I just got my 1 gbps fiber for my huge server. I found that with 125 MB/s network’s capacity, you hit hardware limitations very quickly, HDD in particular. Before going beyond 1 gig, you should ask yourself if you really need more, as you will need to upgrade everything to high specs, from hard drives, cards, cables, router, vpn, to finally notice your network stays close to 5 % usage most of the time, and that the 8Gbps advertised are only reached using a speed test, only at 4 in the morning, and that your expensive upgrade is in reality barely used.

A good router is expensive, a good network card with a good transceiver is expensive, and you need to have many, 8Gbps is CPU hungry, SSDs are wearing fast, it’s electric power hungry. This speed comes with a huge investment and heavy running costs.

I will stick with 1 gig for quite sometime I guess, it’s far enough for my heavy usage, I can’t imagine being too restricted to invest hundreds, if not a couple of thousands.

Truenas is completely unnecessary, it just brings overhead and complexity. You are good with your setup.
