The TrueNAS Mini R ships with both 10GbE and 1GbE onboard

TrueNAS doesn’t skimp on the Mini R’s networking: two 10 Gigabit Ethernet ports for the heavy lifting, plus two 1 Gigabit Ethernet ports for management or out-of-band access. It’s a rare configuration at this form factor — most compact NAS units top out at 2.5GbE or offer a single 10GbE port at best.
