0B31079 WD Ultrastar SSD1600MR 1.6TB SAS 2.5" Server SSD

High-Performance 2.5-inch SAS Enterprise SSD for read-optimized tiers and secure hot-swap serviceability with the 0B31079

The 0B31079 is a 1.6TB 2.5-inch SAS enterprise SSD engineered for server backplanes where deterministic latency, hot-swap maintenance, and data-at-rest protection are required. Integrated into dual-port SAS storage domains, the 0B31079 supports read-optimized tiers and acceleration roles where high queue-depth reads and consistent response times improve metadata, index, and caching efficiency across virtualized clusters.

Built on MLC NAND, the 0B31079 balances sustained performance with endurance for mixed infrastructure patterns such as database logs and always-on transactional services. Its SAS interface aligns with enterprise RAID/HBA architectures, enabling predictable pathing and service continuity, while the hot-swap form factor supports rapid replacement without planned downtime. Self-encrypting drive capability helps standardize security controls at the device layer, simplifying compliance-driven designs without redesigning the storage stack.

Why Choose the 0B31079?

The 0B31079 delivers a practical density-to-performance profile for read-centric tiers in 24x7 environments, combining SAS operational maturity with hot-swap maintainability and SED security. By deploying the 0B31079 in front-end cache, metadata pools, or read-optimized volumes, infrastructure teams can scale IOPS where it matters most while keeping service procedures aligned with existing enterprise backplanes and redundancy models.

WD designs Ultrastar-class enterprise media for sustained duty cycles, emphasizing predictable behavior under load, validated firmware, and reliability characteristics expected in modern data centre storage domains. The platform focus is on integration with standard server storage ecosystems, supporting consistent operation across mixed virtualization and database-oriented deployments.

Key Applications:

• Read-optimized enterprise storage tiers
• Caching and acceleration layers
• Metadata and index repositories
• Virtualization datastores
• Database log and journal volumes
