Product description Hard Drives by Application: Which Is Best for You? Read More Designed with SMB customers in mind, the 4TB Red Pro 7200 rpm SATA III 3.5" Internal NAS HDD from WD is well-suited for medium to large-scale NAS environments with up to sixteen 3.5" drive bays. Engineered to handle increased workloads, this 4TB drive operates using a SATA III 6 Gb/s interface, a 256MB cache, and a rotational speed of 7200 rpm, which all help to ensure uninterrupted data transfers with a sustained rate of up to 217 MB/s. This drive also features high levels of reliability, with 600,000 load/unload cycles, <10 in 1015 non-recoverable read errors per bits read, dual-plane balance control technology, and 1,000,000 hours MTBF for 8-16 bay NAS systems. Shock protection is provided by a multi-axis shock sensor and WD's NASware 3.0 helps increase system compatibility, allowing Red Pro drives to be more easily integrated with your existing network infrastructure. 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).
