Are LAN sockets still up-to-date? WLAN/wireless is the future!

I no longer find 10 Gbit so extraordinary. When I get a new NAS, it will also go in that direction. At the moment still internal network, but going outside it will also exceed 1 Gbit. With cable connections, for example, work is already being done on DOCSIS 4.0.

Then please tell me what you are doing there and show how much percent of the bandwidth you are also utilizing during your work.

Probably temporarily up to 100 percent, and that's what it's all about. That you can also surf/stream/email/Instagram/whatever with significantly less bandwidth is beyond question, but if I ever transfer larger amounts of data, then it should also be fast. That's why my NAS units are connected via QSFP+ and all desktops via SFP+. Logically, this also requires correspondingly high-performance hardware in the NAS to exploit this bandwidth.

Video editing, image processing for DTP, normal computer stuff. I never claimed to fully utilize the 10 GbE; the SSDs and hard drives in the NAS probably rarely manage that either. But I regularly operate in the range of 3-4 Gbit, which is significantly beyond the usual 1 GbE network.

Thanks for the statement I hope you don’t misunderstand me here, but for me those are bandwidths that are very high and not exactly cheap to implement. I always wonder what people are doing on their network when they think they need such high bandwidths. I can hardly imagine that several people are simultaneously doing, for example, video editing over LAN on a NAS or that 5-6 video streams are running at the same time. As I said, what you are doing is definitely cool.

Well, just making regular automated backups of entire computers (which wouldn’t be so unusual) can already be a practical thing. It’s purely a matter of calculation. If you do it regularly, then you don’t have the traffic on the network for so long. For example, I’ve wanted to set it up for a long time, but I’ve never taken the time so far.

It should also be obvious that the bandwidth of a server should tend to always be greater than that of the fastest client, otherwise the latter could completely saturate the server, and then everyone else is out of luck. Since there are not many alternatives above 10 Gb/s, it ended up being 40, and yes, you definitely don't have to have that and can still have fun, but it is also somewhat a hobby.
