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.

WD AV-GP Features

  • 24x7 reliability: These drives are designed to last in always-on, streaming digital audio/video environments such as PVRs, DVRs and surveillance video recorders
  • Reduced power consumption: With the combination of WD's IntelliSeek, IntelliPark and IntelliPower technologies, WD has reduced power consumption by up to 40 percent compared to competitors' drives
  • Whisper quiet: Noise levels have been minimized to less than one sone - virtually below the threshold of human hearing
  • Compatible: Tested for compatibility in a broad range of AV products including set top boxes, DVD recorders and mainstream surveillance systems
  • IntelliPark: Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag
  • Long-Term Reliability: This drive is designed to last in high temperature always-on streaming digital audio/video environments such as PVR/DVR, DVR recorders and surveillance video recorders
  • SilkStream: Optimized for smooth, continuous digital video playback of up to twelve simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so CE customers can use standard streaming management and error recovery options
  • Preemptive Wear Leveling (PWL): The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications
  • IntelliSeek: Calculates optimum seek speeds to lower power consumption, noise and vibration
