Incredible 25GbE Connectivity

Many bandwidth-intensive workflows - including post-production shared storage workgroups - have reached a point where 10Gb Ethernet does not provide sufficient bandwidth and speed for optimum performance. Upgrading to 25Gb Ethernet is the smart choice - it offers greater performance and works with the same optical network infrastructure as 10GbE. Step up to the Sonnet Twin25G™ PCIe Card, an affordable and powerful solution for adding incredibly-fast fiber optic 25GbE network connectivity.

Fast Network Performance for Shared Storage Workgroups | Compatible with 10Gb Fibre Networks. Future Proof Support for 25Gb Networks | Compatible with Mac, Windows, and Linux Computers with PCIe Slots | Affordable 25GbE Networking Make the Switch

Mac users need faster network speeds and increased bandwidth for postproduction workflows. Recently, 25Gb Ethernet switches have become more affordable, but connecting a 2019 Mac Pro®to a 25GbE infrastructure has been expensive. Sonnet's Twin25G PCIe Card is a cost-effective and simple solution for adding 25GbE network connectivity to not only Mac Pro, but also to any computer with PCIe slots.
