0B34902 WD Ultrastar 800GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for Mixed Workloads and Secure Storage with the 0B34902

The 0B34902 is a WD Ultrastar DC SS300 2.5-inch SAS enterprise SSD designed for server and storage backplanes that require consistent latency under mixed read/write pressure. Built for 12Gb/s SAS infrastructures, the 0B34902 integrates cleanly into existing dual-port SAS topologies, enabling resilient paths in shared storage and high-availability clusters while keeping upgrade cycles aligned with established SAS ecosystems.

Architected for database, VM boot, and cache tiers, the 0B34902 combines high sequential throughput with strong 4K IOPS to accelerate metadata-heavy and transactional patterns. Its endurance profile supports sustained write activity, while power-loss protection helps preserve in-flight data during unexpected outages. For secure environments, the 0B34902 adds hardware-based encryption with rapid sanitization capabilities, supporting controlled decommissioning without disrupting operational processes.

Why Choose the 0B34902?

The 0B34902 targets enterprise deployments where a predictable density-to-performance ratio is required across many bays, with SAS serviceability and dual-path reliability as core design assumptions. The 0B34902 scales effectively in storage shelves and rack servers by maintaining consistent behavior under contention, supporting standardized fleet operations, and reducing risk in security-sensitive rollouts.

WD engineers the Ultrastar portfolio for continuous duty cycles, platform qualification depth, and long-life data center operation. With the 0B34902, this focus translates into enterprise reliability characteristics, controlled power behavior, and security features aligned with modern compliance and lifecycle management practices.

Key Applications:

• Mixed read/write enterprise storage tiers
• Database acceleration and log workloads
• VM boot and VDI image stores
• Server-side caching and metadata acceleration
• Secure deployments requiring SED and fast sanitization
