WD Ultrastar DC HC590 3.5" 26TB, 7200 RPM, 512MB, 550 WRL, SAS Hard Drive, Enterprise

The Western Digital Ultrastar DC HC590 is a high-capacity internal hard drive engineered for data center storage environments. It utilizes a Conventional Magnetic Recording (CMR) platform to deliver 26 TB of storage capacity. The drive is designed to meet demands for increased storage density within standard server and storage system footprints, serving enterprise-level applications that require large-scale data retention.

This model operates at a 7200 RPM spindle speed and includes a 512 MB cache to facilitate data access. Its 12 Gbit/s SAS interface provides a high-throughput connection suitable for demanding workloads. Built for continuous operation, the drive is rated for a 550 TB/year workload and a Mean Time Between Failures (MTBF) of 2.5 million hours. Integrated Rotational Vibration (RV) sensors help maintain performance integrity in dense, multi-drive systems. Hardware-based self-encryption and end-to-end data protection are included for data security.
