Reliable and rugged
-WD's ShockGuard™ technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation.
-WD's SecurePark parks the recording heads 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 shock tolerance.
