0B47078

Enterprise 3.5in Nearline SATA HDD Architecture for Bulk Storage with the 0B47078

The 0B47078 is a WD Ultrastar DC HA340 enterprise hard drive engineered for high-density nearline storage in rack servers and JBOD enclosures where capacity and predictable latency matter more than NVMe-class IOPS. As a single 3.5in internal 8TB SATA HDD, it supports sustained throughput for sequential and mixed read/write patterns common in backup targets, content repositories, and general-purpose server storage pools.

Built on a 7200RPM CMR recording design with Advanced Format 512e, the 0B47078 aligns cleanly with modern OS and RAID/HBA stacks while maintaining consistent write behavior under steady-state workloads. The SATA interface simplifies integration across existing storage backplanes, and the 256MB cache helps absorb burst writes and optimize command queuing. For operational resilience, the 0B47078 is specified for 24x7 duty cycles with rotational vibration safeguards and a dual-stage actuator to reduce track misregistration in multi-drive chassis.

Why Choose the 0B47078?

The 0B47078 delivers a practical density-to-performance profile for enterprises standardizing on large SATA HDD pools, enabling cost-efficient scaling in RAID arrays, erasure-coded clusters, or JBOD-based object storage. Its nearline architecture supports predictable fleet behavior, while reliability engineering helps maintain service levels in high-bay, vibration-prone server environments.

WD’s Ultrastar engineering focuses on sustained datacenter operation, consistent firmware behavior, and compatibility with common storage controllers and enclosure designs. The platform is built to meet modern operational expectations for uptime, maintenance windows, and large-scale drive population management.

Key Applications:

Bulk nearline storage for servers and JBOD
Backup and restore repositories
Cold-to-warm data tiers
General-purpose SATA HDD pools

At Happyware - Server Hardware you benefit from non-binding offers tailored precisely to your rollout and capacity targets, helping you standardize the 0B47078 across projects with clear procurement planning. For additional investment security in long-lived storage platforms, you can extend the warranty up to 6 years.
