Ultrastar NVMe Enterprise SSDs are the ideal solution for cloud and server providers that require powerful, cost-optimized read performance with high capacity for their data-intensive applications.
Unlocking 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 that your data is secure and available when needed. With high capacity and low latency performance reaching up to 1.1 million IOPS, storage providers can efficiently increase capacity for modern applications that process large unstructured datasets, reduce time to insight from big data, and enable efficient machine learning.
Features
The Ultrastar DC SN655 NVMe SSDs feature the next-generation Western Digital NVMe 1.4b controller with a PCIe Generation 4.0 interface and Western Digital BiCS5 TLC 3D NAND, allowing for higher capacities and performance while scaling for ever-larger application workloads. The SN655 is designed for standard 2.5-inch SSD storage infrastructure and supports U.2 and U.3 backplanes, as well as offering power loss protection, 2.5 million MTBF (projected), and 1.0 DW/D.
Emerging Workloads
Ultrastar DC SN65x NVMe SSDs are optimized for cloud and scale-out workloads, providing high QoS consistency for emerging workloads in big data, artificial intelligence, and machine learning that are increasing in size and complexity, making them the ideal solution for scaling capacity and maximizing GB/Watt.
