Synopsis
WD Advanced Format technology increases media format efficiency, thus enabling larger drive capacities. WD Advanced Format drives are specifically optimized for Mac and the latest Windows operating systems such as Windows Vista and Windows 7. WD Advanced Format drives work with legacy operating systems such as Windows XP but require the use of the free WD Align software available on www.wdc.com/advformat.Available in capacities up to 2 TB, WD Caviar Green SATA hard drives reduce power consumption by up to 40% and offer best-in-class acoustics and operating temperature. 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. 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. They are ideal for PCs, external storage and other devices that require lower power consumption and cool, quiet operation.

I have bought a LOT of the 2TB WD Caviar drives. I have had excellent results with them on my iMac. I use them primarily for data storage where fast data retrieval is not a consideration. I'm more concerned with plugging them into these USB-based drive docks when I need the data. However, I'm also interested in them from an electrical perspective, just because ... well, just because I'm interested in them. Over the years I have worked my way up the ladder of hard drive storage capacities. Like many of you, I've been rather appalled at how hot these older models would get. I swear, you could fry an egg on some of them. I never felt comfortable with their longevity, fearing that they would most likely burn themselves up. Fortunately, none did.
When the Caviar Green product line came out (1TB was when I first took notice), I was quite intrigued at the claimed power reduction. In electronics, heat is the main enemy of components. Usually every 10 degree C rise in temperature...

I purchased these drives to create a RAID 5 setup for home storage, turns out these drives have terrible characteristics for RAID because of the "Green" firmware. If you are using these drives as stand-alone drives everything should be fine, if you are looking to put together a RAID (software or hardware) look somewhere else, there are plenty of consumer-grade drives that work well with RAID.

I've bought six of these. They are quiet. After many hours, they are barely warm to the touch. Every other hard-disk drive made can be used as a space heater.
They are a bit slower, adding about 33% to the seek time, but nothing noticeable to data reads. This only matters when reading lots of small files like during boot-up. I use an Intel SSD for my main drive and one of these for data. It is the best of both worlds.
I've found that most computers recognize these drives but must be told to mount them, format them, and assign them a drive letter. (This only needs to be done once.) This is a problem with large drives, not with these specifically. For true ease of setup, get a 1TB drive.
