Analysts predict that in the next few years, many IT companies and corporate data centers will abandon the use of outdated SATA and SAS interfaces in search of more relevant solutions. Therefore, WD Ultrastar drives strive to be ahead of the times and give all the necessary tools to data centre owners today. Like no other, these models are suitable for round-the-clock operation, constant access to data, recording and delivery of data.


A feature of the Ultrastar series was the use of dual-port NVMe drives, which are based on Rap idFlex controllers, support the new OpenFlex Data24 storage platform and the NVMe-oF format. They allow multiple Ultrastar drives to form a so-called disk shelf and directly connect up to six hosts to it using a regular Ethernet cable without the need for an external switch.

Given the narrow specificity and experimental format, only a few drives were presented in the Ultrastar series, the first of which was the Ultrastar DC SN840. This third-generation WD server solution is based on 96-layer 3D TLC NAND memory, with a vertically integrated NVMe controller and impressive uptime. It delivers competitive performance up to 780K/250K IOPS, 3470MB/s read line speed and impressive maximum capacity. According to the company's experts, such a drive will allow corporate clients to seamlessly switch from outdated SATA and SAS solutions to a more up-to-date NVMe platform.
