AV Hard Drives


Highest capacity for
audio/video storage

WD AV SATA drives now offer unrivaled storage capacity up to 4 TB – perfect for today’s storage intensive applications.

24x7 reliability

These drives are designed to last in high temperature always-on streaming digital audio/video environments such as PVR, DVR and IPTV systems.


Optimized for smooth, continuous digital video playback of up to 16 simultaneous HD streams.* SilkStream is compatible with the ATA streaming command set so CE customers can use standard streaming management and error recovery options.

Low power consumption

WD AV drives consume less power by up to 40 percent compared to 7200 RPM hard drives. Lower power means less heat and greater reliability.

Low Capacity and 2.5-inch Surveillance

WD AV drives offer 500 GB and lower capacities suitable for low profile entry level surveillance systems requiring reliability in always-on environments.


Calculates optimum seek speeds to lower power consumption, noise, and vibration.


A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. (3.5-inch models only)

Advanced Format Technology

Leading edge technology delivers improved video quality and AV performance through enhanced error correction capability. (EURS/EURX/AUDX/xxCT models only)

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.


Noise levels have been minimized to less than one sone** - virtually below the threshold of human hearing.
**A sone is a subjective unit of loudness as perceived by a person with normal hearing.

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.

Examples of the number of photos, songs, videos and any other files that can be stored on a hard drive are provided for illustrative purposes only. Your results will vary based on file size and format, settings, features, software and other factors.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
