Western Digital Ultrastar DC SN840 3.84TB NVMe SSD

The Western Digital Ultrastar DC SN840 is a dual-port NVMe SSD engineered for high-availability enterprise environments requiring concurrent host access and mission-critical reliability. Featuring PCIe 4.0 NVMe interface with dual-port connectivity, this drive enables active-active configurations in clustered and failover architectures without requiring external switching logic.

Designed for mixed-use workloads including transactional databases, virtualization, and high-frequency data access patterns, the SN840 combines enterprise-grade NAND flash with advanced error correction and power-loss protection. The 3.84TB capacity delivers substantial storage density for consolidation scenarios while maintaining consistent sub-millisecond latency profiles across sustained sequential and random I/O operations.

This model represents a significant advancement in dual-port NVMe adoption for mission-critical servers, providing the redundancy and accessibility patterns traditionally associated with SAS SSDs within the performance envelope of modern NVMe technology.

Ideal for

• Clustered database servers requiring shared storage with active-active failover
• High-availability virtualization infrastructures with live migration requirements
• Mission-critical transactional systems demanding dual-port redundancy
• Storage area network (SAN) nodes with concurrent multi-host access
• Enterprise application servers requiring sub-millisecond response times
• Real-time analytics platforms with persistent, high-concurrency workloads
