0B47061 WD Ultrastar DC HA340 12TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5-inch Enterprise SATA HDD for nearline storage tiers with the 0B47061

The 0B47061 is a WD Ultrastar DC HA340 12TB internal 3.5-inch enterprise HDD engineered for sustained throughput and predictable latency in always-on server and storage architectures. Positioned for nearline tiers rather than compute acceleration, the 0B47061 integrates cleanly into modern CPU platforms by offloading bulk data retention from expensive flash while preserving consistent performance under mixed sequential and background maintenance activity.

Built on CMR recording with a 7200RPM spindle and 512MB cache, the 0B47061 supports stable write behavior that aligns with RAID rebuild windows and data protection policies in dense storage nodes. The SATA interface enables broad compatibility across PCIe-attached HBAs, SAS expanders via interposers, and legacy backplanes, while 512e sector emulation supports migration paths from 512-byte stacks and simplifies OS and hypervisor integration. For data center operations, features such as Secure Erase and Power Disable assist with fleet lifecycle control and remote serviceability in high-density chassis.

Why Choose the 0B47061?

The 0B47061 delivers a pragmatic density-to-cost profile for capacity expansion without re-architecting storage connectivity, making it suitable for scale-out NAS/SAN shelves and server-based storage. With enterprise 24/7 duty design and a 2.0M hour MTBF rating, the 0B47061 supports predictable deployment planning, spares strategy, and operational continuity across large drive populations.

WD designs Ultrastar platforms with data center validation, vibration-aware mechanics, and firmware behaviors tuned for multi-drive environments. The 0B47061 aligns with standard 3.5-inch service models and common rack storage conventions, supporting consistent qualification processes and straightforward fleet standardization.

Key Applications:

• Backup repositories
• Archive and compliance retention
• Bulk object and file storage pools
• Capacity expansion in storage arrays
• Nearline tiers for virtualized environments
