General Features
Professional Solutions
Designed specifically with SMB customers in mind the WD Red family has expanded with the addition of WD Red Pro, which is available for the 8 to 16 bay medium to large-scale NAS environments. With a 4TB storage capacity, this WD Red Pro drive carries a 5-year limited warranty and was engineered to handle the increased workloads from your business.
NASware 3.0 Technology
With advanced firmware technology built into this WD Red Pro drive, NASware 3.0 enables seamless integration, robust data protection and optimal performance for systems operating in the demanding NAS environment.
Vibration Protection
In combination with 3D Active Balance Plus, WD Red Pro also features hardware vibration compensation technology which monitors the drive to correct both linear and rotational vibration in real time, further increasing drive reliability.
Enhanced Accuracy for NAS
For overall enhanced accuracy for NAS, WD Red Pro is also equipped with dual actuator technology which improves positional accuracy over the data tracks and head positioning. StableTrac technology then secures the motor shaft at both ends to reduce system-induced vibration and stabilize the drive platters for accurate tracking during read and write operations. Both technologies are important for larger 8 to 16 bay NAS environments.
8 to 16 Bay Shock Protection
WD Red Pro is equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read-write function to compensate and protect the data. This combination of technology further protects the drives in large 8 to 16 bay NAS environments and increases drive reliability.
Error Recovery Prevention
Built specifically for RAID and NAS environments, WD Red Pro drives come equipped with error recovery controls as part of NASware 3.0, which prevents the drive from fallout in RAID applications.
Longer Warranty Coverage
Complimenting WD Red at a 3-year limited warranty, WD Red Pro offers longer warranty coverage with a 5-year limited warranty for an even greater peace of mind.
Premium Support
Every WD Red Pro hard drive comes with support services including a premium dedicated 24/7 support line (available in English, other regional support hours vary).

Please note support outside of normal business hours is available in English only
