0B47062 WD Ultrastar DC HA340 10TB SATA 512 MB 3.5" Server HDD

Enterprise 3.5in Datacenter SATA HDD engineered for predictable nearline storage with the 0B47062

The 0B47062 is a WD Ultrastar DC HA340 10TB 3.5in internal datacenter HDD designed for server storage bays and dense RAID shelves where consistent latency matters more than peak IOPS. Built around CMR recording and a 512e sector format, the 0B47062 supports predictable write behavior under sustained workloads, reducing rebuild risk and performance variance in multi-drive arrays.

With a 7200RPM spindle and 512MB cache, the 0B47062 is tuned for bulk data services such as backup targets, object-like repositories, and nearline tiers that prioritize capacity efficiency. The SATA interface aligns with widely deployed backplanes and HBAs, enabling straightforward expansion in scale-out storage nodes while maintaining serviceability. For security-sensitive environments, the 0B47062 includes self-encrypting drive capability to support data-at-rest protection policies without redesigning the storage architecture.

Why Choose the 0B47062?

The 0B47062 delivers a pragmatic density-to-cost profile for 24/7 duty-cycle pools, pairing CMR consistency with enterprise reliability characteristics suitable for large RAID groups. In designs where operational continuity is the priority, the 0B47062 supports predictable fleet behavior, simplified capacity scaling, and standardized spare strategy across homogeneous nearline tiers.

WD engineers the Ultrastar portfolio for continuous operation in modern data centres, emphasizing controlled acoustics, power-aware operation, and validation for multi-drive enclosures. The 0B47062 aligns with enterprise lifecycle planning through reliability expectations such as 2.0M hours MTBF and integration patterns common to rack servers and storage appliances.

Key Applications:

• RAID arrays in rack servers
• Backup and restore repositories
• Nearline bulk storage tiers
• Archival and compliance retention
• Capacity expansion for storage appliances
