This will be a series of posts. I upgraded my NAS to a model with dual 10G ports, and the compute server already had 10G so I had an excuse.

Old setup – 4-bay Synology DS416play and a USB3 drive caddy for a temporary backup solution. TP-Link 16 port switch, all ports in use.

After some searching, I found this Mikrotik switch for $142 on Amazon. 28 ports of 1G plus two 10G ports. Most switches with 10g are either $100 per port or have fans – this one is 19 watts, no fans, and cheap. Note the “sfp+” notation – it means you need more pricy bits to finish the job, but you can use other media like fiber optic links. So total cost of almost 2x.
Switch in and waiting for NAS backup to complete:

Power usage went down by 20 or 30 watts. Always something I pay close attention to. Here’s semi-final:

Next week I get the SFP+ transceivers and rewire a bit. Trunked dual 1G links for now. Power usage is back to where it was, maybe down a watt or two. The new switch is only 19W (the old was around 30) but the larger NAS uses more power, so even under heavy load with 5 disks going.
