Overview

Editorial opinion

Best for: A small 10 GbE backbone: NAS, Proxmox nodes and an uplink, with DAC cables.

Editorial opinionWould we buy it today?

Yes with DAC or fibre; if your devices have RJ45 10 GbE, take the CRS304.

Pros and cons

Editorial opinion

Pros

  • 4 × SFP+ for $149
  • Fanless metal case
  • VLANs and LACP

Cons

  • SFP+ only: modules or DAC cables needed
  • 10GBASE-T modules overheat in it

Good to know

10 W without modules and 18 W with them, per MikroTik. Use DAC or fibre modules: RJ45 10G modules run hot.
