AI-generated summary
At £240 ex-VAT for a 2‑port SFP28 internal card, this is a pretty decent “boring” upgrade if you’ve already got (or plan to use) short-reach optics and a switch that speaks 25GbE. The main value here is sanity: it’s Lenovo-branded hardware that’s typically easier to drop into Lenovo servers without the usual “will this firmware play nicely?” theatre. If you’re building a small server-based storage/virtualisation setup and want clean, predictable connectivity, this kind of dual-port 25GbE NIC tends to do the job without drama.
That said, I wouldn’t buy it blind. First, confirm your host actually supports the right PCIe generation/lanes and that you’re not accidentally expecting more than it can deliver in your specific server backplane layout. Second, SFP28 means you need the matching 10/25GbE transceivers and switch ports—so if your infrastructure is mostly 10GbE, this may be wasted spend unless you’re upgrading optics and switching alongside it. For anyone running a budget-limited environment or uncertain about compatibility, you’ll usually get better overall value by buying a known-compatible option for your exact server model (or by standardising on a single NIC/transceiver ecosystem across the site).
