Key Specifications and Performance Characteristics

Capacity and Form Factor Details

With a massive 14TB capacity, the Ultrastar DC HC530 (model 0F31002) provides one of the highest storage densities available in the enterprise market. The drive utilizes the standard 3.5-inch form factor with a height of 26.1mm, making it compatible with most enterprise servers and storage systems. The 4KN (4K Native) sector formatting ensures optimal alignment with modern file systems and applications, eliminating the performance overhead associated with emulation layers found in legacy sector formats.

Rotational Speed and Latency

The drive operates at 7,200 RPM, providing the ideal balance between performance, power consumption, and reliability for capacity-optimized enterprise workloads. This rotational speed delivers an average latency of 4.17ms, ensuring responsive access to stored data. The combination of high rotational speed with advanced caching algorithms enables the HC530 to maintain consistent performance under varying load conditions, making it suitable for both primary storage and nearline applications.

Interface and Data Transfer Capabilities

Equipped with a SAS (Serial Attached SCSI) 12Gbps interface, the Ultrastar DC HC530 delivers maximum theoretical transfer rates of up to 1,200MB/s. The dual-port capability of the SAS interface provides redundant data paths for high-availability configurations, ensuring continuous operation even in the event of a controller failure. The interface supports full duplex operation, allowing simultaneous read and write operations at full speed, and includes backward compatibility with 6Gbps SAS infrastructures.

Cache Buffer Implementation

The drive features a substantial 512MB DDR3 or DDR4 cache buffer (depending on manufacturing date) that serves multiple purposes: read-ahead caching for sequential operations, write caching with power-loss protection, and metadata storage. The large buffer size helps to smooth out performance fluctuations and maintain consistent throughput during sustained operations. Advanced algorithms optimize cache utilization based on workload patterns, automatically adjusting to maximize performance for both random and sequential access patterns.

Workload Rate and Duty Cycle

The 0F31002 HC530 is rated for 550TB per year workload, equivalent to approximately 1.5TB of writes per day, making it suitable for write-intensive enterprise applications. With a 100% duty cycle rating, the drive is engineered for continuous 24/7 operation without performance degradation. This workload capability ensures the drive can handle the demanding requirements of cloud storage, data analytics, content delivery networks, and other enterprise applications where constant data access is required.

Error Correction and Data Integrity

Advanced error correction capabilities include Toshiba's third-generation MAMR (Microwave-Assisted Magnetic Recording) technology combined with Western Digital's HelioSeal platform, enabling reliable data storage at ultra-high densities. The drive implements sophisticated error correction codes (ECC) that can detect and correct errors in real-time, preventing data corruption and ensuring data integrity throughout the drive's operational life. These features are particularly critical in large-scale storage arrays where data reconstruction times can be extensive.

Power Efficiency

Power Consumption Specifications

The helium-filled design significantly reduces power requirements compared to air-filled drives of similar capacity. Typical power consumption during active operations is approximately 5.5-6.5 watts, while idle power consumption drops to approximately 4.5-5.5 watts. The drive supports multiple power management states, including standby and sleep modes, which can reduce power consumption to less than 1 watt during periods of inactivity. These efficiency characteristics translate to substantial power savings in large-scale deployments.

Acoustic Performance

The helium platform not only improves power efficiency and thermal performance but also significantly reduces acoustic noise. The Ultrastar DC HC530 operates at just 20 dBA in idle mode and 28 dBA during seek operations, making it one of the quietest high-capacity enterprise drives available. This acoustic profile is particularly beneficial in open-rack data center environments where noise reduction contributes to improved working conditions for technical staff.

Wide Compatibility

Form Factor and Mounting Compatibility

The standard 3.5-inch form factor with enterprise-standard mounting holes ensures compatibility with most server and storage system chassis. The drive's 26.1mm height conforms to the standard for 3.5-inch enterprise drives, allowing seamless integration into existing infrastructure. The SAS interface provides broad compatibility with enterprise RAID controllers, HBAs, and storage systems from major manufacturers including Dell EMC, HPE, IBM, and Supermicro.

4KN Sector Format Advantages

The 4KN (4K Native) sector format aligns with modern operating systems and file systems that utilize 4KB clusters, eliminating the read-modify-write penalty associated with 512e emulated drives. This native 4K alignment improves performance for most enterprise workloads and simplifies storage stack management. The HC530 does not support 512-byte sector emulation, ensuring optimal performance and compatibility with modern enterprise infrastructure designed for 4K-native storage devices.

Firmware Features and Management Capabilities

The 0F31002 Ultrastar DC HC530 includes comprehensive firmware features for enterprise management, including SCSI Enclosure Services (SES), Temperature Logging, Self-Monitoring, Analysis and Reporting Technology (SMART), and Power Loss Protection. These features enable proactive health monitoring, predictive failure analysis, and seamless integration with enterprise management frameworks. The drive's firmware is optimized for consistent Quality of Service (QoS), ensuring predictable performance in multi-drive configurations.

Data Security Options

While the base model (0F31002) does not include hardware encryption, compatible secure models are available for environments requiring FIPS 140-2 compliant data-at-rest encryption. These secure variants provide cryptographic sanitization capabilities and instant secure erase functionality, meeting the requirements for sensitive data handling in regulated industries. The encryption implementation is transparent to the host system and maintains full performance while providing comprehensive data protection.

Use Cases and Application Scenarios

Cloud Storage Infrastructure

The Ultrastar DC HC530 is ideally suited for cloud storage platforms where capacity density, power efficiency, and total cost of ownership are primary considerations.
