The Ultrastar DC HC590 (WUH722626ALE6L4) represents the cutting edge of Western Digital’s high-capacity storage portfolio. Built on the proven 10-disk platform, this drive integrates UltraSMR (Shingled Magnetic Recording) technology to push areal density to its limits. It is specifically designed for sequential write workloads—such as big data archives, video surveillance, and cold storage—allowing data centers to store more data per rack than ever before.
Innovative Technology: UltraSMR and OptiNAND™
At the core of the HC590 is the OptiNAND™ platform, which integrates an iNAND UFS Embedded Flash Drive (EFD) with traditional rotating magnetic media. This allows for the UltraSMR recording format, which increases capacity by 10% or more over standard SMR. Additionally, the ArmorCache™ feature (enabled by OptiNAND) provides the performance of a write-cache-enabled drive while maintaining the data protection of a write-cache-disabled drive in the event of a power loss.
Enterprise-Class Performance and Reliability
The HC590 is built for 24/7/365 operation in the most demanding environments. It features a 2.5 million-hour MTBF and a workload rating of 550TB per year. The drive is helium-sealed (HelioSeal® technology), which significantly reduces internal friction and turbulence, resulting in lower operating temperatures and a power profile as low as 5.7W at idle. This makes it one of the most energy-efficient high-capacity drives on the market.
Hyperscale Efficiency and TCO
For large-scale deployments, the DC HC590 is the ultimate TCO tool. By offering 26TB in a single slot, it reduces the number of servers, cables, and floor space required for petabyte-scale storage. It supports the 512e Advanced Format for easy integration into existing enterprise infrastructures while offering robust hardware-based security features like Instant Secure Erase (ISE).
Why the Ultrastar DC HC590 Stands Out
UltraSMR Technology: Delivers up to 26TB, providing a significant density advantage over standard CMR drives.
OptiNAND™ Powered: Enhanced drive metadata management and improved data safety with ArmorCache™.
HelioSeal® Innovation: Lowers power consumption and improves mechanical reliability.
5-Year Limited Warranty: Comprehensive enterprise-level support.
