0B34964 WD Ultrastar DC SS300 3.2TB SAS 2.5" Server SSD

High-Performance 2.5in SAS Datacenter SSD featuring read-optimized endurance with the 0B34964

The 0B34964 is a WD Ultrastar DC SS300 3.2TB 2.5in SAS enterprise SSD designed for always-on server and storage platforms where predictable latency and sustained read performance matter. Integrated into SAS backplanes, it supports hot-swap serviceability and aligns with common enterprise RAID/HBA topologies for rapid replacement and minimal maintenance windows.

Built on MLC NAND, the 0B34964 targets read-intensive tiers and caching with an endurance profile of 3 DWPD for 5 years, enabling continuous virtualization and database log or temp volume operation. Its SAS interface delivers up to 2100 MB/s read and 2050 MB/s write, while 4K random performance up to 400,000 read IOPS and 170,000 write IOPS supports dense VM consolidation and metadata-heavy workloads. Power Loss Protection helps preserve in-flight data during unexpected outages, and Secure Erase supports controlled decommissioning and compliance workflows in shared data centre environments.

Why Choose the 0B34964?

The 0B34964 delivers a balanced density-to-performance ratio for read-centric enterprise storage designs, providing predictable service levels without oversizing capacity or endurance. Its hot-swap 2.5in form factor simplifies scaling within SAS shelves and server backplanes, while the reliability profile supports 24/7 duty cycles in operationally constrained racks.

WD engineers Ultrastar SSDs for data centre consistency, emphasizing controlled write behavior, strong data-path protection, and qualification against enterprise SAS infrastructures. The design focus aligns with modern operational standards for fleet deployment, lifecycle management, and uptime-centric maintenance procedures.
