£139.12 inc. VAT
AI-generated summary
At £116 ex-VAT for a 2‑port PCIe 5G‑capable NIC, this StarTech card is mainly a “make it work reliably” purchase rather than a bargain-bin upgrade. The Realtek RTL8126 chipset is usually a safe bet for everyday performance and driver support on Windows and Linux, which matters in UK business environments where you don’t want to spend your week chasing edge-case networking drivers. The 2‑port setup is handy for servers, lab PCs, small virtualization hosts, or any box that needs a dedicated management/network path without juggling USB or swapping cables.
Who should buy it: teams that want straightforward 2.5/5GbE connectivity in a desktop/server form factor, with decent compatibility, and don’t need exotic features. Who might pass: if you’re building something where you demand rock-solid enterprise features (advanced teaming, very specific offload behavior, or vendor-specific management tooling), you might find cheaper 2.5GbE Realtek cards just as good—or find a more fully “enterprise” NIC package costs more for a reason. Also, double-check your server/workstation has the right PCIe slot and lane availability; a lot of people assume “PCIe is PCIe” and then wonder why performance doesn’t match expectations.
