0B48716 WD Ultrastar DC HC555 14TB SATA 512 MB 3.5" Server HDD

High-Capacity 3.5in Datacenter SATA HDD featuring helium EAMR/TDMR recording with the 0B48716

The 0B48716 is a WD Ultrastar DC HC555 internal datacenter HDD engineered for capacity-led architectures where predictable throughput, consistent latency, and operational efficiency matter more than peak IOPS. As a 3.5in 14TB SATA drive, it aligns with mainstream server and storage backplanes while supporting 24x7 duty cycles in dense RAID/JBOD shelves and hybrid arrays.

Architecturally, the 0B48716 combines helium-filled mechanics with EAMR and TDMR recording to sustain higher areal density while maintaining signal integrity at scale. The 7200RPM design and 512MB cache balance sequential performance for object and file stores, backup tiers, and cold/warm data lakes. For data governance, the 0B48716 integrates Self-Encrypting Drive capabilities with TCG Enterprise SSC, enabling hardware-based encryption without shifting overhead to the host CPU. With 4Kn/512e sector support, the 0B48716 fits modern filesystem and array layouts, reducing migration friction when standardizing large-capacity pools.

Why Choose the 0B48716?

The 0B48716 delivers a high density-to-power profile for scale-out storage nodes and capacity tiers, helping IT teams increase usable TB per rack unit while staying within power and thermal envelopes. With enterprise endurance characteristics and a 2.5M-hour MTBF class, the 0B48716 supports predictable fleet behavior in multi-drive enclosures and simplifies lifecycle planning for backup repositories and archival platforms.

WD designs Ultrastar platforms with datacenter reliability targets, controlled acoustics and vibration tolerance, and compatibility with modern RAID/JBOD standards. This engineering focus supports consistent operation under continuous workloads and integration into standardized provisioning and security policies.
