Move demanding workloads onto a faster wired path with this dual-port 10GbE NIC from StarTech. The PR210B-NETWORK-CARD adds two RJ45 10GBase-T ports through one PCI Express slot, giving you up to 20 Gbps of aggregate bandwidth for storage access, virtualization, and high-throughput file transfers. It is built on the Broadcom BCM57416 chipset and supports Gigabit Ethernet fallback for mixed-speed environments. This card is a practical fit for infrastructure teams that need more throughput without changing switch architecture. RJ45 connectivity keeps deployment straightforward in copper-based networks, while IEEE 802.3, 802.3u, and 802.3ab compliance supports broad interoperability. The included full-height and low-profile bracket options make it easier to standardize across tower systems and rack-mounted servers. For environments where network bottlenecks affect backup windows, VM density, or large dataset movement, this adapter provides a clean upgrade path. It is the kind of component that earns its place in a production build: simple to install, easy to integrate, and specified for sustained 10GbE performance where it matters.
