Overview 

The WD Ultrastar DC HC590 is a 3.5-inch enterprise hard drive that delivers an impressive 24TB of storage capacity using Conventional Magnetic Recording (CMR) technology. Designed for 24/7 operation, it incorporates Western Digital's advanced OptiNAND technology and an innovative 11-disk helium-sealed platform to maximize storage density while maintaining outstanding reliability and power efficiency. Available with SATA 6Gb/s or SAS interfaces, the drive is optimized for cloud infrastructure, hyperscale data centers, enterprise servers, NAS systems, backup storage, and high-capacity archival applications. 

Key Features:

The WD Ultrastar DC HC590 combines several enterprise technologies that improve capacity, durability, and operational efficiency. Rather than focusing on consumer features, the drive prioritizes dependable performance over years of continuous service.

• Uses CMR technology for consistent, predictable performance
• Industry-first 24TB capacity achieved through an innovative 11-platter design within a standard 3.5-inch form factor.
• Energy-Assisted PMR (ePMR) for improved write performance and data integrity.
• 2.5 million-hour Mean Time Between Failures (MTBF) rating for exceptional long-term dependability.
• Built for read-intensive workloads, making it ideal for cloud storage, content delivery networks, and big data analytics.

Technical Specifications: 

Massive Storage Capacity

With an impressive 24TB of storage in a standard 3.5-inch form factor, the drive allows organizations to significantly store large datasets, virtual machine archives, media libraries, surveillance footage, backup images, analytics data, and cloud application content. Utilizing HelioSeal technology, the drive seals helium inside a standard 3.5-inch enclosure, drastically reducing internal mechanical turbulence and allowing paper-thin plies of aluminum substrates to rotate in close proximity. 

Disk Helium Platform

One of the standout innovations in the Ultrastar DC HC590 is Western Digital's proprietary OptiNAND technology, which combines traditional magnetic recording with integrated flash memory to optimize internal drive operations. Built on the world's first 11-disk helium-sealed CMR platform, the drive increases storage density while maintaining excellent thermal efficiency and reduced power consumption. The helium-filled design minimizes internal turbulence, enabling stable operation and enhanced long-term reliability even under continuous enterprise workloads. 

CMR Recording Technology

Unlike SMR drives that may experience performance limitations during sustained writes, the HC590 utilizes Conventional Magnetic Recording (CMR), providing consistent write performance and compatibility with enterprise RAID arrays, NAS systems, backup servers, and high-performance storage environments. The drive is available with both SATA 6Gb/s and SAS interfaces to accommodate diverse enterprise deployments. 

Enterprise Reliability

The Ultrastar DC HC590 is engineered for mission-critical applications that require uninterrupted operation. It features a projected Mean Time Between Failures (MTBF) rating of 2.5 million hours and supports enterprise workloads of up to 550TB per year. Western Digital also includes ArmorCache™ technology, allowing organizations to choose between enhanced random write performance and additional data protection during unexpected power loss events. These capabilities make the drive well suited for cloud computing, virtualization, large-scale databases, backup repositories, and object storage platforms. 

Design & Build Quality

The physical construction of the DC HC590 reflects its enterprise purpose. The drive uses a durable metal enclosure that helps protect internal components while improving structural rigidity during continuous operation. Unlike consumer drives that prioritize quiet desktop use, this model is built for professional installations where reliability and longevity remain the primary objectives.

Its 24TB CMR capacity, 7,200 RPM speed, up to 287 MB/s sustained transfer rate, enterprise workload rating, and 2.5-million-hour MTBF make it well suited to backup repositories, surveillance archives, NAS systems, cloud storage, and large data-center arrays. 

Frequently Asked Questions (FAQ)

1. Is this drive SMR or CMR?

The WUH722624AL5204 uses Conventional Magnetic Recording (CMR) technology. CMR delivers consistent write performance and is generally preferred for enterprise workloads, RAID arrays, and server environments because it avoids the performance limitations associated with SMR during sustained write operations.

2. Can it be used in a home NAS?

Yes, it can be installed in a home NAS if the system supports 12Gb/s SAS drives. Most consumer NAS units are designed for SATA drives, so compatibility should be confirmed before purchasing. It is often better suited for enterprise NAS systems and business storage appliances.

3. How does it compare to SSDs for bulk storage?

SDs provide much faster random access, lower latency, and quicker application loading. The WD Ultrastar DC HC590 excels in bulk storage, backups, archives, and large file repositories where storage capacity and cost per terabyte are more important than maximum speed.

4. What RAID configurations work best?

The drive performs well in several enterprise RAID configurations depending on business requirements. RAID 6 is commonly selected for large storage arrays because it provides strong fault tolerance. RAID 10 offers higher performance for workloads requiring faster access, while RAID 5 remains suitable for environments seeking a balance between usable capacity and redundancy.
