WD Gold Enterprise-Class SATA HDD – 2TB (WD2005FBYZ)

The Western Digital Gold Enterprise Class SATA HDD – 2TB – WD2005FBYZ is a specialized 3.5-inch internal hard disk drive designed for demanding datacenter and enterprise applications.

Key Features & Specifications

• Capacity: 2TB, providing solid storage for various server-side applications.
• Form Factor: 3.5-inch, standard for server and workstation internal drives.
• Interface: SATA III (6 Gb/s), offering a fast connection for data transfer.
• Rotational Speed (RPM): 7200 RPM, delivering good performance for a mechanical drive, essential for responsiveness in server environments.
• Cache Size: 128MB.
• Sustained Transfer Rate: Up to 200 MB/s
• Workload Rating: Up to 550TB per year. This is a crucial indicator of its endurance, meaning it’s designed to handle a massive amount of data read/write cycles annually, far exceeding typical desktop drives (which might be around 55TB/year).
• Reliability:
  • MTBF (Mean Time Between Failures): Up to 2.0 million hours. This is an exceptionally high rating, emphasizing its suitability for continuous, mission-critical operations where downtime is unacceptable.
  • Load/Unload Cycles: 600,000 cycles.
  • Non-recoverable Read Errors: Less than 1 in 1015 bits read, indicating very high data integrity.
• Vibration Protection: Features sophisticated electronics and technologies (like Enhanced RAFF™ Technology) to monitor and correct both linear and rotational vibrations in real time. This is vital for maintaining performance and reliability in multi-drive server racks where vibrations can be a significant issue.
• “RAID-specific, Time-Limited Error Recovery (TLER): This crucial feature helps prevent drives from dropping out of RAID arrays. Dynamic Fly Height Technology: Adjusts each read-write head’s fly height in real time for optimal reliability.
• Dual Actuator Technology:  This technology found in some Gold drives improves positional accuracy over data tracks.
• Compatibility: Extensively tested across various OEM storage systems, SATA controllers, and host bus adapters for seamless integration.
• Warranty: Backed by a 5-year limited warranty, reflecting its robust design and intended long-term use in demanding environments.
• Power Consumption: (Typical values) Read/Write: 7.4W, Idle: 5.9W.
• Acoustics (dBA): Idle: 25 dBA, Seek (average): 28 dBA.

Ideal Use Cases

• Enterprise servers: For applications requiring high uptime and consistent performance.
• Datacenter environments: This category notably includes hyperscale deployments, as well as private cloud storage, and also extends to data warehousing.
• Enterprise storage systems: Such as large RAID arrays and SAN/NAS solutions.
• Data warehousing/mining: Where large datasets are constantly accessed and processed.
• High-end surveillance systems: That require robust, reliable storage for continuous recording.
