Intel is overpriced and still riding their Ethernet reputation from well over a decade ago with little to show for it. I would recommend cxgbe anything, so Chelsio T420 and up. The T520-SO-CR is within reason for demanding home office/small office users to purchase new and I've deployed over a thousand of these at work with flawless performance. T420 are a bit cheaper on i.e. US ebay if that is viable to you but not by too much. I bought a T420-BT that way for home use and have no complaints. For non-TOE use at 10g, the difference between T4 and T5 doesn't matter too much, pcie 2.0 vs 3.0. You can use DAC twinax cables to connect 10G SFP+ ports together. This will save several watts of power and heat on each side vs 10G Base-T. Sometimes DACs have interop problems, usually with switches. Optics are more forgiving, although again the switch side may have extra hoops like approved vendors. As far as a switch, I got a good deal on the beta UniFi version of https://www.ubnt.com/edgemax/edgeswitch-16-xg/ for my home network. Now that it is full price, I would recommend the EdgeMax version unless you have other UniFi gear. They are inexpensive as far as the physical connectivity versus the rest of the market but not quite cheap yet. These aren't exactly pro grade, the interop seems pretty poor in general, but that's the price you pay for the price you didn't pay :) Regards, On Sun, Jan 15, 2017 at 2:32 AM, Lev Serebryakov <lev@freebsd.org> wrote: > Hello Freebsd-net, > > I want to attach my DIY-NAS (FreeBSD-based) to my desktop (Windows-based) > with 10Gb link.
