Features
Long-term Reliability - These drives are designed to last in high temperature always-on streaming digital audio/video environments such as PVR/DVR, DVR recorders and surveillance video recorders.
Reduced Power Consumption - WD has reduced power consumption by up to 40 percent compared to competitors' drives with the combination of WD's IntelliSeek, IntelliPark, and IntelliPower technologies.
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.
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)
