Enterprise-Grade Reliability and Performance

The Ultrastar DC HC550 is engineered to meet the demands of modern enterprise applications. Designed with conventional magnetic recording (CMR) technology, it ensures stable performance and long-term reliability in data centers. This drive is optimized for workloads requiring high throughput and consistent response times, making it ideal for cloud storage, big data analytics, and high-volume transactional processing.

Helium-Sealed Technology for Enhanced Efficiency

Western Digital employs its advanced HelioSeal™ technology, which replaces conventional air-filled drives with a helium-sealed design. This significantly reduces friction, resulting in lower power consumption, decreased heat generation, and extended drive longevity. With up to 30% lower energy usage compared to air-based drives, the HC550 is a greener, more cost-effective solution for large-scale storage environments.

Lower Power Consumption for Data Centers

The efficiency of helium technology reduces the drive’s power requirements, leading to substantial savings in operational costs. With a lower power draw of approximately 5.6W at idle and 7.8W during operation, it minimizes energy consumption while maintaining peak performance.

Enhanced Data Protection with 512e ISE Technology

The 512e ISE (Instant Secure Erase) feature enhances data security by allowing for swift and complete erasure of sensitive information. This is particularly valuable for enterprises requiring quick drive retirement or repurposing without the risk of data breaches. The 512e format ensures compatibility with modern storage architectures while maximizing capacity utilization.

Superior SAS-12Gbps Interface for High-Speed Data Transfer

Equipped with a SAS-12Gbps interface, the Western Digital Ultrastar DC HC550 provides faster and more reliable data access compared to traditional SATA drives. The SAS interface enables enterprise servers and storage arrays to handle demanding workloads efficiently while reducing latency.
