Ultrastar NVMe Series

Low Latency and Maximum Throughput for High-Transaction Workloads


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 drive, Ultrastar DC SN620, offers 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.

One megabyte (MB) is equal to one million bytes, one gigabyte (GB) is equal to 1,000MB (one billion bytes), and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to storage capacity. Accessible capacity will vary from the stated capacity due to formatting, system software, and other factors


Edurance rating based on DW/D using 4KiB random write workload over 5 years. 


Performance will vary by capacity point, or with the changes in useable capacity. Consult product manual for further details. All performance measurements are in full sustained mode and are peak values. Preliminary and subject to change. 1MiB=1,048,576 bytes or 220, 1KiB= 1,024 bytes or 210.


Average Write Latency at 4KiB QD=1. 


MTBF and AFR targets are based on a sample population and are estimated by statistical measurement and acceleration algorithms under median operating conditions. MTBF and AFR rating do not predict an individual drive’s reliability and do not constitute a warranty. 


The warranty for the product will expire on the earlier of (i) the date when the flash media has reached one-percent (1%) of its remaining life or (ii) the expiration of the time period associated with the Product. 


Edurance rating based on DW/D using JESD-219 workload over 5 years


Average Write Latency at 4KiB QD=32.
