Ultrastar NVMe Series

Low Latency and Maximum Throughput for High-Transaction Workloads

OVERVIEW

Accelerate Access to Critical Data for Data-Intensive Workloads and Applications

Ultrastar NVMe series SSDs perform at the speed of today's business needs. Enabling faster intelligence and access to critical data, these SSDs meet the growing digital demands of your business applications. Our top-end Ultrastar DC SN200 drive delivers extreme performance and ultra-low latency to the top tier of enterprise storage. It takes hyper-converged infrastructure (HCI) system throughput to new levels and helps scale on-line transaction processing (OLTP). Our Essential NVMe drives, Ultrastar DC SN620 and DC SN630, offer low latency and higher bandwidth for a seamless transition away from SATA SSDs in mixed-use and read-intensive applications. This combination of high throughput and predictable low latency delivers high performance for deeper insights and faster results for today's data intensive applications.
