Key Features Key Specifications

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. (750 GB and above)

RAFF — Our fourth generation RAFF technology includes

•

sophisticated electronics to monitor the drive and correct both
linear and rotational vibration simultaneously in real time for up to
a 60% performance improvement over the previous generation of
drives operating in high vibration environments.

IntelliSeek™ — Calculates optimum seek speeds to lower power

•

consumption, noise, and vibration in active seek modes without
degrading performance.

Multi-axis shock sensor — An additional third sensor has been

•

added to automatically detect subtle high frequency shock events
in all axis enabling compensation to protect the data.

Enterprise Hard Drives

RAID-specific, time-limited error recovery (TLER) — Prevents

•

drive fallout caused by the extended hard drive error-recovery
processes common to desktop drives.

Third generation dynamic fly height — Each read-write head’s

•

fly height is adjusted in real time for optimum reliability.

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) — WD RE3 drives

•

utilize PMR technology to achieve even greater areal density,
reliability, and design margin.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (G B) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total
accessible capacity varies depending on operating environment. As used for transfer rate or interface, megabyte per second (M B/s) = one million bytes per
second, and gigabit per second (Gb/s) = one billion bits per second. 2178-70109 9-A01 Ltr Aug 2008
