HUS726T4TALN6L4 WD Ultrastar DC HC310 4TB SATA 256 MB 3.5" Server HDD

High-Density 3.5in Datacenter HDD for SATA Nearline Storage with the HUS726T4TALN6L4

The HUS726T4TALN6L4 is a 3.5in internal datacenter HDD engineered for predictable throughput and continuous operation in enterprise SATA storage tiers. As a 4TB, 7200 RPM platform using CMR media and 4Kn (4KB native) sectors, it aligns with modern host and controller designs that prioritise consistent write behaviour, stable latency, and clean rebuild characteristics in multi-drive enclosures.

Designed for server bulk storage and nearline capacity, the HUS726T4TALN6L4 integrates efficiently into SATA JBOD/backplane environments and RAID arrays where PCIe expansion is reserved for accelerators, NICs, or NVMe caching. The drive’s 256MB cache supports burst absorption and command reordering, while 4Kn formatting reduces sector management overhead in compatible stacks. Secure Erase (SE) enables controlled decommissioning workflows to support datacenter security and asset lifecycle policies.

Why Choose the HUS726T4TALN6L4?

The HUS726T4TALN6L4 delivers a balanced density-to-performance profile for high-bay storage nodes that need cost-efficient capacity without sacrificing operational discipline. With a 24x7 duty cycle orientation and 2.0M hours MTBF, the HUS726T4TALN6L4 supports scalable population of RAID groups and large JBOD shelves, helping standardise spares and simplify capacity planning across distributed storage pools.

WD builds the Ultrastar family around enterprise validation, consistent firmware behaviour, and long-life mechanics tuned for rack-scale deployments. The HUS726T4TALN6L4 reflects this focus with datacenter-grade reliability targets, power-aware operation, and feature alignment for controlled sanitisation and predictable integration into standard SATA infrastructures.

Key Applications:

• Nearline bulk storage
• RAID arrays in SATA JBOD shelves
• Backup and archive repositories
• Content and media libraries
• Log retention and compliance storage
