Western Digital has been busy customizing its hard drives.

A month ago, the company introduced what it called the first green 2TB enterprise hard drive aimed at data centers. Now it's making another drive specifically for audio and video applications, and also the surveillance market.

The company announced Tuesday the new 2TB WD AV-GP. It incorporates Western Digital's AV Intelligent Drive Technology, which makes it a good choice for AV applications such as DVRs, media centers, media servers, and surveillance video recording.

The drive is designed to better withstand high temperatures for long periods of time while remaining quiet during operation. The new drive's features also include:

  • Ultra-low power consumption: By supporting the combination of WD's IntelliSeek, IntelliPark, and IntelliPower technologies, WD claims that the new AV-GP hard drive has reduced power consumption by up to 40 percent compared with competitors' drives. However, this also means the drive has no spinning specification, which generally determines its throughput performance. As a result, the drive is not intended for applications that require high performance.
  • Compatibility: The new WD AV-GP has been tested for compatibility in a broad range of AV products including set-top boxes, DVD recorders, and mainstream surveillance systems.
  • SilkStream: This is the main feature that separates the WD AV-GP from others. The drive is optimized for smooth, continuous digital video playback of up to 12 simultaneous HD streams. According to Western Digital, SilkStream is compatible with the ATA streaming command set so customers can use standard streaming management and error recovery options.
  • Preemptive Wear Leveling: The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications.

Though optimized for AV applications, the WD AV-GP uses the SATA interface and would work anywhere this interface is used, such as a desktop computer.

The 2TB WD AV-GP hard drive, model WD20EVDS, is available now for an estimated price of $299.
