General Description
WD Green hard drives are designed for use in systems that require cool and quiet operation, as
secondary drives in PCs, for external enclosures and other applications for which low noise and low
heat are beneficial. These earth-friendly drives are ideal for use whenever energy efficiency is needed.

Product Features
15 mm Height
- 1.5 TB and 2 TB models are 15.0 mm high and are not compatible with
notebook systems. Targeted application is external hard drives.
Serial ATA (SATA) —
Serial ATA (SATA) is the next generation bus interface for
2.5-inch hard drives. It is designed to replace Parallel ATA, and has many advantages including
increased transfer rate, improved signal integrity, enhanced data protection, and hot plug support.
Advanced Format (AF)
— Technology adopted by WD and other drive manufacturers to
increase media format efficiencies, thus enabling larger drive capacities.
IntelliPower™
— A fine-tuned balance of spin speed, transfer rate and caching algorithms
designed to deliver both significant power savings and solid performance. For each WD Green
drive model, WD may use a different, invariable RPM.
Fluid Dynamic Bearings (FDB)
— A bearing design that allows ultra-low rotational drag while
providing high lateral stiffness to steadily hold the spinning center of the diskpack for
high-accuracy of reading and writing of data. FDB provide increased shock robustness and
enhanced reliability while reducing power consumption and acoustics.
Perpendicular Magnetic Recording (PMR) —
With PMR technology the magnetization of each
data bit is aligned vertically to the spinning disk, rather than longitudinally as has been the case in
hard drive technology for decades. This enables more data on a given disk than is possible with
conventional longitudinal recording, and provides a platform for future expansion of hard drive
densities.
Reduced Power Spinup (RPS)
— WD’s optimized start up feature specifically designed for the
external hard drive and Consumer Electronics (CE) market. Specific focus for RPS is to minimize
the duration and magnitude of the peak power consumption from the hard drive.
System-on-Chip
- The System-on-Chip (SOC) is the foundation for WD's next generation
electronics and firmware architecture. The native SATA SOC lowers component count by
integrating a hard disk controller, high performance processor, high speed execution SRAM, and
read channel in a 128-pin package.
S.M.A.R.T. Command Transport (SCT)
— The SCT Command Transport feature set provides
a method for a host to send commands and data to a device and for a device to send data and status
to a host using log pages.
Reliability Features Set-Data Lifeguard™
— Representing WD's ongoing commitment to data
protection, Data Lifeguard includes features that enhance the drive’s ability to prevent data loss.
Data Lifeguard data protection utilities include thermal management, an environmental
protection system, and embedded error detection and repair features that automatically detect,
isolate, and repair problem areas that may develop over the extended use of the hard drive. With
these enhanced data reliability features, the drive can perform more accurate monitoring, error
repair, and deliver exceptional data security.
Hot Plug Support
— SATA supports hot plugging (also known as “hot swapping”), the ability to
swap out a failed hard drive without having to power down the system or reboot. This capability
contributes to both data availability and serviceability without any associated downtime, making it
a critical feature for extending SATA into enterprise applications.
