Western Digital WD5000AACS Техническое Руководство

• 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.

• IntelliPark

– Delivers lower power consumption by

automatically unloading the heads during idle to reduce
aerodynamic drag.

Based on WD’s exclusive GreenPower

™

technology, these drives are

designed to deliver power savings as the primary attribute. As hard
drive capacities increase, the power required to run those drives
increases as well. 1 TB hard drives currently available have a typical
power consumption rating greater than 13.5 watts. WD Caviar Green
drives yield an 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.

In desktop computers this power savings equates to reducing CO

2

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.
