[. . . ] · Long-term reliability ­ These drives are designed to last in high temperature, always-on, streaming digital audio/video environments. Ideal for set top boxes, media servers, media centers, and mainstream surveillance systems. · Reduced power consumption ­ With the combination of WD's IntelliSeekTM, IntelliParkTM, and IntelliPowerTM technologies, WD has reduced power consumption by up to 40 percent compared to competitors' drives. · Quiet ­ Noise levels have been optimized to less than one sone* ­ virtually below the threshold of human hearing. Technology Features SilkStreamTM ­ Optimized for smooth, continuous digital video playback of up to twelve simultaneous HD streams. SilkStream is compatible with the ATA streaming command set so CE customers can use standard streaming management and error recovery options. IntelliSeek ­ Calculates optimum seek speeds to lower power consumption, noise, and vibration. IntelliPower ­ A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. IntelliPark ­ Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag. [. . . ] 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. *A sone is a subjective unit of loudness as perceived by a person with normal hearing.
