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

Realise the full potential of enterprise SSDs
With dual-port redundancy and failover functionality, 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, low-latency performance of up to 1.1 million IOPS, storage providers can efficiently increase capacity for modern applications that process large unstructured data sets, reduce time-to-insight for 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 PCIe Generation 4.0 interface and Western Digital BiCS5 TLC 3D NAND to enable higher capacity and performance at scale for increasingly large application workloads. Designed and built for the standard 2.5-inch SSD storage infrastructure, the SN655 supports U.2 and U.3 backplanes and offers power failure protection and an MTBF of 2.5 million hours (projected) and 1.0 DW/D.

Emerging workloads
