0B26925 WD Ultrastar 7K4000 2TB SAS 64 MB 3.5" Server HDD

High-Performance 3.5in Enterprise SAS HDD for 24x7 Capacity Tiers with the 0B26925

The 0B26925 is a WD Ultrastar 7K4000 3.5in internal enterprise HDD engineered for consistent, predictable block storage in server and RAID environments where cost-per-GB and serviceability matter. As a 7200 RPM, CMR drive with 512n sector formatting and a 64MB cache, the 0B26925 supports stable write behavior and rebuild characteristics that are critical for always-on capacity tiers and mixed read/write workloads.

Designed around a SAS single-port interface, the 0B26925 integrates cleanly into 12Gb/s SAS backplanes, JBOD shelves, and classic RAID controllers, allowing straightforward scaling of disk groups without changing the host platform. The 2TB capacity and rotational profile position the 0B26925 for OS/boot pools, bulk data volumes, and nearline tiers where latency is secondary to steady throughput, queue depth handling, and operational continuity across large drive counts.

Why Choose the 0B26925?

The 0B26925 delivers an enterprise-focused density-to-performance balance for capacity-oriented arrays while maintaining the reliability profile expected in 24x7 service. With a 2.0M-hour MTBF rating and controlled power behavior, the 0B26925 is well suited for scalable deployments where fleet consistency, predictable rebuild windows, and operational risk reduction drive the storage architecture.

WD designs Ultrastar platforms with a focus on datacentre-grade validation, sustained duty cycles, and interoperability with common server and storage standards. For long-lived infrastructures, WD emphasizes predictable behavior under load, qualification discipline, and lifecycle continuity that supports standardization across racks and sites.
