WD Caviar Green – Cool, quiet, eco-friendly.
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.

 WD Caviar Green drives use less power and support quieter, cooler-running desktop PCs and external storage devices.  |
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, NoTouch, 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.
Cool and quiet - WD GreenPower Technology™ yields lower operating temperatures for increased reliability and low acoustics for ultra-quiet PCs and external drives.
Massive capacity - Capacities up to 2 TB offer the most available capacity for storage-intensive programs and space-hungry operating systems, like Windows Vista®, with plenty of room left over for photos, music, and video.
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.

 PMR |
IntelliPower - A fine-tuned balance of spin speed, transfer rate and caching algorithms designed to deliver both significant power savings and solid performance.
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. (2 TB models only)
Low power spin-up - WD Caviar Green drives consume less current during startup allowing lower peak loads.
Advanced power technology - Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability.
At any rate, after formatting these drives and doing a series of tests for integrity, these seem to be up to the standard of all the other Western Digital drives I've purchased in the past. They run on low power, cool, and very quiet - the fan in the external enclosure is far louder than both these drives combined. Copying data to and from the drive was flawless, and, while not as fast as many other drives on the market, if you're looking to save power and/or it's going into an external enclosure anyway (and speed doesn't matter much), then these really drives can't be beat.
Would highly recommend. The only "problem" with Western Digital drives are they last TOO long. As I write this, I have 4 WD drives next to my desk: 3gig (from August 1997), 8gig (March 1999), 13gig (March 2000), and 80gig (June 2004). Yes, WD stamps the date on their drives...and they all work as flawlessly as the day they were purchased. It's just difficult to justify using 5volts to gain so little space.
