Western Digital Ultrastar DC HC310 4TB 7200RPM SAS 12Gb/s 3.5-inch CMR Enterprise HDD

The Western Digital Ultrastar DC HC310 4TB is a 3.5-inch enterprise hard disk drive engineered for demanding datacenter environments requiring consistent throughput, high reliability, and sustained 24/7 operation. Built on Conventional Magnetic Recording (CMR) technology, the HC310 delivers predictable, write-consistent performance that is critical for transactional databases, high-density storage arrays, and workloads where data integrity cannot be compromised. The drive spins at 7,200 RPM and interfaces via SAS 12Gb/s dual-port connectivity, enabling full path redundancy and hot-plug capability in enterprise server and storage enclosure deployments.

The HC310 is rated for a workload of up to 550TB per year, reflecting its design lineage as a purpose-built enterprise drive rather than a repurposed nearline unit. With a mean time between failures (MTBF) rating of 2,000,000 hours and an annualized failure rate (AFR) of approximately 0.44%, the drive is positioned for mission-critical tier-2 storage, large-scale object storage clusters, and AI/ML data lake infrastructure where capacity density and data durability must coexist. The dual-port SAS interface supports multipath I/O configurations that eliminate single points of failure in enterprise SANs and JBODs.

Designed to operate across a wide range of enterprise storage platforms, the Ultrastar DC HC310 4TB (HUS726T4TAL5204) supports power loss protection and advanced error recovery controls (CCTL) that allow storage arrays to manage drive-level error handling without disruptive timeout events. The drive's 256MB cache buffer and support for SAS 12Gb/s full-duplex operation ensure that it sustains throughput in both sequential and random I/O profiles common to media repositories, backup and archive tiers, and hyperscale infrastructure deployments across datacenter environments in the UAE, GCC, EMEA, and APAC regions.

Ideal for

• High-density SAN and JBOD storage arrays requiring dual-port SAS redundancy and hot-plug drive replacement in tier-2 enterprise storage tiers
• AI and machine learning data lake infrastructure where large sequential read throughput and high annual workload ratings support continuous dataset ingestion and retrieval
• Enterprise backup and restore systems demanding CMR write consistency and sustained 24/7 operation across high-volume data protection workflows
• Transactional database secondary storage and log archive tiers where predictable latency and robust error recovery controls are essential for application stability
• Media and entertainment content repositories requiring reliable 7,200 RPM performance for large-file ingest, rendering scratch, and archival storage at scale
• Hyperscale object storage clusters and software-defined storage deployments in regional datacenter builds across GCC and APAC markets requiring high MTBF and low AFR drives
