About WD AV-25

The WD AV-GP 250GB SATA hard drive delivers 24x7 quiet operation, low temperature, high reliability and optimized streaming with a storage capacity of 250GB for storage intensive AV applications such as PVRs, DVRs, set top boxes and surveillance video recording. Furthermore with the combination of WD's IntelliSeek, IntelliPark and IntelliPower technologies, they have reduced power consumption by up to 40 percent compared to competitors' drives.

WD AV-25 Features

  • 24x7 reliability: This drive is designed to last in always-on streaming digital audio/video environments such as DVR/PVR, digital video surveillance and other demanding multimedia applications
  • SilkStream technology: Optimized for smooth, continuous digital video playback of up to five simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so AV customers can use standard streaming management and error recovery options
  • Quiet: Noise levels have been minimized to less than one some - virtually below the threshold of human hearing
  • 1 million hours MTBF: Best-in-class reliability for small-form factor AV storage
  • Advanced Format Technology: Leading edge technology delivers improved video quality and AV performance through enhanced error correction capability
  • Ultra-cool operation: A cool drive is a more reliable drive. WD continues to develop new and innovative ways to keep drives cool while they are operating
  • Low power consumption: The drive draws less than 2 Watts while operating and a mere 4.75 Watts during spin up
  • 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
