As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green 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.
Reduced power consumption - By adjusting the rotational speed, using bigger data buffers, parking the drive's head, and optimizing how the drive seeks and caches data we have reduced the power consumption by up to 38 percent.
Helps enable eco-friendly PCs - WD Caviar Green 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 Green 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.
Perfect for "green" external drives - External USB, FireWire and Ethernet drives with WD Caviar Green drives on board can save up to $14.00 per year in electricity costs depending on the power-on-hours and power supply efficiency.
As an added benefit, external drive manufacturers can eliminate the need for a fan in a high-capacity product with this drive, the coolest and quietest in it’s class.
IntelliPower™ - A fine-tuned balance of spin speed, transfer rate and cache size designed to deliver both significant power savings and solid performance. For each GreenPower drive model, WD uses a different, invariable RPM. Throughout the product line, RPM ranges between 5400 and 7200.
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.
Perpendicular Magnetic Recording (PMR) - Employ 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. (750GB and 1TB only)
