Key Features

• Capacity: A solid 6TB of storage, suitable for various enterprise applications requiring a balance of capacity and cost.
• Form Factor: Standard 3.5-inch, ensuring broad compatibility with server bays and storage arrays.
• Interface: SATA III (6 Gb/s), providing a fast and widely compatible connection for efficient data transfer.
• Rotational Speed (RPM): 7200 RPM, delivering robust performance for a mechanical drive, essential for responsive data access in multi-user environments.
• Cache Size: Typically 256MB, which helps optimize data flow and improve drive responsiveness under heavy loads. Some older or specific sub-variants might have 128MB, but 256MB is common for this part number.
• Max. Sustained Transfer Rate: Up to 255 MB/s, indicating strong sequential read/write capabilities for large file transfers.
• Workload Rating: An impressive 550TB per year. This is a critical enterprise-grade metric, highlighting its ability to handle extremely high volumes of data read/write cycles annually, significantly exceeding consumer-grade drives (which are typically rated for 55TB/year).

Specifications

Reliability:

• • MTBF (Mean Time Between Failures): Up to 2.0 million hours (some sources indicate up to 2.5 million hours for the series), a hallmark of enterprise drives designed for continuous, mission-critical operations where minimizing downtime is paramount.
  • Load/Unload Cycles: 600,000 cycles, showcasing its mechanical durability.
  • Non-recoverable Read Errors: Less than 1 per 1015 bits read, ensuring very high data integrity.
• Vibration Protection (Enhanced RVS – Rotational Vibration Safeguard): Features sophisticated electronics that actively detect and compensate for both linear and rotational vibrations in real-time. This is vital for maintaining consistent performance and reliability in dense, multi-drive server racks where vibrations can degrade performance.
• Sector Format: Primarily offered in 512e (512-byte emulation), which provides broad compatibility with modern operating systems and hardware while leveraging larger physical sectors. Some lower-capacity models in this series might also have 512n (native) options for legacy system compatibility.
• Dynamic Fly Height Technology: Adjusts each read-write head’s fly height in real time for optimal reliability and read/write performance across the platters.
• Dual-Stage Actuator Technology: Provides a high degree of head positioning accuracy. The primary stage offers coarse displacement, while the secondary stage uses piezoelectric motion for fine-tuning.
• Compatibility: Extensively tested and validated for broad compatibility with various OEM storage systems, SATA controllers, and host bus adapters, ensuring seamless integration into complex IT infrastructures.
• Warranty: Backed by a robust 5-year limited warranty, reflecting its enterprise-grade design and intended long-term, continuous operation.
• Power Consumption (Typical): Operational: ~7.0W; Idle: ~5.9W. Being an air-filled drive (not HelioSeal), its power consumption is optimized for its design class.

Ideal Use Cases

The WD Ultrastar DC HC310 6TB (0B36039) is purpose-built for:
