As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar 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.
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, IntelliPark, and IntelliPower technologies.
Helps enable eco-friendly PCs
WD Caviar Green drives yield an average drive power savings of 4-5 watts over standard desktop 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.
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. External drives with WD Caviar Green 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, 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.
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.
