Key Technologies and Innovations in the HC590 Series

The Ultrastar DC HC590 series integrates some of Western Digital’s most advanced storage technologies. These innovations are aimed at enhancing reliability, increasing data throughput, and maximizing storage density.

OptiNAND Technology Explained

One of the standout features of the 0F59373 drive is Western Digital’s OptiNAND technology. This combines traditional spinning disk (HDD) technology with NAND flash memory to improve data integrity and enable higher areal density. The embedded NAND stores metadata and firmware management data separately from the disk, freeing up valuable disk space and allowing for enhanced performance in write operations, especially during sudden power loss situations.

HelioSeal Technology

The HC590 employs HelioSeal technology, which uses helium instead of air inside the drive. This reduces internal turbulence, lowers friction, and improves overall efficiency. The result is less power consumption, better thermal performance, and increased reliability over traditional air-filled drives.

Energy-Assisted Magnetic Recording (EAMR)

To achieve such high capacity within a 3.5-inch footprint, the HC590 leverages Energy-Assisted Magnetic Recording. This technique enables a higher number of tracks per inch without compromising reliability or increasing write errors, crucial for enterprise workloads demanding both density and performance.

Enterprise-Class Features for Mission-Critical Operations

The 0F59373 model is tailored for modern enterprise storage arrays and hyperscale data center environments where reliability and data integrity are essential.

Enterprise Workload Ratings

With a 550TB per year workload rating, this drive is capable of handling intense read/write operations. The high MTBF (Mean Time Between Failures) of 2.5 million hours makes it a dependable choice for 24/7 operations in demanding storage infrastructures.

SAS 12Gbps Interface

The Serial Attached SCSI (SAS) 12Gbps interface ensures fast, reliable, and secure data transfer. SAS also allows for dual-port access, increasing redundancy and failover capability in storage arrays. This makes the 0F59373 an excellent choice for RAID configurations, high-availability clusters, and virtualization environments.

512MB Cache Buffer

The integrated 512MB cache enhances performance by preloading frequently accessed data and minimizing latency during high I/O operations. This is especially beneficial in transactional databases, analytics workloads, and other IOPS-intensive applications.
