Product Description

Available in capacities up to 2 TB, WD Caviar Green SATA hard drives reduce power consumption by up to 40 percentage 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.

Features at a glance Reduced power consumption Environmentally responsible Cool and quiet 3-year limited warranty

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.

Customer Reviews

May be the "green" drive to get right now
If you're looking for a low power drive, the Western Digital WD10EADS is one of the best options currently. It has by far the lowest idle and active power consumption statistics. That, not surprisingly, helps it run cooler than other drives as well.

There is some performance loss, though most users will probably not notice. For detailed stats, look up the Winter 2008 Hard Drive Guide at Tom's Hardware. (Though you may notice how quiet and cool it is!)

Also, note that this is the OEM or Bulk version of the drive, with no SATA data cable or power adapter, or screws if your system uses them.

Eco-Friendly Option for Computer AND external drives!
WD engineering continues to impress me and I've been in the IT business for 20+ years as an engineer on all levels. When used in an Apple computer these drives impress with the hardware and OS ability to control the drive for increased performance. Some PC's are being built with this capability as well, but even without it the on-board processor performs fantastic. I would however not recommend this drive in a server due to it's variable spindle speed.

In an external enclosure SATA II through Firewire 800 sustained speeds matched a WD Black 1tb drive, basically maxing out the FW800 bandwidth. Through USB 2.0 they both performed identical as well but USB speeds are based on the external enclosures chip and since it's Serial (USB) it's ONE WAY at a time which makes it slow when compared to FW400/800.

Temps in an iMac were less than 109* at most times, rarely exceeding 110* which also resulted in lower fan noise.

Lower Heat, Less power generally equal longer life and higher reliability however these drives are still new. But as of this review our company has 2 in a NAS Enclosure running in RAID1 for the last 4 months non-stop without any issues.

The WD Black drives would be ideal when performance is what matters but in situations where energy consumption and more importantly heat is considered the ideal attribute these drives are best. The WD black is about 30% faster overall on either Mac/Pc.

Spindle speed varies from 4200rpm-7200rpm on newer models, first generation varied 5400rpm-7200rpm. Both are able to stop altogether through a spin down feature however this will never "spin-down" on a windows based machine due to the indexing Windows employs that access's the drive once every 3 seconds.

Why you need this drive
For those that don't know why you want a low-power drive:
It's not just for the environment or your electricity bill--those are just added bonuses. A hard drive can generate a lot of heat inside of your system. This means that (a) your fans will have to blow faster (and thus your computer gets significantly louder), but also that the rest of your computer (CPU, graphics card, etc) are operating at a higher heat. This means that they are running at a lower efficiency rate, as well as with an increased risk of failure. Long story short, your computer will run quieter, faster, and more efficiently, and will also last longer with fewer failures.

This particular drive runs faster than a lot of low-power drives, and has been incredibly reliable. It's 7200 rpm and 32mb cache are rather good specs, especially compared to other drives out there--make sure you check those two specs before you buy! The price also cannot be beat.

It unfortunately doesn't come with any cables, so I would strongly suggest getting this (as I did): Cables Unlimited Serial ATA Cable Kit. It comes with both the sata connector for your motherboard as well as a power adapter to power your drive from a 4-pin molex cable from your power supply.
