Western Digital Ultrastar DC HC330 10TB 7200RPM SAS 12Gb/s 3.5-inch CMR Enterprise HDD

The Western Digital Ultrastar DC HC330 10TB is a 3.5-inch enterprise-class hard disk drive built on Conventional Magnetic Recording (CMR) technology and engineered for continuous 24/7 operation in demanding datacenter environments. Spinning at 7200 RPM with a SAS 12Gb/s interface, it delivers sustained sequential read performance up to 249 MB/s and incorporates a 256 MB cache buffer to support high-throughput workloads. The drive is rated for up to 550 TB per year (TBW) workload rating, reflecting its suitability for write-intensive enterprise applications where data integrity and endurance are critical requirements.

The HC330 leverages HelioSeal technology, with the drive hermetically sealed and filled with helium to reduce internal air turbulence, lower operating temperatures, and decrease power consumption relative to air-filled designs. This architecture enables Western Digital to stack multiple platters within the standard 3.5-inch form factor while maintaining mechanical stability and reducing the per-TB power envelope. The drive supports dual-port SAS connectivity, providing path redundancy essential for enterprise storage arrays, RAID configurations, and high-availability server infrastructure.

Designed to integrate directly into enterprise storage platforms, JBODs, and SAN environments, the Ultrastar DC HC330 includes Western Digital's RAFF (Rotational Acceleration Feed Forward) technology for vibration compensation in multi-drive chassis deployments. Additional data protection features include end-to-end data path protection and optional Self-Encrypting Drive (SED) variants. With a 2.5 million hour MTBF rating, the HC330 is positioned for mission-critical roles where drive reliability, sustained throughput, and scalable capacity intersect.

Ideal for

• Hyperscale and colocation datacenter storage arrays requiring high-density, high-endurance CMR drives for object storage and bulk data repositories
• AI and machine learning infrastructure where large training datasets must be stored and retrieved at sustained sequential throughput across multi-drive enclosures
• Enterprise NAS and SAN systems demanding dual-port SAS redundancy and 24/7 continuous duty cycle operation in high-availability configurations
• Surveillance and video analytics platforms ingesting and retaining high-bitrate video streams across extended retention periods at scale
• Cloud service provider and managed hosting environments building cost-efficient, high-capacity storage tiers for warm and cold data archival
• Enterprise backup and restore infrastructure requiring high sequential write endurance and workload ratings that support frequent full-backup cycles
