WD Gold Enterprise Class SATA HDD – 16TB – WD161KRYZ

• WD Gold Enterprise-Class SATA HDD – 16TB (WD161KRYZ)

The Western Digital Gold Enterprise Class SATA HDD – 16TB – WD161KRYZ is a premier 3.5-inch internal hard disk drive, meticulously engineered for the most rigorous 24/7 enterprise and datacenter environments. It delivers a massive 16TB of storage capacity, coupled with advanced features that prioritize extreme reliability, robust performance, and unwavering data integrity under heavy, continuous workloads.

Key Features

• Capacity: A substantial 16TB, providing immense storage for large datasets, extensive archives, and demanding applications in enterprise settings.
• Form Factor: Standard 3.5-inch, ensuring broad compatibility with server bays, storage arrays, and enterprise-grade workstations.
• Interface: SATA III (6 Gb/s), offering a high-speed and widely compatible connection for efficient data transfer.
• Rotational Speed (RPM): 7200 RPM, delivering robust performance for a mechanical drive, crucial for responsiveness and throughput in multi-user and data-intensive scenarios.
• Cache Size: A generous 512MB, optimizing data flow, reducing latency, and enhancing overall drive responsiveness, especially under heavy loads.
• Max. Sustained Transfer Rate: Up to 262 MB/s (Host to/from drive sustained), indicating strong sequential read/write capabilities vital for large file transfers and continuous data streams.
• Workload Rating: An industry-leading 550TB per year. This metric is a key differentiator for enterprise drives, signifying its ability to handle an extremely high volume of data read/write cycles annually – far exceeding the endurance of consumer-grade drives.
• Reliability:
  • MTBF (Mean Time Between Failures): Up to 2.5 million hours. This exceptional rating underscores its suitability 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 extremely high data integrity for sensitive business information.

SPECIFICATION

• HelioSeal™ Technology: As a high-capacity drive (12TB and above in the Gold series), it utilizes helium-filled technology. This allows for thinner platters and reduced internal friction, leading to higher capacity, lower power consumption, and improved reliability.
• Vibration Protection (Enhanced RVS – Rotational Vibration Safeguard): Incorporates sophisticated monitoring electronics and dual sensors that actively detect and correct 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 and lead to errors.
• RAID-specific, Time-Limited Error Recovery (TLER): This feature is essential for RAID (Redundant Array of Independent Disks) environments. It prevents drives from being prematurely dropped from arrays due to extended error recovery processes, thus preserving array stability and data availability.
• 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.
• Energy-Assisted Magnetic Recording (EAMR) and Triple Stage Actuator (TSA): For capacities 16TB and above (including this model), these technologies enable higher areal density and enhance head-positioning accuracy, contributing to better performance and data integrity.
• 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 in demanding environments.
• Power Consumption (Typical): Operational: ~6.5W; Idle: ~5.6W. The HelioSeal technology contributes to its relatively lower power draw for its capacity.
• Acoustics (Average): Idle Mode: 20 dBA; Seek Mode: 36 dBA.
• Formatted Capacity: 512e (512-byte emulation) user sectors, providing broad compatibility with legacy and modern systems.

Ideal Use Cases

• Enterprise Servers: Ideal for applications requiring high uptime, consistent performance, and robust data integrity in a 24/7 operational environment.
• Datacenter Environments: Including hyperscale cloud storage, private cloud infrastructure, and data warehousing where extreme reliability and endurance are paramount.
• Enterprise Storage Systems: Such as large RAID arrays, high-bay Network Attached Storage (NAS) systems, and Storage Area Networks (SANs).
• Big Data Analytics and Mining: For scenarios where massive datasets are constantly accessed, processed, and written.
• High-End, Continuous Video Surveillance Systems: That require highly reliable and performant storage for long-term continuous recording and archiving of large volumes of video data.
• Hybrid Cloud and Colocation Storage: For businesses needing scalable local or distributed storage solutions with enterprise-level dependability.
