Western Digital Ultrastar DC SATA HDD – 7200 RPM Class, SATA 6 Gb/s, 3.5″ 6TB 0B36039

Western Digital Ultrastar DC SATA HDD – 7200 RPM Class, SATA 6 Gb/s, 3.5″ 6TB 0B36039 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: Enterprise Servers: For mission-critical applications requiring high uptime, consistent performance, and robust data integrity in a 24/7 operational environment. Datacenter Environments: Including mid-capacity tiers of cloud storage, private cloud infrastructure, and data warehousing. Enterprise Storage Systems: Such as traditional RAID arrays, rack-mounted storage enclosures, and server-based distributed storage systems. Big Data Analytics Platforms: Where continuous access to and processing of large datasets are required. High-End, Continuous Video Surveillance Systems: That demand reliable and performant storage for long-term continuous recording and archiving of large volumes of video data.
