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.
