Not just data storage – a data strategy
The Ultrastar DC SN650 SSD is a mainstream NVMe™ SSD for a wide range of applications in data centres and cloud environments.

NVMe SSD with large storage capacity and disaggregated storage architecture
Disaggregated storage is ideal for cloud service providers. It supports a variety of storage services that together enable higher quality of service, consistent performance and better storage utilisation.

Disaggregated storage offers managed service providers an efficient approach to increase capacity for customers in scale-out data centres for applications that process large unstructured data sets.

As workloads continue to grow to petabyte sizes, cost-optimised high-capacity SSDs are playing an increasingly important role. The Ultrastar DC SN650 NVMe SSD can shorten the time to insight.

For the workloads of the future
The Ultrastar DC SN650 NVMe SSD is optimised for cloud and scale-out workloads, providing higher QoS consistency and better storage utilisation for block, object or file storage.

Big data, artificial intelligence and machine learning workloads are growing in size and complexity. The Ultrastar DC SN650 NVMe SSD is optimised to move large datasets quickly and serve multiple hosts with consistent performance. This makes it ideal for capacity scaling and GB/watt maximisation for these new, larger workloads.

PCIe Gen 4.0
The Ultrastar DC SN650 supports the latest PCIe generation 4.0 and offers scalable performance for growing application workloads. It is designed for standard 2.5-inch SSD storage infrastructure and supports U.2 and U.3 backplanes.

Data protection
The Ultrastar DC SN650 NVMe SSD ensures that you will not lose your data in the event of a power failure. The SSD has a power failure protection that protects your data in the event of a sudden and unexpected interruption to the power supply. And if you ever need to take the SSD out of service, the Secure Erase function allows you to erase the entire drive.

Reliability
The Ultrastar DC SN650 NVMe SSD is designed for reliability with enterprise features such as power failure protection, 2 million hours MTBF (expected) and 1 DW/D2.
