The 160 GB 3.5" IDE-PATA Internal Drive from Western Digital incorporates SilkStream technology with whisper-quiet acoustics and thermally optimized operation. With 7200 RPM and design advances, this drive offers reliability and low cost for video recording devices.
PATA Interface
Although most systems use hard drives with a SATA interface, some unique or legacy systems require drives with a PATA interface.
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.
Quiet
Noise levels have been minimized to less than one sone* - virtually below the threshold of human hearing.
Note:
* A sone is a subjective unit of loudness as perceived by a person with normal hearing.
Compatible
Tested for compatibility in a broad range of AV products including set top boxes, DVD recorders and mainstream surveillance systems
SilkStream
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.
Note:
*Assumes Host Transfer Block size of 2 MB per stream.
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
The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications. Western Digital's AV PATA drive is ideal for PVR/DVR, DVD recorders, surveillance video recorders and other video streaming applications.
1 Million Hours MTBF
Best-in-class reliability for mainstream 3.5" form-factor AV storage.
