Western Digital Ultrastar DC HC310 4TB Hard Drive, SATA, SE, Designed for OEM, cloud deployments, and traditional IT systems, Leverages common hardware and firmware to minimize redundant testing needs, Advanced format 4Kn and 512e format models | 0B35950

The Ultrastar DC HC310 4TB (0B35950) is engineered for the rigorous demands of 24/7/365 data center operations. Unlike consumer-grade drives, the Ultrastar series is built for high-density environments where vibration, heat, and constant data access are the norm. This 4TB model offers a cost-effective entry point into enterprise-grade storage while maintaining the uncompromising reliability that Western Digital’s data center portfolio is known for.

Performance: Native 512n Format for Maximum Compatibility
The HUS726T4TALA6L4 features a native 512n (512 bytes per sector) format. This makes it an essential choice for legacy systems, older server architectures, and specialized industrial applications that cannot utilize the newer 512e or 4Kn advanced formats. With its 7200 RPM spindle speed, it delivers sustained transfer rates of up to 233 MB/s, making it ideal for high-transaction databases, enterprise backup, and video surveillance storage.

Durability: Built for High-Density Racks
In a multi-drive server chassis, rotational vibration can severely degrade performance and cause premature drive failure. The Ultrastar DC HC310 is equipped with advanced Rotational Vibration Safeguard (RVS) technology. This system uses integrated sensors to detect vibration in real-time and compensate the drive head’s position, ensuring consistent performance and mechanical longevity in racks with 16 or more drives.

Efficiency and Security
To help manage operational costs, the HC310 includes advanced power management features that allow for reduced power consumption during idle periods without sacrificing wake-up speed. Additionally, this drive is rated for a massive 550TB per year workload and a 2 million-hour MTBF, offering the peace of mind required for mission-critical business data.

Why the Ultrastar DC HC310 4TB Stands Out
CMR Technology: Reliable, high-speed write performance across the entire capacity.

Native 512n Support: Perfect for legacy hardware and enterprise RAID controllers.

Enterprise Endurance: Rated for 10 times the workload of a standard desktop drive.

RAID-Optimized: Features specialized error recovery control for consistent array performance.
