0B34894 WD Ultrastar DC SS300 800GB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for Tiered Storage and Mixed Workloads with the 0B34894

The 0B34894 is a 2.5-inch hot-swap SAS enterprise SSD designed for consistent low-latency I/O in modern server and storage platforms, where predictable behavior matters more than peak bursts. Integrated into SAS backplanes and RAID/HBA designs, the 0B34894 supports cache, tiering, and database or virtualization pools that require stable mixed read/write performance under continuous duty cycles.

Built on MLC NAND, the 0B34894 targets sustained endurance at 10 DWPD over 5 years, enabling write-intensive operational profiles such as metadata-heavy virtualization, OLTP logging, and storage acceleration layers. Its SAS interface aligns with enterprise PCIe expansion strategies by offloading drive connectivity to proven SAS controllers, while hot-swap serviceability keeps maintenance windows short. Power loss protection, plus 256-bit AES encryption with Instant Secure Erase, helps preserve in-flight data integrity and supports security-controlled decommissioning workflows.

Why Choose the 0B34894?

The 0B34894 delivers an effective density-to-performance ratio for 2.5-inch bays, providing high random IOPS and strong sequential throughput for consolidated platforms. With 24/7 duty cycle design, 2.5M hours MTBF, and security features suitable for compliance-driven environments, the 0B34894 scales cleanly from a few drives in a server to larger SAS tiers in shared storage architectures.

WD engineers the Ultrastar DC SS300 family around enterprise qualification, predictable firmware behavior, and long-life operation within standard data center thermal and service models. This design focus supports consistent integration with SAS ecosystems and established operational tooling.

Key Applications:

• Enterprise read/write cache and storage tiering
• Database and OLTP mixed workloads
• Virtualization and VDI datastores
• Self-encrypting drive deployments
