0B47063 WD Ultrastar DC HA340 12TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5in Enterprise SATA HDD for Datacenter Arrays with the 0B47063

The 0B47063 is a 12TB WD Ultrastar DC HA340 3.5in internal HDD designed for capacity-tier server storage where predictable throughput, sustained write behavior, and 24/7 duty cycles are mandatory. In RAID arrays and SDS nodes, the 0B47063 supports consistent rebuild and scrub operations by using CMR recording at 7200 RPM with a 512MB cache, helping maintain steady latency under mixed sequential and random access patterns.

Built around a SATA interface with 512e sector formatting, the 0B47063 integrates cleanly into widely deployed enterprise backplanes and HBA configurations while maintaining alignment for modern filesystems and storage stacks. As a self-encrypting drive, the 0B47063 provides hardware-based encryption suitable for controlled decommissioning workflows and compliance-driven data handling. For capacity expansion, the 0B47063 is optimized for dense shelves and general-purpose capacity tiers, supporting backup repositories, log retention, and media repositories without forcing changes to host PCIe topology or controller strategy.

Why Choose the 0B47063?

The 0B47063 delivers a balanced density-to-performance profile for organizations scaling bulk storage while protecting service continuity. With enterprise-class reliability and a 2.0M-hour MTBF, the 0B47063 is engineered for long-lived deployments where predictable operations, fleet consistency, and straightforward lifecycle management are priorities across multi-node storage estates.
