The new Ultrastar SSDs deliver on quality, reliability and security features. Ultrastar NVMe SSDs give enterprise reliability for excellent QoS, a limited 5-year warranty and security options including TCG Ruby and FIPS 140-2 validation.

Ultrastar DC SN840, the Performance NVMe

The Ultrastar DC SN840 with high performance and dual-port high availability is designed for demanding platforms such as HPC, real-time analytics, cloud computing, OLTP/OLAP databases, and AI and machine learning.

Low-latency, performance NVMe SSDs are ideal for demanding platforms:

• High Performance Computing (HPC) servers
• mission-critical applications
• high-availability storage arrays that require dual-port controllers for fault-tolerant conditions

Ultrastar DC SN840 NVMe SSDs deliver extreme performance and ultra-low latency to the top tier of enterprise storage with:

• Dual Port NVM-PCIe Controller for high availability
• Optimizer for consistent high performance and low latency on mixed random workloads
• Up to 15.36TB in a U.2 15mm form factor
• 1 and 3 DW/D for read-intensive workloads and higher write or mixed use workloads
• Enterprise features including end to end data path protection, power loss protection, and security options: SE, ISE, TCG Ruby, and FPIS 140-2 validation (forthcoming)

NVMe SSDs Benefit a Range of Applications

Real-time analytics, cloud computing, OLTP/OLAP databases, artificial intelligence (AI), machine learning (ML), pattern recognition and virtualization can all benefit from utilizing performance NVMe SSDs.

Dual-port Leadership

Dual-port high availability supports two redundant paths to the SSD and is critical to ensuring access to data in the event of a failure in the data path.

Quality, Reliability and Security

The Ultrastar DC SN840 delivers enterprise reliability MTBF of 2.5M hours (projected), a limited 5-year warranty, and security options of Secure Erase (SE), Instant Secure Erase (ISE), TCG Ruby and FPIS 140-2 validation (forthcoming).

Ultrastar DC SN640, the Mainstream NVMe

The Ultrastar DC SN640 NVMe SSD is a mainstream NVMe SSD targeting broad deployment as boot, caching, or primary storage in data center IT and cloud environments. With up to 6x the read speeds over SATA SSDs plus low latency, the Ultrastar DC SN640 is the perfect solution to lower your data center TCO.

Ultrastar DC SN640 SSDs are optimized for consistent quality of service and low latency for mixed random read/write workloads commonly generated by top enterprise applications such as virtualization, OLTP, NoSQL, web servers, file servers and mail servers. Ultrastar DC SN640 enables a seamless transition from SATA SSDs, delivering high performance for deeper insights & faster results for today’s data intensive applications.
