0B48714 WD Ultrastar DC HC555 20TB SAS 512 MB 3.5" Server HDD

High-Capacity 3.5in SAS Datacenter HDD for bulk storage tiers with the 0B48714

The 0B48714 is a 20TB WD Ultrastar DC HC555 internal 3.5in SAS HDD engineered for capacity-dense storage nodes where throughput consistency, predictable latency, and 24x7 duty cycles are mandatory. In SAS JBOD and RAID topologies, the 0B48714 supports resilient scale-out designs by keeping large datasets close to compute while maintaining serviceability in standard hot-swap bays.

Built on helium-filled mechanics with TDMR and EAMR recording technologies, the 0B48714 targets higher areal density without compromising sustained operation in multi-drive enclosures. The 4Kn sector format with 512e emulation aligns with modern OS and storage stack requirements, while the 512MB cache helps absorb bursty I/O common to backup windows, object ingest, and rebuild events. For enterprise security baselines, the 0B48714 integrates Self-Encrypting Drive capability with TCG Enterprise SSC to support hardware-based encryption and controlled decommission workflows.

Why Choose the 0B48714?

The 0B48714 delivers an efficient capacity-per-slot profile for bulk tiers, enabling higher usable TB per rack unit with fewer drives to manage across SAS domains. With a 2.5M hours MTBF reliability target, the 0B48714 supports standardized fleet deployment and predictable lifecycle planning in high duty-cycle environments, from dense JBOD shelves to multi-node RAID platforms.

WD designs Ultrastar datacenter drives with a focus on sustained operational stability, acoustics and power discipline, and compatibility with enterprise backplanes and controllers. This engineering approach aligns the 0B48714 to modern data center standards for security, manageability, and long-duration service in mixed-workload storage estates.

Key Applications:

• Bulk storage tiers
• Backup and archival repositories
• Object storage nodes
• SAS JBOD and RAID arrays
• Data lake capacity expansion
