Ha! Been running these for years on both linux and windows (on lenovo x1 laptops). Using cheap chinese thunderbolt-to-nvme adapters + nvme-to-pcie boards + mellanox cx4 cards (recently got one cx5 and a solarflare x2).

10gig can saturate full speed, 25G in my experience rarely reaches same 20G as the author observed.

If you don’t mind me asking, what are you using these for? Saturating these seems like it would have reasonably few workloads outside of like cdn or multi-tenant scenarios. Curious what my lack of imagination is hiding here.

Officially: to access NAS, get raw market-data files (tens to hundreds of gigabytes a day), not needed on laptop every day, but only once in a while to fix or analyze something.

Really: because I can, and it is fun. I upgraded my home lan to 10G, because used 10G hardware is cheap (and now 25G enters the same price range).

I do media production, and sometimes move giant files (like ggufs) around my network, so 25 Gbps is more useful than 10 Gbps, if it's no too expensive.
