Product information

Description

The Western Digital Ultrastar DC SN655 30.7 TB U.3 NVMe SSD is a high-capacity, enterprise-grade drive designed for cloud, server and scale-out storage environments. Built on PCIe 4.0 and Western Digital BiCS5 TLC 3D NAND, the SN655 delivers low-latency, read-intensive performance and dual-port redundancy for continuous availability. It supports standard 2.5" infrastructure with U.2 and U.3 backplane compatibility and includes power-loss protection and a 5-year limited warranty.

Advantages

The Ultrastar DC SN655 combines high capacity and high IOPS with PCIe Gen4 performance and enterprise features such as dual-port failover, end-to-end data protection and power-loss protection. Its 30.7 TB capacity and modern controller architecture enable efficient handling of large unstructured datasets while maintaining QoS consistency for demanding cloud and AI workloads. The drive is designed for compatibility with existing 2.5" U.2/U.3 backplanes and provides a projected MTBF of 2.5M hours.

Suitable for

Cloud storage and hyperscale server deployments
Big data processing and analytics
Machine learning and artificial intelligence training/inference
High-density scale-out storage systems

How to use

Install the SN655 into a compatible U.3 or U.2 slot on a server or storage chassis that supports PCIe 4.0 NVMe drives. Ensure the host firmware and operating system NVMe drivers support NVMe 1.4b and that backplane wiring supports dual-port functionality if used. After physical installation, initialize and format the drive in your OS or storage controller according to your deployment plan, configure RAID or software-defined storage as needed, and verify that power-loss protection and SMART attributes are reported correctly.

Usage recommendations

For read-intensive, large-scale workloads such as analytics, AI and large object datasets, use the Ultrastar DC SN655 to scale capacity while maintaining QoS. Pair with servers and controllers that fully support PCIe Gen4 and U.3 backplanes, monitor SMART metrics and firmware updates from Western Digital, and design redundancy (dual-port or cluster-level) to ensure availability for mission-critical data.
