WD Caviar® GP
WD10EACS
SATA Hard Drives
1 TB, SATA 3 Gb/s
Reduced power consumption
Environmentally responsible
Lower cost of ownership
WD Caviar GP drives support quieter, cooler-running desktop PCs and external
storage devices that conserve critical power resources.
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 - 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 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.
Perfect for "green" external drives - External USB, FireWire and Ethernet drives
with WD Caviar GP drives on board can save up to $14.00 per year in electricity
costs depending on the power-on-hours and power supply efficiency. See our power
savings chart for details.
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.
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) - 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. (750 GB and 1 TB only)
Ideal For
Environmentally conscious PCs requiring lower power consumption and cool, quiet
operation.
