Backed by Western Digital’s rigorous quality standards, it’s designed for 24/7 operation in mission-critical environments.

SAS 12Gbps Interface: Speed and Reliability Combined

The Ultrastar DC HC580 0F62835 utilizes the SAS 12Gbps interface, which offers dual-port functionality for high-availability architectures. Unlike SATA, SAS provides better error correction, improved signal integrity, and higher throughput, making it the preferred interface for enterprise applications. This interface ensures compatibility with enterprise RAID controllers and JBODs.

Enterprise-Grade Data Transfer

With a sustained data transfer rate that meets the high-performance demands of cloud storage arrays and enterprise SAN environments, the 12Gbps SAS interface ensures fast and consistent data movement. This reduces latency in storage-intensive workloads such as video editing, content streaming, and virtualization.

Dual Port Connectivity

The dual-port nature of SAS offers failover redundancy, ensuring uninterrupted data access even if one channel fails. This is particularly critical in data centers where downtime or data inaccessibility can lead to costly consequences. Dual ports also enhance load balancing and performance scalability in clustered systems.

OptiNAND Technology Explained

OptiNAND is a proprietary Western Digital innovation that integrates NAND flash with traditional spinning disk architecture. In the Ultrastar DC HC580, this hybrid design enhances performance, reliability, and capacity management by storing metadata and firmware in NAND instead of on the spinning platter.

Benefits of OptiNAND

• Improved Performance: Offloading metadata from platters to NAND reduces seek times and enhances data write efficiency.
• Better Reliability: Critical system data stored in NAND can be preserved during power loss, reducing the risk of corruption.
• Capacity Optimization: With more platter space freed up for user data, the drive achieves higher storage density without increasing the form factor.

Power Loss Protection

OptiNAND enables power loss protection by instantly transferring write cache to NAND during sudden power interruptions. This ensures that mission-critical applications can maintain data integrity even in unstable power environments.

Higher Areal Density

OptiNAND’s metadata offloading allows for greater areal density on the platters, enabling Western Digital to push storage limits within the same physical footprint. This means more data per drive, which is crucial for data centers scaling efficiently.

7200 RPM and 512MB Cache for Enhanced Throughput

With a spindle speed of 7200 RPM and an onboard cache of 512MB, the Ultrastar DC HC580 ensures rapid access to frequently used data and efficient sequential read/write operations. This is especially beneficial for data streaming and real-time data processing.

Faster Data Access Speeds

The large cache size allows the drive to buffer significant chunks of data, reducing latency for burst-heavy applications. Combined with 7200 RPM speed, this results in lower seek times and more consistent IOPS performance.

Ideal for Sequential Workloads

The 512MB cache is advantageous for workloads involving large file transfers or media content delivery, where sequential read/write patterns dominate. It minimizes I/O bottlenecks and improves user experience in cloud-hosted applications.

3.5-Inch Form Factor Standardized and Scalable

The industry-standard 3.5-inch form factor allows seamless integration with existing enterprise hardware, from servers to NAS systems. It supports rack scalability and minimizes infrastructure overhaul costs when upgrading to higher-capacity drives like the 0F62835.

Plug-and-Play Compatibility

Designed for drop-in compatibility, the Ultrastar DC HC580 can replace older drives in data center racks without modification. Its adherence to industry specifications ensures universal deployment across server brands and storage platforms.
