A quote from the article at PCW:
WD has made the drives complaints with the latest US eco-standard Energy Star 4.0. The first to launch will be the 1TB Caviar GP, used in the My Book series of external hard drives.
New features incorporated in the drives to reduce power consumption are:
- Balancing spin speed, transfer rate and cache size (IntelliPower)
- Unloading the heads during idle to reduce aerodynamic drag (IntelliPark)
- Optimizing seek speed to reduce noise and vibration (IntelliSeek)
The GreenPower family includes drives for Enterprise, Home-users, and consumer electronics.
Western Digital goes green, offers 1TB drives (Ars Technica)
