The TrueNAS Mini X+ connects via two 2.5GbE ports

The TrueNAS Mini X+ lands in the middle of the speed spectrum with two 2.5 Gigabit Ethernet ports — a nice step up from the 1GbE standard on budget NAS units, though below the 10GbE you get on the Mini R. For a home lab or small office, 2.5GbE is a sweet spot: faster than Gigabit without the heat or cost of 10GBASE-T.
