Western Digital Ultrastar DC HC330 10TB 7200RPM SATA 6Gb/s 3.5-inch CMR Enterprise HDD

The Western Digital Ultrastar DC HC330 is a 10TB 3.5-inch enterprise-class hard drive engineered for demanding datacenter and cloud infrastructure environments. Built on Conventional Magnetic Recording (CMR) technology, it delivers consistent, predictable write performance critical for mixed-workload enterprise applications. Operating at 7200 RPM with a SATA 6Gb/s interface, the HC330 is designed to sustain continuous operation across high-density storage deployments where reliability and throughput are non-negotiable.

The HC330 incorporates Western Digital's HelioSeal technology, filling the hermetically sealed enclosure with helium to reduce internal turbulence, lower power consumption, and extend component longevity compared to air-filled drives. This architecture enables a higher areal density with multiple platters in a standard 3.5-inch form factor while maintaining thermal stability under sustained I/O pressure. The drive supports a workload rating of up to 550TB per year, reflecting its suitability for write-intensive enterprise tasks including backup, archival, and always-on surveillance or analytics pipelines.

With a mean time between failures (MTBF) rating of 2.5 million hours and support for dual-plane balance, vibration compensation, and rotational vibration safeguard (RVS) technology, the Ultrastar DC HC330 is purpose-built for multi-drive chassis environments such as JBODs, NAS arrays, and high-density rack-mounted storage servers. Its compatibility with enterprise operating systems and storage platforms makes it a dependable component for AI data repositories, object storage clusters, and large-scale content repositories across UAE, GCC, EMEA, and APAC datacenter deployments.

Ideal for

• High-density object storage and cloud-scale data repositories requiring sustained write throughput and long-term drive reliability
• Enterprise backup and disaster recovery infrastructure where consistent CMR write behavior and high workload ratings are essential
• AI and machine learning data lake storage, providing high-capacity sequential read performance for training dataset ingestion
• Surveillance and video analytics platforms demanding continuous 24/7 write cycles across multi-drive enclosures
• Hyperscale and colocation datacenter storage tiers where helium-sealed drives deliver reduced power draw per terabyte
• NAS and JBOD arrays in enterprise environments benefiting from rotational vibration safeguard for stable multi-drive operation
