0B34897 WD Ultrastar DC SS300 960GB SAS 2.5" Server SSD

Enterprise 2.5in SAS Hot-Swap Datacenter SSD for boot and read-intensive tiers with the 0B34897

The 0B34897 is a WD Ultrastar DC SS300 960GB enterprise SSD engineered for 24x7 server boot and read-intensive application volumes, where consistent latency and predictable QoS matter more than peak burst behavior. As a 2.5in SAS hot-swap drive, the 0B34897 integrates cleanly into standard backplanes and RAID/HBA configurations, supporting fast serviceability without disrupting node availability.

Built on TLC NAND with a data center–oriented controller and firmware, the 0B34897 is optimized for mixed but read-biased I/O patterns typical of virtualisation clusters and OS images. With sequential throughput up to 2100MB/s read and 1250MB/s write and random performance up to 400K IOPS 4K read and 120K IOPS 4K write, it accelerates boot storms and application start-up while maintaining stable behavior under consolidation. Power Loss Protection helps preserve in-flight data, and AES-256 with Instant Secure Erase supports secure lifecycle handling. Endurance is aligned to read-intensive tiers at 1DWPD (5 years), with 2.5M hours MTBF for enterprise deployment planning.

Why Choose the 0B34897?

The 0B34897 delivers an efficient density-to-performance profile for SAS-based servers that require hot-swap maintainability, controlled endurance, and consistent performance under continuous operation. It scales well across clustered nodes as a standardized boot and application SSD, reducing variability in rebuild and maintenance workflows while maintaining enterprise reliability and security controls.

WD designs Ultrastar data center SSDs with a focus on firmware stability, sustained workload predictability, and platform compatibility aligned to modern server and storage standards. This engineering approach supports long service life, operational consistency, and secure decommissioning across regulated environments.
