0B35048 WD Ultrastar DC SS300 3.2TB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Datacenter SSD for write-intensive tiers with the 0B35048

The 0B35048 is a 3.2TB 2.5-inch SAS hot-swap SSD engineered for 24/7 enterprise storage tiers where low latency and sustained write behavior are decisive. Integrated into SAS backplanes and dual-path architectures, the 0B35048 aligns with modern server and storage array designs that prioritize predictable QoS for database logs, virtualization write cache, and tiering layers.

Built on MLC NAND, the 0B35048 targets write-intensive duty cycles with endurance rated at 10 DWPD and a 5-year profile, enabling dense consolidation without sacrificing lifecycle planning. The SAS interface supports robust command queuing and enterprise multipath, while the storage architecture incorporates Power Loss Protection to preserve in-flight data and metadata. For security-constrained environments, the 0B35048 adds 256-bit AES encryption with Instant Secure Erase to streamline decommissioning and compliance workflows.

Why Choose the 0B35048?

The 0B35048 delivers a balanced density-to-performance ratio for mixed storage stacks, pairing hot-swap serviceability with enterprise reliability for continuous operation. With high sequential throughput and strong endurance, the 0B35048 scales effectively from single-node servers to shared SAS arrays, supporting consistent performance under sustained write pressure and simplifying standardized fleet deployments.
