Long-Term Reliability With a MTBF of 1 million hours, these drives are designed to last in high temperature always-on streaming digital audio/video environments such as PVR/DVR, DVR recorders & surveillance video recorders Quiet Noise levels have been minimized to less than one sone (A sone is a subjective unit of loudness as perceived by a person with normal hearing)
- virtually below the threshold of human hearing Low Power Consumption WD AV drives deliver best-in-class low power consumption for reduced system power requirements & increased reliability. Note: 3.3V SATA power is not available in this exclusive product Compatible Tested for compatibility in a broad range of AV products including set top boxes, DVD recorders, & mainstream surveillance systems Silk Stream Optimized for smooth, continuous digital video playback of up to twelve simultaneous HD streams (Assumes Host Transfer Block size of 2 MB per stream). Silk Stream is compatible with the ATA streaming command set so CE customers can use standard Intelli Seek Calculates optimum seek speeds to lower power consumption, noise & vibration Ramp Load Parks the recording heads off the disk surface during spin up, spin down & when the drive is off. This ensures the recording head never touches the disk surface resulting in enhanced long term reliability due to less head wear, & enhanced n 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 Technical
