Data strategy, not just data storage
Ultrastar NVMe™ Enterprise SSDs continue to be the ideal solution for cloud and server providers who need high-performance, cost-optimised, high-capacity read performance for their data-intensive applications.

Unleashing the full potential of Enterprise SSDs
With dual-port redundancy and failover capability, end-to-end data protection and additional enterprise features, Ultrastar DC SN655 NVMe SSDs help ensure your data is secure and available when you need it. With high capacity and low latency performance reaching up to 1.1M IOPs, storage providers are able to efficiently increase capacity for modern applications that process large unstructured data sets, reduce time to big data analysis and enable efficient machine learning.

Features
The Ultrastar DC SN655 NVMe SSDs incorporate the next-generation Western Digital NVMe 1.4b controller with PCIe Generation 4.0 interface and Western Digital BiCS5 TLC 3D NAND to enable higher capacity and performance at scale for ever-increasing application workloads. Designed for standard 2.5-inch SSD storage infrastructure, the SN655 offers support for U.2 and U.3 backplanes and offers power loss protection as well as 2.5M MTBF (projected) and 1.0 DW/D.

Emerging workloads
Ultrastar DC SN65x NVMe SSDs are optimised for cloud and scale-out workloads and provide high QoS consistency for the emerging workloads for big data, artificial intelligence and machine learning that are increasing in size and complexity, making them the ideal solution for scaling capacity and maximising GB/Watt.
