MikroTik CRS305 vs MikroTik CRS304

Our verdict

Editorial opinionOur verdict

Same idea, four 10 GbE ports with RouterOS, different connectors. The CRS305 has SFP+ cages: cheap and cool with DAC cables or fibre. The CRS304 has RJ45: ordinary Cat6 cable and also 2.5/5 GbE, at more power. Match your network cards.
