0B34899 WD Ultrastar DC SS300 3.86TB SAS 2.5" Server SSD

High-Density 2.5-inch SAS Enterprise SSD for Secure Boot and Read-Intensive Tiers with the 0B34899

The 0B34899 is a WD Ultrastar DC SS300 2.5-inch hot-swap SAS enterprise SSD engineered for datacenter internal drive bays where predictable latency, secure handling, and operational continuity are mandatory. Positioned for OS boot, cache, and read-intensive tiers, the 0B34899 combines a SAS 12Gb/s interface with TLC NAND to support stable performance characteristics in shared storage backplanes and high-availability server platforms.

Architecturally, the 0B34899 supports modern SAS infrastructures that prioritize dual-port paths, controller redundancy, and serviceable drive cages. With throughput up to 2100 MB/s read and 1250 MB/s write and 4K random performance reaching up to 400k read IOPS, the 0B34899 is well-aligned to metadata acceleration, VM image hosting, and general compute pools requiring balanced mixed I/O. Endurance is rated at 1 DWPD over 5 years and 7000 TBW, while Power Loss Protection helps protect in-flight data during unexpected outages, supporting consistent recovery behavior in transactional environments.

Why Choose the 0B34899?

The 0B34899 delivers an efficient density-to-performance profile for SAS-based servers that must maintain hot-swap serviceability and centralized storage governance. By pairing enterprise reliability (2.5M hours MTBF, 24x7 duty cycle) with hardware encryption and secure erase capabilities, the 0B34899 scales cleanly across standardized fleets without compromising security controls or operational uptime expectations.

WD designs the Ultrastar portfolio around datacenter qualification, consistent firmware behavior, and platform interoperability, enabling controlled deployment in regulated environments. With the 0B34899, enterprises gain a drive engineered for sustained service life, predictable power characteristics, and compatibility with established SAS management and monitoring practices.
