This PCIe network card makes it easy to add two 10GBase-T ports to your server or workstation, providing an affordable solution for high-bandwidth applications. It supports 10GbE over Cat 6 cabling up to 55 meters and Cat 6A cabling up to 100 meters. Compatible with a broad range of operating systems, this versatile dual-port NIC reduces network slowdown/degradation when running data-intensive applications/processes such as FTPs and online storage/backup. It's a cost-effective way to enhance your server or computer capabilities by adding two powerful 10-Gigabit Ethernet ports, with support for advanced features such as VLAN tagging, jumbo frames, and Auto-MDIX. This 2-port PCI Express 10GBase-T network card features the Broadcom BCM57416 chipset, designed to deliver the power, performance and enhanced capabilities you need for reliable network connections to your server or computer. Compliant with IEEE 802.1Q standards, this network card offers an efficient way to upgrade or replace your existing network ports with dual 1G/10G-compatible RJ45 ports, delivering up to 10Gbps of throughput per port in each direction (20Gbps total). It connects through a single, four-lane (x8 or higher) PCI Express slot. With a dual-profile design, the PCI Express network card installs easily into a wide range of computer/server chassis, regardless of form factor. The card comes equipped for installation in a full-sized chassis and includes a low-profile/half-height installation bracket that you can use as needed.

The StarTech PR210B-NETWORK-CARD is a dual-port PCIe 10GbE network card with RJ45 ports and a Broadcom BCM57416 chipset, suited to server and workstation users who need two high-speed wired connections for data-intensive transfers, storage, or cloud workloads.
Recommended For
- Desktop or server users moving large files to a 10GbE NAS or storage server over existing RJ45 cabling; the card adds two copper 10GbE ports for storage and backup traffic.
- Server and workstation operators who need two wired 10GbE connections for separate networks, such as storage and production traffic, or for supported link aggregation and failover setups.
- Virtualization, lab, or on-prem server builders who have an available PCIe x8-or-higher slot and want a dual-port RJ45 adapter with VLAN tagging and jumbo-frame support.
- Organizations upgrading a wired PC or server on a 1GbE network that are moving to 10GbE but still need the ports to negotiate with 1GbE equipment.
Real-World Use Scenarios
- A workstation moves large project files to or from a 10GbE NAS over a wired network; transfers can take less time than over 1GbE when the NAS, storage, and network path can keep up.
- A server handles network backups or FTP transfers to shared storage; the 10GbE connection can reduce network bottlenecks during large or frequent data moves, provided the storage and other devices support similar throughput.
- A virtualization host connects to storage or other servers on a high-traffic network; the extra Ethernet capacity can help keep virtual-machine and storage traffic from competing as heavily for a 1GbE link.
- An IT administrator uses the two ports for separate networks, such as keeping tagged VLAN traffic or a storage network apart from general server traffic; each connection can be managed independently in the network setup.
- A server needs a teamed connection for added link resilience or aggregate bandwidth; the card supports 802.3ad, but the connected switch and server configuration must also support and be configured for link aggregation.
- A business adds 10GbE to a server while retaining some 1GbE equipment; the ports can negotiate a 1GbE link with compatible devices, allowing a gradual network upgrade rather than requiring every connected device to change at once.
