QNAP QXG-25G2SF-E810

Overview

The QNAP QXG-25G2SF-E810 is a two-port 25 GbE network adapter designed to fit into a PCIe 4.0 x8 slot on desktop workstations or compatible QNAP NAS devices. Each SFP28 port supports data transfer speeds up to 25 Gb per second, providing the bandwidth needed for demanding tasks such as 4K and 8K video editing, virtualization, and large backup replication. When both ports are combined using SMB multichannel or port trunking, the card can deliver an aggregated throughput of up to 50 Gb per second, significantly reducing data transfer times.

Key features

• Two 25 GbE SFP28 ports that enable fast and efficient large data transfers
• PCIe 4.0 x8 interface ensures sufficient bandwidth to handle high-speed network traffic without bottlenecks
• Port trunking support allows combining both ports for up to 50 Gb per second aggregated throughput, ideal for heavy workloads
• Forward Error Correction technology maintains signal integrity, ensuring reliable data delivery during sustained transfers
• Compatible with multiple operating systems including QNAP QTS, QuTS hero, Windows, and Linux for versatile deployment
• Includes low-profile, full-height, and NAS-specific brackets for flexible installation in various chassis types

Key specs

• Network ports: 2 x 25 GbE SFP28
• Interface: PCIe 4.0 x8
• Maximum aggregated throughput: 50 Gb per second (with port trunking)
• Supported operating systems: QTS, QuTS hero, Windows, Linux
• Installation brackets: low-profile, full-height, NAS-specific

Connectivity and compatibility

This network adapter supports direct connection to 25 GbE switches or direct-attach cables, making it suitable for high-speed networking environments. Its compatibility with QNAP NAS operating systems as well as Windows and Linux ensures it can be integrated into a variety of setups, from professional studios to enterprise IT infrastructures.

Installation and setup

Installation is straightforward: simply insert the card into a free PCIe 4.0 x8 slot and select the appropriate bracket for your system chassis. After loading the necessary drivers, the adapter is ready to deliver high-speed network connectivity. This ease of setup helps minimize downtime and accelerates deployment in busy work environments.

Ideal uses and environments

This adapter is well suited for creative teams working with high-resolution video files, IT professionals managing virtualized hosts, and businesses performing large-scale backup replication. By upgrading to 25 GbE speeds, users can offload traffic from existing 10 GbE or 1 GbE connections, freeing those for other tasks and shortening data transfer windows in demanding workflows.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
