WD AV GP 2 TB Desktop Internal Hard Drive WD20EURS

24x7 reliability. These drives are designed to last in always-on, streaming digital audio/video environments such as PVRs, DVRs and surveillance video recorders.	Reduced power consumption. With the combination of WD's IntelliSeek, IntelliPark, and IntelliPower technologies, WD has reduced power consumption by up to 40 percent compared to competitors' drives.	Whisper quiet. Noise levels have been minimized to less than one sone – virtually below the threshold of human 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 so CE customers can use standard streaming management and error recovery options. IntelliSeek. Calculates optimum seek speeds to lower power consumption, noise and vibration. View demo * A sone is a subjective unit of loudness as perceived by a person with normal hearing.

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. Advanced Format Technology (AF). Technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. (EURS models only)

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.
