10 gigabits per second network connection
10 gigabits per second network connection
Because you're sending data across long distances, the connection speed will be much lower. Pick a faster local test and you'll get better results. Unless your network supports speeds above 1 gbps for wide area connections or you handle large internal transfers, the cost of the gear isn't justified.
There is one possibility where it could benefit going higher than 1Gbit, if somehow you managed to download at 1Gbit and wanted to copy files to/from another PC on the LAN, at the same time. A pretty unlikely scenario though for most people. I upgraded because I do plan to get Gigabit FTTP once it launches here and I didn't want to bottleneck downloads on my server/NAS while I was also moving files to/from that machine to other PCs on the network. You don't necessarily need to upgrade the modem/router though, just have a multi-gig switch you plug the PCs into with one port of that going to the router.
The NAS uses Ironwolf drives capable of 200MB/s, which already limits performance. Additionally, you'd lose around 300KB per second due to acknowledgments, and even with modern HDDs, speeds would remain well below a gigabit. Whether it's worth the investment depends entirely on your specific needs. For my case it was, but others should evaluate their requirements first.
