Enterprise Hard Drives

WD RE3 SATA Hard Drives
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.
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 (GB) = 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 (MB/s) = one million bytes per
second, and gigabit per second (Gb/s) = one billion bits per second. 2178-701099-A01 Ltr Aug 2008
