3TB Western Digital Caviar Green 64MB Cache IntelliPower (WD30EZRX)

Reduced power consumption.
Reduced power consumption makes it possible 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 perfect for ultra-quiet PCs and external drives.

The world's largest capacity internal hard drive.
WD Caviar Green SATA drives now deliver up to a massive 3 TB's of storage on a single drive.

WD meets the technological challenges of implementing 3 TB SATA hard drives.
SATA hard drives are now capable of storing up to 3 TB of data on a single hard drive. WD is leading the way in the industry, providing you with solutions for implementing 2.19 TB and larger drives.

Perfect for external drives.
External drive manufacturers can eliminate the need for a fan in a high-capacity product by utilizing the cool and quiet operation of WD Caviar Green hard drives.

IntelliSeek.
Calculates optimum seek speeds to lower power consumption, noise and vibration.

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.

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.

Advanced Format (AF).
Technology being adopted by WD and other drive manufacturers as one of multiple ways to continue growing hard drive capacities. AF is a more efficient media format that enables increased areal densities. (RX, RS and RSDTL models only)

Ideal for:
PCs, external storage and other devices that require lower power consumption and cool, quiet operation.

Desktop / Consumer RAID Environments - WD Caviar Green Hard Drives are tested and recommended for use in consumer-type RAID applications. (RAID-0 / RAID-1)*

Large Capacity Drives

Meeting the technological challenges of 3 TB SATA hard drive implementation.

Once again leading the way in the storage industry, WD now offers 2.5 TB and 3 TB hard drives, the world's largest capacities to date on a single drive. At such high capacities certain compatibility issues arise. There are a number of host bus adapter (HBA) and chipset vendors not currently offering drivers that support drives larger than 2.19 TB. To provide a solution for these types of compatibility issues, WD is bundling WD Caviar® Green™ 2.5 TB and 3 TB drives with an ACHI-compliant HBA that, once installed, allows the operating system to use a known driver to correctly support large capacity drives.

To understand if your system will support a hard drive with greater than 2.19 TB, consult your OS, Motherboard and USB bridge device solution providers from the list below before you attempt to install in your system.

• As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, megabit per second (Mb/s) = one million bits per second, and gigabit per second (Gb/s) = one billion bits per second.
