Designed for 24x7 audio and video environments.

WD AV hard drives take advantage of significant design advances in WD’s storage technology by incorporating SilkStream™ streaming with whisper-quiet acoustics, 7200 RPM performance, and thermally optimized operation. These design advances enable unparalleled reliability and low cost of ownership for manufacturers of digital video recording devices.


24x7 reliability
With a MTBF of 1 million hours, these drives are designed to last in always-on streaming digital audio/video environments such as PVR/DVR, DVR recorders, and surveillance video recorders.

Noise levels have been minimized to less than one sone – virtually below the threshold of human hearing.

PATA or SATA interface
Although most systems use hard drives with a SATA interface, some unique or legacy systems require drives with a PATA interface.

Tested for compatibility in a broad range of AV products including set top boxes, DVD recorders, and mainstream surveillance systems.

Optimizes seek speeds to lower power consumption, noise and vibration.

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

1 million hours MTBF
Best-in-class reliability for mainstream 3.5-inch form-factor AV storage.

Ramp Load
Parks the recording heads off the disk surface during spin up, spin down, and when the drive is off. This ensures the recording head never touches the disk surface resulting in improved long term reliability due to less head wear, and improved non-operational shock tolerance.

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.


This drive is compatible with any server that accepts 3.5"x1.0" (LFF) 40-pin EIDE (Ultra ATA100) drives.
