Western Digital Ultrastar DC HC310 4TB 7200RPM SATA 6Gb/s 3.5-inch CMR Enterprise HDD

The Western Digital Ultrastar DC HC310 4TB is a 3.5-inch enterprise-class hard disk drive engineered for demanding datacenter environments. Built on Conventional Magnetic Recording (CMR) technology, it spins at 7200 RPM and interfaces via SATA 6Gb/s, delivering consistent sequential throughput and low latency suited to high-duty-cycle server and storage deployments. The drive carries a workload rating of 550TB per year, reflecting its design for continuous 24×7 operation across multi-drive enclosures.

The HC310 4TB (HUS726T4TALE6L4) incorporates a 256MB cache buffer to smooth burst I/O and sustain throughput during intensive read/write cycles. Western Digital's HelioSeal hermetically sealed helium-fill platform is not employed at this capacity point; instead the drive uses a standard air-filled design optimised for the 4TB density tier. It supports advanced error recovery controls (AERC) and vibration compensation features that maintain performance integrity in dense multi-drive chassis subject to rotational vibration from neighbouring drives.

Targeted at enterprise storage arrays, cloud infrastructure, surveillance repositories, and AI training data lakes, the Ultrastar DC HC310 4TB fits workloads demanding high sequential throughput, dependable CMR write semantics, and a rated MTBF of 2,000,000 hours. Its SATA interface ensures broad compatibility across commodity server platforms and JBOD expansion shelves, making it a flexible building block for scalable capacity tiers in UAE, GCC, EMEA, and APAC datacenter deployments. Omnixon Global stocks this model for enterprise procurement across those regions.

Ideal for

• High-capacity NAS and SAN storage arrays requiring CMR write consistency and predictable rebuild times in multi-drive RAID configurations
• Hyperscale and colocation datacenters building warm or cold storage tiers for object storage platforms such as Ceph or MinIO
• AI and machine learning infrastructure where large training datasets must be ingested sequentially at sustained throughput rates
• Enterprise video surveillance back-end repositories handling continuous 24×7 write streams from high-channel-count camera systems
• Cloud service provider capacity expansion nodes where SATA compatibility, high MTBF, and per-terabyte density economics are priorities
• Enterprise backup and archival targets integrated with tape-replacement workflows demanding reliable CMR media for long-term data integrity
