As hard drive capacities increase, the power required to runthose drives increases as well. WD Caviar Green makes it possiblefor energy-conscious customers to build systems with highercapacities and the right balance of system performance, ensuredreliability, and energy conservation.
Key Features
Advanced Format - Advanced Formatting optimizeshard drives to take advantage of the capabilities of neweroperating systems.
Reduced power consumption - By adjusting therotational speed, using bigger data buffers, parking the drive'shead, and optimizing how the drive seeks and caches data we havereduced the power consumption by up to 38 percent.
Helps enable eco-friendly PCs - WD Caviar Greendrives yield average drive power savings of 4-5 watts overcompetitors' drives making it possible for our energy-consciouscustomers to build systems with higher capacities and the rightbalance of system performance, ensured reliability, and energyconservation. This power savings equates to reducing CO2 emissionby up to 13.8 kilograms per drive per year - the equivalent oftaking a car off the road for 3 days each year*. By usingenvironmentally-conscious PCs with our WD Caviar Green drives onboard, large organizations with many desktop computers can minimizetheir carbon footprint and save real money on electricitycosts.
*Assumes that a car produces 1.60 CO2 pounds perKwatt/hours/year. Calculation of automobile emissions depends onthe car's g/km emission levels and km/year of driving.
Perfect for green external drives - ExternalUSB, FireWire and Ethernet drives with WD Caviar Green drives onboard can save up to $14.00 per year in electricity costs dependingon the power-on-hours and power supply efficiency.
As an added benefit, external drive manufacturers can eliminatethe need for a fan in a high-capacity product with this drive, thecoolest and quietest in it's class.
IntelliPower™ - A fine-tuned balance ofspin speed, transfer rate and cache size designed to deliver bothsignificant power savings and solid performance.
IntelliSeek™ - Calculates optimum seekspeeds to lower power consumption, noise and vibration.
IntelliPark™ - Delivers lower powerconsumption by automatically unloading the heads during idle toreduce aerodynamic drag.
Perpendicular Magnetic Recording (PMR) -Employ PMR technology to achieve even greater areal density.
StableTrac™ - The motor shaft is securedat both ends to reduce system-induced vibration and stabilizeplatters for accurate tracking, during read and writeoperations.
Ideal For
Environmentally conscious PCs requiring lower power consumption andcool, quiet operation.
unfortunately, when it comes to WD, Green=slow! just to save like 3 watts power!
i'd rather buy a faster drive and save more power by turning off the lights/air con/heater etc
