WD 10TB Ultrastar DC HC330 7200 rpm SATA III 3.5″ Internal Data Center HDD

 Western Digital 10TB Ultrastar DC HC330 7200 rpm SATA III 3.5″ Internal Data Center HDD – 0B42266 (also known by its full model number WUS721010ALE6L4) is a robust, enterprise-class hard disk drive designed for the demanding requirements of 24/7 continuous operation in data centers, servers, and high-capacity storage systems. It represents a cost-effective solution for traditional IT workloads that require a strong balance of capacity, performance, and reliability.

Key Features

• Capacity: A significant 10TB, offering ample storage for large datasets and enterprise applications.
• 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 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: 256MB, which helps optimize data flow, reduce latency, and improve overall drive responsiveness under heavy loads.
• Max, Sustained Transfer Rate: Up to 273 MB/s, indicating strong sequential read/write capabilities vital for large file transfers and and continuous data streams.
• Workload Rating: An impressive 550TB per year.

Specifications

Reliability:

• • MTBF (Mean Time Between Failures): Up to 2.0 million hours. This exceptional rating is a hallmark of enterprise drives, emphasizing its suitability for continuous, mission-critical operations where downtime is unacceptable.
  • Annualized Failure Rate (AFR): 0.44% (Some sources state 0.35%, but 0.44% is more commonly cited for this series).
  • Non-recoverable Read Errors: Less than 1 per 1015 bits read, ensuring very high data integrity.
• Recording Technology: Employs CMR (Conventional Magnetic Recording)
• Vibration Protection (Enhanced RVS – Rotational Vibration Safeguard): Incorporates sophisticated electronics that actively detect and compensate for both linear and rotational vibrations in real-time. This is crucial for maintaining consistent performance and reliability in dense, multi-drive server racks where vibrations can degrade performance.
• TLER (Time-Limited Error Recovery): Essential for RAID configurations.
• Sector Format: Primarily 512e (512-byte emulation), offering broad compatibility with modern operating systems and hardware while leveraging larger physical sectors.
• Self-Encrypting Drive (SED) Options: The 0B42266 model typically includes Secure Erase (SE) technology, which provides a fast and effective way to securely wipe data from the drive, and in some contexts, implies a Self-Encrypting Drive (SED) capability for hardware-based encryption.
• Dual-Stage Micro Actuator Technology: Enhances head positioning accuracy for better drive performance.
• Non-Volatile Cache (NVC) / Media Cache Plus: Helps improve write performance and data integrity, particularly during unexpected power loss, by utilizing a flash-backed DRAM cache in addition to a disk-based cache.
• 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.

Ideal Use Cases

• Enterprise Servers: Providing reliable storage for mission-critical applications that require 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 where cost-effectiveness and reliability are key.
• Enterprise Storage Systems: Such as traditional RAID arrays, rack-mounted storage enclosures, and server-based distributed storage systems.
• Big Data Analytics Platforms: For scenarios 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.
