Key Features

11-Disk High-Density Architecture

Maximizes storage capacity within a standard 3.5-inch form factor, enabling higher data density per rack unit and reducing overall infrastructure footprint.

Up to 26TB CMR Capacity

Provides enterprise-grade storage scalability with Conventional Magnetic Recording (CMR) for consistent performance and predictable data integrity.

Dual Interface Flexibility (SATA / SAS)

Supports both SATA 6Gb/s and SAS 12Gb/s environments, allowing seamless integration into diverse enterprise storage architectures.

Advanced Vibration Protection (RVS + Dynamic Fly Height)

Maintains performance stability in multi-drive systems by actively compensating for rotational vibration and mechanical disturbances.

OptiNAND Technology Integration

Improves drive efficiency and metadata management by leveraging embedded flash for enhanced internal operations and performance optimization.

ArmorCache Write Optimization

Enhances random write performance while ensuring data protection in unexpected power-loss scenarios, balancing speed and resilience.

HelioSeal Helium Platform

Reduces internal friction and heat generation, resulting in lower power consumption and improved long-term reliability in always-on environments.

Performance and Reliability

The HC590 delivers sustained transfer speeds of up to 302MB/s, ensuring stable throughput for large-scale sequential workloads such as backup, archiving, and analytics processing.

With a 2.5 million-hour MTBF rating and 550TB/year workload capability, it is designed for enterprise environments that demand continuous availability and predictable performance under heavy utilization.

This makes it particularly suitable for hyperscale cloud storage, AI training datasets, and distributed storage infrastructures.
