HUS726T4TALA6L4 WD Ultrastar DC HC310 4TB SATA 256 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SATA HDD featuring CMR bulk storage architecture with the HUS726T4TALA6L4

The HUS726T4TALA6L4 is a 3.5in datacenter HDD engineered for capacity-tier storage where predictable latency and sustained throughput matter more than flash-level IOPS. In mixed server platforms, the HUS726T4TALA6L4 integrates cleanly behind standard SATA controllers and storage backplanes, enabling straightforward scaling in dense 4U and 2U storage nodes without consuming PCIe lanes needed for NICs, HBAs, or accelerators.

Built on CMR recording with a 512n sector format, the HUS726T4TALA6L4 supports consistent write behavior required by software-defined storage, general-purpose RAID arrays, and backup repositories. A 7200 RPM spindle and 256MB cache help stabilize sequential performance during rebuilds and large file operations, while Secure Erase support aligns with enterprise decommissioning workflows. With 24x7 duty-cycle expectations and power characteristics suited for always-on bays, the HUS726T4TALA6L4 is optimized for predictable thermals and operational continuity in shared datacenter racks.

Why Choose the HUS726T4TALA6L4?

The HUS726T4TALA6L4 delivers an efficient density-to-performance profile for capacity tiers, allowing architects to expand usable TB per chassis while keeping the platform simple and serviceable. With a 2.0M hour MTBF target and enterprise feature alignment, the HUS726T4TALA6L4 supports scalable deployments across replicated nodes, RAID sets, and SDS pools where reliability, controlled rebuild behavior, and fleet consistency are primary design constraints.

WD’s Ultrastar engineering prioritizes datacenter operational stability, focusing on component validation, firmware behavior under sustained workloads, and compliance with modern storage infrastructure standards for predictable integration and lifecycle management.

Key Applications:

• Server bulk storage
• Capacity tier for software-defined storage
• Backup and archive repositories
• General-purpose RAID arrays
• Always-on 24x7 enterprise storage bays
