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.
