Performance NVMe SSDs enable enterprise workloads. The adoption of NVMe in data centers continues to grow as modern applications and workloads demand more performance. The Western Digital Ultrastar DC SN840 Performance NVMe SSDs are designed for primary storage in HPC servers and primary storage in external storage arrays.

Performance NVMe SSDs target cloud computing and enterprise workloads that require low latency for data and high data availability. 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 third generation of high-performance NVMe SSDs for data centers, featuring PCIe Gen 3.1 (Dual-Port), NVMe 1.3, delivering up to 3,470/3,300 MB/s sequential read/write performance and up to 503K IOPS mixed random 70/30 read/write performance.

Dual-Port Leadership. The Ultrastar DC SN840 enhances Western Digital's leadership in dual-port architecture through vertical integration of proven flash controllers. Dual-port high availability supports two redundant paths to the SSD and is crucial for ensuring data access in the event of a data path failure.
