Western Digital Ultrastar DC SN655 7.68TB U.3 NVMe SSD

The Western Digital Ultrastar DC SN655 is an enterprise-grade NVMe SSD purpose-built for zone namespace (ZNS) storage architectures in distributed and object storage systems. With 7.68TB capacity and U.3 form factor, the SN655 delivers sequential read/write performance optimized for high-throughput workloads while reducing write amplification through native ZNS support, enabling more efficient capacity utilization in large-scale deployments.

Designed for hyperscale edge infrastructure and telecom environments, the SN655 features a PCIe 5.0 interface and is engineered to handle sustained workloads with consistent performance. The drive's architecture prioritizes reliability and efficiency in 24/7 operational scenarios typical of cloud-native and distributed storage systems.

Launched in Q4 2022, the SN655 has achieved significant adoption among hyperscale operators deploying ZNS-optimized storage clusters, demonstrating strong market traction in next-generation data center infrastructure segments.
