0B36048

Enterprise 3.5in SAS Datacenter HDD engineered for capacity tiers and secure retention with the 0B36048

The 0B36048 is a 4TB WD Ultrastar DC HC310 3.5in internal SAS HDD designed for server and storage array capacity layers where predictable throughput, consistent latency, and 24x7 duty cycles are required. As a 7200RPM platform with 256MB cache, the 0B36048 supports steady sequential transfer patterns and mixed read/write behavior typical of capacity pools, backup landing zones, and general-purpose datacenter storage.

Built around a single-port SAS interface, the 0B36048 integrates cleanly into enterprise backplanes and SAS HBAs, enabling controlled scaling through established expander and RAID topologies. The 512e (4Kn with 512-byte emulation) sector format eases integration with existing operating systems and storage software while maintaining modern media formatting under the hood. For security-sensitive retention, the 0B36048 includes hardware-based Self-Encrypting Drive (SED) capability, supporting secure data-at-rest requirements without relying on host-side encryption overhead.

Why Choose the 0B36048?

The 0B36048 is optimized for high-density capacity deployment where cost-efficient terabytes per rack unit must still meet enterprise expectations for reliability and manageability. With a 2.0M hour MTBF rating, the 0B36048 fits scale-out architectures that demand consistent lifecycle behavior across large drive populations, supporting predictable fleet operations, spares planning, and RAID rebuild strategies in always-on environments.

WD’s Ultrastar engineering focuses on datacenter-grade endurance, controlled power behavior, and compatibility with standard server and storage array designs. This approach supports modern operational requirements such as secure handling, long service intervals, and stable integration across heterogeneous platforms.

Key Applications:

Server and storage array capacity tiers
Archive and backup repositories
General-purpose datacenter storage
Nearline retention pools

At Happyware - Server Hardware you benefit from non-binding offers tailored to your rollout requirements and an extended warranty of up to 6 years to align the 0B36048 with long-term datacenter maintenance and budgeting cycles.
