Western Digital AV-GP - Energy Saving 3.5" Hard Drive for Multimedia Applications with Advanced Format Technology Reliability for continuous video transmission Using WD GreenPower Technology™, the energy-saving WD AV-GP SATA drive meets the requirements for continuous operation (24x7) in demanding audio and video environments. With up to 40 percent lower power consumption, this drive delivers cool, quiet operation and reliability – ideal for audio/video applications such as PVRs, DVRs, set-top boxes (STBs) and surveillance video recording. Advanced Format technology enables higher drive capacities and increases the efficiency of media formats. Greatest energy savings were the first priority in the development of GreenPower drives. They are characterised by extremely reduced energy consumption, low noise and temperature development and consistently high performance. GreenPower Drive With up to 40% energy savings, the drive delivers the lowest noise and temperature during continuous operation, and its high reliability makes it particularly suitable for audio and video applications such as PVR, DVR, digital receivers and video surveillance systems. Sustained reliability The WD AV-GP drive ensures continuous data flow for uninterrupted playback of audio and video files even at high ambient temperatures and continuous operation. Reduced power consumption. WD has reduced the energy requirements of its GreenPower drives by up to 40% over third-party products using IntelliSeek™, IntelliPark™ and IntelliPower™ technologies. Low noise The noise has been optimised to less than one sone* and is therefore almost imperceptible to human hearing. *A Sone is the subjective unit of measurement of the volume that is perceived by a person with average sense of hearing. WD AV-GP The high-capacity surveillance drive enables higher resolution and uses less power for greater reliability. The WD AV-GP drive allows surveillance systems with two or more cameras to capture much clearer footage and store more video. In addition to the possible clearer images, the WD AV-GP is also ideal for high-performance video surveillance systems because of its long-term reliability and low power consumption. With an MTBF of one million hours, this drive is designed for high temperatures, continuous operation and streaming of digital security video recordings WD Intelligent Drive Technologies: Representation of IntelliSeek™ technology IntelliSeek™ Calculates the optimal search speed to reduce power consumption, as well as reduce noise and vibration. SilkStream™ Provides smooth, uninterrupted digital video performance and supports playback of up to twelve simultaneous HD streams. SilkStream™ is compatible with the ATA Streaming Command Set, allowing CE customers to continue using standard streaming management and troubleshooting options. Preemptive Wear Leveling (PWL) The drive arm travels regularly across the entire disk to prevent uneven wear and tear of the drive surface that occurs during audio and video streaming. IntelliPark™ IntelliPark™ Reduces power consumption during idle by automatically demagnetizing the read heads to reduce aerodynamic resistance, as well as by turning off the reading and writing electronics. IntelliPower™ Ensures optimal speed coordination with transfer rate and cache algorithms to achieve significant power savings without sacrificing performance. Advanced Format Technology Advantages of Advanced Format Technology Advanced Format technology allows hard drive manufacturers to develop new drives with higher storage density and capacity. By using longer ECC code words, Advanced Format technology improves burst error correction by 50%. Advanced Format Disks use Advanced Format blocks with 4,096-byte sectors, each composed of eight logical 512-byte blocks. To ensure compatibility with PCs and servers, including hard disk recorders, PSP consoles and mobile phones, Advanced Format disks emulate a 512-byte device by passing 512-byte blocks to the disk interface. Advanced Format technology is tailored to the latest operating systems such as Windows® Vista, Windows® 7 and Mac® OS X. For users who still use Windows XP, Western Digital offers WD Align software a simple tool that unlocks the full performance of advanced format drives even under Windows XP. Compatible Tested for compatibility with a wide range of AV products, such as set-top boxes, DVD recorders and popular surveillance systems. WD hard drives are "ready" for upgrading or integrating Windows® 7 Western Digital hard drives, the world's leading internal and external hard drives are certified Windows® 7 compatible.
