The 500GB Caviar Green Internal Hard Drive from Western Digital is an internal hard drive, designed with energy-efficiency and quiet operation in mind. It features a SATA interface and standard 3.5" form factor for installation in desktop computers.
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
Note:
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
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
IntelliPower
IntelliPower is 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
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
Use Scenarios
Ideal for PCs, external storage, and other devices that require lower power consumption and cool, quiet operation
