WD 500GB 3.5"" Features

• Highest capacity for audio/video storage: WD AV-GP SATA drives now offer unrivaled 500GB storage capacity - perfect for today's storage intensive applications
• 24x7 reliability: These drives are designed to last in high temperature always-on streaming digital audio/video environments such as PVR/DVR, IPTV and video surveillance systems
• Compatible: Tested for compatibility in a broad range of AV products including set top boxes, DVR/PVR and mainstream video surveillance systems
• Reduced power consumption: This drive consume less power by up to 40 percent compared to 7200 RPM hard drives. Lower power means less heat and greater reliability
• Quiet: Noise levels have been minimized to less than one sone - virtually below the threshold of human hearing
• 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
• IntelliPower: A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance
• IntelliPark: 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 (PWL): The drive arm frequently sweeps across the disk to reduce uneven wear on the drive surface common to audio video streaming applications
• 1 million hours MTBF: Best-in-class reliability for mainstream 3.5-inch form-factor AV storage
