Description

Optimized for NAS with NASware Western Digital’s exclusive NASware technology fine tunes drive parameters to match NAS system workloads, which helps increase performance and reliability

Designed for Continuous Operation WD Red Pro hard drives are designed to handle the rigorous demands of high-intensity 24x7 multi-user NAS environments and increase system durability

Tested for Dependable Compatibility Western Digital partners with a wide range of NAS system vendors for extensive testing to ensure compatibility with most NAS enclosures

Protected against Excessive Vibration WD Red Pro drives include Rotation Vibration (RV) sensors that anticipate and proactively counteract disturbances caused by increased vibration

By dispersing excess vibration across the drive chassis, turbulence is minimized, performance is maintained and drives are protected

Built to Absorb Shock WD Red Pro hard drives include a multi-axis shock sensor to detect subtle shock events and automatically compensate with dynamic fly height technology to further protect the drives in NAS enclosures
