Hitachi Ultrastar DC HC670 26TB 7200RPM SATA 6Gb/s 3.5-inch Enterprise HDD

The Hitachi Ultrastar DC HC670 is a 26TB 3.5-inch enterprise hard disk drive engineered for high-density data center deployments requiring maximum capacity per drive bay. Built on Hitachi Vantara's ninth-generation HelioSeal platform, the HC670 uses helium-filled hermetic sealing to reduce internal air turbulence, enabling a ten-disk platter stack within the standard 3.5-inch form factor. The drive operates at 7200 RPM and interfaces via SATA 6Gb/s, delivering a sustained transfer rate suited to sequential read-intensive and mixed workloads at scale. A 512MB data buffer supports high-throughput streaming operations, and the drive is rated for 550TB per year workload, reflecting its positioning as a purpose-built enterprise storage device rather than a nearline desktop derivative.

The HC670 incorporates Hitachi Vantara's Advanced Format 512e sector technology, providing compatibility with legacy SATA infrastructure while supporting modern 4K-aligned I/O patterns. Rotational Vibration (RV) sensors are integrated to compensate for the mechanical interference introduced when multiple drives operate in high-density enclosures such as 60-bay or 90-bay JBODs, making the HC670 suitable for dense rack configurations without degraded performance. The drive also includes enhanced power management states to reduce idle power draw, which directly affects total data center power and cooling budgets at petabyte-scale deployments.

Target workloads for the Ultrastar DC HC670 include hyperscale object storage, cloud archive tiers, AI and machine learning training data repositories, video surveillance storage, and backup-to-disk infrastructure. Its combination of 26TB raw capacity, enterprise-grade reliability rated at 2.5 million hours MTBF, and a 550TB/year workload rating positions it as a foundational storage medium for organizations in data-intensive sectors including media and entertainment, financial services, genomics research, and large-scale cloud infrastructure buildouts across EMEA and APAC regions.

Ideal for

• Hyperscale object storage clusters requiring maximum raw capacity per rack unit, minimizing floor space and power consumption at petabyte scale
• AI and machine learning training data lakes where large sequential dataset reads from high-capacity spinning media serve GPU and accelerator pipelines
• Cloud archive and cold storage tiers in private and hybrid cloud environments where data retention at low cost-per-terabyte is a primary infrastructure objective
• High-density video surveillance storage platforms ingesting continuous multi-stream 4K footage requiring reliable high-capacity write endurance over extended periods
• Enterprise backup-to-disk and data protection appliances replacing tape in secondary and tertiary backup tiers within large-scale data center environments
• Genomics, scientific research, and media asset management repositories demanding dense, reliable bulk storage of large unstructured files accessed sequentially
