The Dynamic Data Center Environment

IT organizations have to optimize their infrastructure for the dynamic data center environment by improving utilization of storage capacity for demanding new workloads, improving responsiveness for critical applications, maintaining uptimes and availability, and lowering their TCO. With the advent cloud architectures driving new on premise data center designs utilizing converged, hyper converged, and composable infrastructure with higher performance CPUs, traditional SATA-based storage have become the bottleneck. Whereas, NVMe-based SSDs are designed specifically to maximize performance of flash memory and are widely deployed in the public cloud offering flexibility and scalability at lower costs.

The new Ultrastar DC SN640 NVMe SSD improves performance and responsiveness over the current generation DC SN630 NVMe SSD and offers capacities including 960GB, 1.92TB, 3.84TB, and 7.68TB in U.2. (Gen3.1 x 4). The SN640 includes Western Digital’s industry-leading 96L BiCS4 3D TLC NAND and in-house NVMe 1.3 controller providing 5x read performance improvement over SATA SSDs. The DC SN640 is a cost-optimized NVMe SSDs for broad deployment into cloud/hyperscale and on-prem data centers. The SN640 includes enterprise reliability features including power-loss protection, end-to-end data path protection, and a 5-year limited warranty.

Designed for Workload Flexibility

The DC SN640 is offered in two endurance classes: 0.80 DW/D and 2 DW/D, each for a period of five years. The 0.80 DW/D swim lane is designed for read intensive applications while the 2 DW/D swim lane can be deployed in mixed-use workloads requiring higher performance and endurance levels over the life of the drive providing IT organizations a way to optimize for application performance.

Safeguarding Data

Regulatory and privacy requirements demand the need for increased data security for data at rest. The Ultrastar DC SN640 with Instant Secure Erase (ISE) helps safeguard data with AES-256 encryption engine and provides instant erase upon decommissioning and recommissioning the drive. Secured Firmware downloads with RSA authentication ensure that the drive runs authentic Western Digital firmware only.
