Western Digital Ultrastar DC HC310 8TB 7200RPM SATA 6Gb/s 3.5-inch CMR Enterprise HDD

The Western Digital Ultrastar DC HC310 8TB is a 3.5-inch enterprise-class hard disk drive engineered for demanding datacenter and cloud storage environments. Built on Conventional Magnetic Recording (CMR) technology, it delivers consistent, predictable write performance essential for mixed read/write workloads, transactional databases, and high-throughput storage systems. Spinning at 7200 RPM with a SATA 6Gb/s interface, the drive is designed to sustain continuous operation across dense server and storage array deployments.

The HC310 carries a workload rating of 550TB per year, positioning it well above consumer and nearline entry-level drives for environments requiring sustained I/O over extended duty cycles. With 256MB of DRAM cache, the drive optimizes sequential and random access patterns common in enterprise NAS, surveillance, and object storage platforms. Western Digital incorporates its HelioSeal technology in higher-capacity siblings of this family, and the HC310 shares the same enterprise-grade firmware stack, including enhanced error recovery controls (ERC/TLER) that allow compatibility with RAID controllers without drive fallout during recovery cycles.

Manufactured to operate within standard enterprise thermal and power envelopes, the Ultrastar DC HC310 8TB (manufacturer part number HUS728T8TALE6L4) is a proven choice for system integrators and IT procurement teams building out scalable storage infrastructure across datacenter, AI data pipeline, and archival workload tiers. Its SATA interface ensures broad compatibility with existing server platforms and JBODs without requiring additional HBA investment.

Ideal for

• High-density NAS and scale-out object storage arrays requiring reliable bulk capacity with CMR write consistency
• Surveillance and video analytics platforms demanding sustained write throughput across multi-camera, 24/7 recording workloads
• Enterprise backup and restore infrastructure where predictable sequential write performance and RAID compatibility are critical
• AI and machine learning data lake storage, providing cost-effective capacity for large training dataset ingestion and retrieval
• Virtualized server environments using RAID 5/6 or RAID-Z configurations that depend on TLER/ERC firmware support to prevent array degradation
• Colocation and cloud datacenter cold-to-warm tier storage, balancing capacity density with active workload accessibility
