Secondly - as a person living my whole life in IT - both passion and professionally - I have no idea what would 25Gbit be good for. I’m currently paying about $80 for symmetrical 1Gbit fiber and have the option to upgrade to 5Gbit for about $180 but it seems so pointless.
Here is the reasoning behind my grumpy opinion:
1. Living in a home with Cat5 throughout so the best I can do is to route 1Gbit. Running cables in multilevel (American) homes is a major PITA.
2. My Wi-Fi (802.11ax) is heavily affected by homes around me so only one AP can run with 80MHz channel width and the rest is 20-40MHz. Throughput ends up being somewhere between 150Mbit-500Mbit, depending on where you are.
3. I have a few smaller servers running ..stuff. The trouble is not about server performance or bandwidth.. it’s about reliability. Running any business on consumer line (in the USA) is just signing up for trouble. (Eg. “Is your line down because your modem received a fault firmware? No worries, the tech is going to be there within next 4 days to check your cables…”).
4. Things like game downloads on PS5 .. yes, they are amazingly fast (even on 1Gbit. They install faster from internet than from the built-in BD-ROM). But many games need to also “install” (whatever that means on PS5) and that takes 2x the time of download anyway. I can live with that once a month.
5. Big fan of streaming services, however many providers limit bitrate on their side so I am still watching the sometimes blurry 4k …
Back to original question and with genuine curiosity - what is 25Gbit for???
