Upgrade copper-based infrastructure to 10GbE without replacing the cabling plant. The StarTech ST10GSPEXNDP2 is a dual-port PCIe network adapter built for desktops, servers, and small form factor systems that need higher wired throughput on existing RJ45 infrastructure. With support for 10GBASE-T and NBASE-T, it gives IT teams a practical path to faster access for storage, virtualization, media workflows, and dense client-server traffic. The adapter uses a PCIe 3.0 x4 host interface and Marvell AQC113CS silicon, pairing modern network capability with broad deployment flexibility. It supports Cat5e, Cat6, and Cat6a cabling, which helps reduce upgrade cost when the network layer is already in place. Features such as VLAN support, PXE boot, 16K jumbo frames, AVB, and PTP make it suitable for environments that care about provisioning, segmentation, and timing-sensitive traffic. For procurement teams, this card earns its price by extending the life of existing copper runs while delivering a meaningful step up in bandwidth. For infrastructure teams, it is a straightforward way to add 10GbE to compatible Windows, Windows Server, and Linux systems without moving to fiber or redesigning the rack.
