Reduced power consumption
Environmentally responsible
Cool and quiet
WD Caviar GP drives use less power and support quieter, cooler-running desktop PCs and external storage devices.
Overview
As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar GP makes it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.
Key Features
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.
Helps enable eco-friendly PCs - WD Caviar GP drives yield average drive power savings of 4-5 watts over competitors’ drives making it possible for our energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation. This power savings equates to reducing CO2 emission by up to 13.8 kilograms per drive per year - the equivalent of taking a car off the road for 3 days each year*. By using environmentally-conscious PCs with our WD Caviar GP drives on board, large organizations with many desktop computers can minimize their carbon footprint and save real money on electricity costs.
*Assumes that a car produces 1.60 CO2 pounds per Kwatt/hours/year. Calculation of automobile emissions depends on the car's g/km emission levels and km/year of driving.
Cool and Quiet - 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 GP drive, the coolest and quietest in its class. External drives with WD Caviar GP drives on board can save up to $14.00 per year in electricity costs. See our power savings chart for details.
IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance. Additionally, GreenPower 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. View demo >
IntelliPark - Delivers lower power consumption by automatically unloading the heads during idle to reduce aerodynamic drag.
Perpendicular Magnetic Recording (PMR) - Employs PMR technology to achieve even greater areal density.
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. (750 GB and 1 TB only)
Ideal For
PCs, external storage, and other devices that require lower power consumption and cool, quiet operation.
