About the WD Ultrastar HC590 26 TB 3.5 Inch SAS 12Gb/s Enterprise HDD 0F59375
With a 512 MB cache buffer and sustained transfer rate up to 272 MB/s, the WD Ultrastar HC590 26 TB 3.5 Inch SAS 12Gb/s Enterprise HDD delivers the performance characteristics required for high-capacity backup, NAS, and archive deployments. Built by Western Digital under the Ultrastar HC590 product family, this drive combines enterprise-grade reliability with substantial capacity in a compact 3.5-inch form factor. The dual-port SAS 12Gb/s interface enables multi-path connectivity, while the helium-sealed HelioSeal design and OptiNAND technology support sustained workloads of 550 TB/year with an annualized failure rate of just 0.35%. Powered by nine platters operating at 7200 RPM with conventional magnetic recording (CMR), this Western Digital solution achieves up to 272 MB/s throughput to handle demanding sequential I/O patterns typical of large-scale storage systems.
Storage architects and IT procurement teams responsible for data center expansions will recognize the HC590 as purpose-built for mission-critical environments where capacity density and reliability cannot be compromised. The 26 TB capacity minimizes the number of drives required per system, lowering chassis footprints and rack space consumption—a critical advantage in cost-conscious deployments. Rated for 600,000 load/unload cycles and engineered to tolerate operating temperatures from 5°C to 60°C, the drive suits both air-cooled and liquid-cooled installations. Active power consumption of 9.5 W and idle consumption of 5.0 W reflect efficient power delivery, reducing total cost of ownership across thousands of operating hours. The part number WUH722626AL5204 represents a fully qualified, field-proven solution available through established distribution channels.
Organizations standardizing on Western Digital enterprise storage infrastructure will find the Ultrastar HC590 26 TB model a natural fit within mixed-capacity deployments. Omnixon Global supplies this drive to regional and global enterprises requiring certified, documented hardware procurement.
