Hitachi Ultrastar DC HC560 20TB 7200RPM SATA 6Gb/s 3.5-inch Enterprise HDD (512e)

The Hitachi Ultrastar DC HC560 is a 20TB, 3.5-inch enterprise-class hard disk drive engineered on Hitachi Vantara's ninth-generation HelioSeal platform, utilizing helium-sealed enclosure technology to reduce internal air turbulence and enable higher areal density across nine platters. Operating at 7200 RPM with a SATA 6Gb/s interface and 512e sector format, the HC560 delivers a sustained transfer rate of up to 269 MB/s, making it one of the highest-capacity SATA drives available for large-scale data infrastructure.

Designed to meet the relentless throughput and endurance demands of modern enterprise environments, the HC560 carries a workload rating of 550 TB/year and a non-recoverable read error rate of 1 per 10^15 bits read. Its multi-stage actuator (MACH.2) dual-actuator architecture — available in select configurations — dramatically increases random I/O performance. The drive is built for continuous 24×7 operation and incorporates advanced features including Rotational Vibration Safeguard (RVS), PowerBalance technology for dynamic power optimization, and Helium-sealed hermetic design that contributes to lower power consumption relative to air-filled counterparts at equivalent capacity.

The Ultrastar DC HC560 is purpose-built to serve hyperscale cloud infrastructure, AI training storage pools, large-scale surveillance repositories, and high-density NAS or object storage deployments. Its combination of high sequential throughput, robust annualized failure rate (AFR) of 0.35%, and MTBF rating of 2.5 million hours positions it as a reliable, long-cycle storage foundation for enterprise IT and datacenter operators across demanding operational contexts.

Ideal for

• Hyperscale and cloud-tier object storage where maximum raw capacity per rack unit is critical to minimizing total infrastructure footprint
• AI and machine learning training data repositories requiring high-throughput sequential read performance to feed GPU compute pipelines efficiently
• High-density NAS and scale-out storage clusters for enterprise file services, backup targets, and long-term data retention
• Large-scale video surveillance storage systems operating in write-intensive, 24×7 continuous recording environments
• Cold and warm data archival tiers within tiered storage architectures, leveraging high capacity to reduce per-terabyte media count
• Enterprise backup and disaster recovery infrastructure where high capacity, sequential write throughput, and drive longevity are primary selection criteria
