Product Description

As hard drive capacities increase, the power required to run those drives increases as well. WD Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.

Main Features:

  • Reduced power consumption - WD has reduced power consumption by up to 40 percent compared to standard desktop drives with the combination of WD's IntelliSeek, NoTouch, and IntelliPower technologies
  • Helps enable eco-friendly PCs
  • WD Caviar Green drives on board, large organizations with many desktop computers can minimize their carbon footprint and save real money on electricity costs
  • Cool and quiet, WD GreenPower Technology yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives
  • Perfect for external drives - External drive manufacturers can eliminate the need for a fan in a high-capacity product with a WD Caviar Green drive, the coolest and quietest in its class
  • IntelliPower - A fine-tuned balance of spin speed, transfer rate, and caching algorithms designed to deliver both significant power savings and solid performance. Additionally,
  • WD Caviar Green drives consume less current during startup allowing lower peak loads on systems as they are booted
  • IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise, and vibration
  • NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit
  • StableTrac - The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations. (2 TB model only)
  • Native Command Queuing (NCQ) - Server feature for performance in random I/O transaction environments. It aggregates many small random data transfers and allows the disk to reorder the commands in a sequential order for faster access
  • Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density
  • Low power spin-up - WD Caviar Green drives consume less current during startup allowing lower peak loads
  • Advanced power technology - Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability
