Technology Features

IntelliSeek –Optimizes seek speeds to lower power

consumption, noise, and vibration.

Perpendicular Magnetic Recording (PMR) –WD RE2 drives

employ PMR technology to achieve even greater areal density.

Preemptive Wear Leveling (PWL) –The drive arm frequently

sweeps across the disk to reduce uneven wear on the drive

surface.

Rotary Acceleration Feed Forward (RAFF™)– Provides

best-in-class vibration tolerance by optimizing operation and

performance when the drives are used in vibration-prone,

multi-drive systems such as rack-mounted servers or network

storage.

SecurePark – The recording heads are parked off the disk

surface during spin up, spin down, and when the drive is off.

This ensures the recording head never touches the disk surface

resulting in improved long-term reliability due to less head wear

and improved non-operational shock tolerance.

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.
