Quality, reliability and security
Ultrastar DC SN840 is built on Western Digital's 96-layer 3D TLC NAND, with high capacities in a U.2 2.5" form factor. It offers two endurance classes for workloads; 1 DW/D for read intensive workloads common with the majority of enterprise applications and cloud services, and 3 DW/D for higher write or mixed use workloads such as running SQL.
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 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 (Al), 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 3470/3330 MB/s sequential read/write and up to 503K IOPS mixed random 70/30 read/write performance.
