Ultrastar DC SN630

Ultrastar® NVMe Series

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 & access to critical data, these SSDs meet the growing digital demands of your business applications. Ultrastar DC SN200 delivers extreme performance & ultra-low latency to the top tier of enterprise storage. It takes hyper-converged infrastructure (HCI) system throughput to new levels & helps scale on-line transaction processing (OLTP). Our Essential NVMe drives, Ultrastar

DC SN640 & DC SN630, offer low latency & higher bandwidth for a seamless transition away from SATA SSDs in mixed-use & read-intensive applications. This high throughput & low latency delivers high performance for deeper insights & faster results for today’s data intensive applications. Ultrastar DC SN340 provides a power efficient cost-optimized solution for very read⁠-⁠intensive applications & warm storage.
