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.
