTV equipment.

WD20PURZ drives have significantly better performance than their counterparts dedicated to PC workstations. Among those of key importance are:

• 25% lower average standby time (14.5 ms),
• noise emissions reduced by up to 20%,
• and reduced power consumption for full operation by as much as 50%.

DVRs using more drives typically record on one of them while the others are in sleep mode. The power consumption of the WD AV-GP drive in sleep mode is only 0.4W, which is 40% of the power consumption in this mode compared to standard drives.
