0B34895 WD Ultrastar DC SS300 1.6TB SAS 2.5" Server SSD

High-Performance 2.5in SAS Enterprise SSD for Tiering and Caching with the 0B34895

The 0B34895 is a 1.6TB 2.5in SAS hot-swap enterprise SSD engineered for consistent low-latency storage in 24x7 datacenter environments, where SAS backplanes, dual-path connectivity, and predictable serviceability are required. Designed for RAID arrays and shared storage shelves, the 0B34895 aligns with modern server platforms that prioritize fault tolerance and controlled maintenance windows while sustaining high sequential throughput for mixed read/write activity.

Using MLC NAND and an endurance profile rated at 10 DWPD over 5 years, the 0B34895 supports write-intensive tiers and read/write caching layers without compromising fleet consistency. Power-loss protection stabilizes in-flight data during unexpected events, while SAS architecture simplifies integration into PCIe expansion and HBA-based topologies across virtualization clusters, database nodes, and software-defined storage. For security-driven deployments, the 0B34895 implements 256-bit AES self-encrypting drive capability with Instant Secure Erase to streamline decommissioning workflows.

Why Choose the 0B34895?

The 0B34895 delivers a strong density-to-performance ratio in a standardized 2.5in hot-swap form factor, enabling administrators to scale throughput and IOPS per chassis without redesigning the storage plane. With 2.5M hours MTBF and enterprise SAS behavior under sustained load, the 0B34895 supports predictable scaling for tiered architectures, cache acceleration, and latency-sensitive services across multi-node deployments.

WD designs Ultrastar datacenter storage with a focus on long-life media management, controlled failure modes, and operational consistency in large fleets. This engineering approach supports standard data centre practices such as hot-swap servicing, secure lifecycle handling, and compatibility with enterprise SAS ecosystems.
