SSD - Ultrastar DC SN840 - 1920GB - Pci-e Gen 3.1 x4 - U.2 2.5in - SE 1 DW/D

Introduction

Performance NVMe™ SSDs Enable Enterprise Workloads

NVMe™ adoption in the data center continues to grow as modern applications and workloads demand more performance. Performance NVMe SSDs are designed for primary storage for HPC servers and primary storage in external storage arrays.

Performance NVMe™ SSDs Enable Enterprise Workloads
Performance NVMe SSDs target cloud compute and enterprise workloads that require low latency to data and high availability of data. These applications include real-time data analytics, cloud computing, OLTP/OLAP databases, artificial intelligence (AI), machine learning (ML), pattern recognition and virtualization. The Ultrastar DC SN840 is Western Digital’s 3rd generation of performance NVMe SSD for data center with PCIe Gen 3.1 (dual-port), NVMe 1.3, providing up to 3,470/3,300 MB/s Sequential Read/Write and up to 503K IOPS mixed random 70/30 read/write performance.

Dual-port Leadership
Ultrastar DC SN840 extends Western Digital’s leadership in dual-port architecture by vertically integrating proven flash controllers. 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.
