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.
Product Features
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 By using environmentally-conscious PCs with our
WD Caviar Green drives on board, large organizations with many desktop computers can
minimize their carbon footprint and save real money on electricity costs.
Cool and quiet GreenPower™ technology yields lower operating temperatures for
increased reliability and low acoustics for ultra-quiet PCs and external drives.
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.
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.
IntelliSeek™ Calculates optimum seek speeds to lower power consumption, noise, and
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.
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 model only)
Native Command Queuing (NCQ) — Server feature for performance in random I/O
transaction environments. It aggregates many small random data transfers and allows the disk
to reorder the commands in a sequential order for faster access.
Perpendicular Magnetic Recording (PMR) — Employs PMR technology to achieve even
greater areal density.
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.
WD Caviar Green is part of WD's complete lineup of desktop hard drives.
