Product information

Description

The Western Digital Ultrastar DC HC310 is a 3.5" internal hard drive with 4 TB capacity designed for data center and enterprise storage applications. Operating at 7200 RPM and featuring a 256 MB buffer, this SAS-drive variant delivers consistent access speeds and predictable performance for mixed workloads. The drive is built for sustained use with an MTBF rating suited for continuous operation and a form factor that fits standard 3.5" drive bays.

Advantages

The Ultrastar DC HC310 combines mid-range capacity with 7200 RPM spindle speed to provide a balance of economics and performance for server and storage deployments. Its large cache helps maintain throughput for large sequential transfers and mixed I/O patterns while the SAS interface enables reliable, enterprise-class connectivity. The drive’s engineering emphasizes durability for high-duty-cycle environments, making it suitable for sustained data-center workloads.

Suitable for

  • Rack and tower servers requiring 3.5" SAS drives
  • Block and file storage systems in enterprise environments
  • Distributed and scalable computing clusters
  • Applications with mixed read/write workloads and moderate to high annual data transfer

Key specifications

  • Capacity: 4000 GB
  • Form factor: 3.5 inch
  • Interface: SAS (serial attached SCSI)
  • Rotational speed: 7200 RPM
  • Buffer/cache: 256 MB
  • Designed workload: up to enterprise-class annual workload (refer to manufacturer guidance for exact rating)
  • Reliability (MTBF): 2,000,000 hours
  • Weight: 0.715 kg

How to use

Install the Ultrastar DC HC310 into a compatible 3.5" drive bay with a SAS host adapter or backplane that supports the drive’s interface. Secure the drive mechanically, connect the SAS data and power paths according to your server or enclosure documentation, and configure the drive in the host firmware or operating system. Initialize, partition and format the drive using standard storage management tools before placing it into production. Follow appropriate ESD precautions during handling.

Usage recommendations

For reliable operation, use the drive in systems with compatible SAS controllers and adequate cooling. Monitor SMART attributes and system logs to detect early signs of drive degradation. When deploying multiple drives, follow manufacturer guidelines for RAID or erasure coding configurations and maintain regular backups for critical data.
