| True, I don't really feel limited by my existing 500Mbps down, but knowing I'll be having 2500Mbps up/down soon means I want to have the infra to handle it. Basing things on 2.5GbE would certainly have been cheaper but some things don't support it (they either do 1GbE or 10G SFP+) so settling on 10G where possible made more sense to me. My future ISP also has a 5Gbps up/down option, but even I can't justify that right now. My wife and kid just want their phones/laptops to work, and to be able to stream stuff to watch, they don't care about the underlying speed. Having a faster network may make some of my work related things run a bit quicker. A few times a day I'll need to pull something big down (either an ISO or a bunch of docker images) and that can take up to 2 minutes with 500Mbps down. Having those take a fifth of that time will make it seem less of a roadblock to doing work. 2 minutes meant I went and got a cup of coffee and often got more distracted, 30 seconds should keep me at my desk and focused on what I was doing. That's not a big enough reason to justify it on its own obviously. I also want to do offsite backups with/for various family members, so something better than 75Mbps up is going to be a huge boost. Getting 1Gbps+ out will be huge (assuming whatever is at the other end can support that). I don't do any kind of data hoarding, I think I've got something under 4TB of data that I actually care about, and most of that are family photos/videos. Deep down it's mostly because I'm a networking geek so it's fun to play with some new kit and make blinkenlights. |
One thing to remember is 2.5 gbit/sec uplink is shared between all clients. So if one client is on 1 gbit, and one client could saturate their 1 gbit while switch and router can handle better. An advantage of that is QoS isn't needed to be applied manually.
So, for example, it maybe worth it to have higher than 1 gbit uplink on switch to router, and maybe a server to switch, but devices such as your TV or WLAN clients do not need such.
75 mbit up is pretty good compared to DSL (I bet it is cable), and yes 1 gbit up is nice for off-site backups. But the upsell of going above 1 gbit symmetric IMO isn't there.
Cable providers know this. Which is why they sit below 1 gbit symmetric, at a level average subscribers are comfortable with.
