Features:

The Dynamic Data Center Environment
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.

Mainstream NVMe SSD for Data Center IT and Cloud Deployment
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. The DC SN640 is optimized to deliver the highest performance and consistent QoS read latency when running random mixed workloads typically generated by enterprise applications such as virtualization, OLTP, NoSQL, web servers, file servers, and mail servers.

The DC SN640 NVMe SSD is ideal for replacing SATA SSDs by delivering 6x improvement in sequential read performance and 3x improvement random mixed read/write performance. The DC SN640 boosts data center performance and responsiveness as direct attached, distributed storage or in large scale cloud deployments.

The DC SN640 includes Western Digitals 96-Layer BiCS4 3D TLC NAND and Western Digitals NVMe 1.3 controller and incorporates enterprise reliability features, such as power-loss protection, end-to-end data path protection.

Designed for Workload Flexibility
The Ultrastar DC SN640 is available in two endurance classes: 0.8 DW/D2 (capacities from 960GB-7.68TB)1 and 2 DW/D2 (capacities 800GB-6.4TB). The 0.8 DW/D SKU features tunable endurance, giving customers the flexibility to configure endurance and performance for seasonal burst workloads.
