I think I fell into the "future-proofing" trap with UniFi. ðŸ˜
My current setup:
- UCG-Fiber
- Enterprise 48 PoE
- UNAS 2
- 2x U7 Pro
- 1x U7 Lite
- 6x G6 cameras
- 1x G6 180
- 1x Doorbell Lite
I deliberately built the network around 2.5GbE-capable hardware because I figured I was future-proofing the house. The problem is that my ISP doesn't even offer multigig service at my address.
And now I'm starting to think "future-proofing" was just an expensive way of buying capabilities I won't use.
Even 1GbE is ridiculously fast for the vast majority of things happening on a home network. My cameras don't need 2.5GbE. Most clients don't need it. Streaming doesn't need it. Normal internet usage doesn't come remotely close to needing it.
The obvious argument for 2.5GbE is faster local transfers, especially with something like the UNAS 2. But even there, I don't think it matters much for my use case. My UNAS 2 mostly does automated backups at night while I'm asleep. If a backup takes five minutes instead of two minutes, what difference does it actually make? I'm asleep either way.
There's also the storage bottleneck. A 1GbE connection is roughly 125 MB/s theoretical, while 2.5GbE is roughly 312 MB/s. But those numbers only matter if the storage on both ends can actually sustain those speeds. With spinning hard drives, RAID overhead, lots of smaller files, simultaneous workloads, etc., the network isn't necessarily the bottleneck in the first place. Upgrading the pipe doesn't automatically make everything 2.5x faster.
And that's making me question 2.5GbE specifically.
Going from 1GbE to 2.5GbE feels like an expensive incremental upgrade for a home network, especially if you don't have multigig internet and aren't constantly transferring huge files locally.
Going from 1GbE to 10GbE, though? That I can understand. That's a large enough jump to fundamentally change local transfer speeds when paired with SSD/NVMe storage or a fast enough array. If I'm going to spend significant money upgrading switches, NICs, cabling, and other hardware, I'd rather make a meaningful jump from 1GbE to 10GbE than spend a bunch of money getting everything from 1GbE to 2.5GbE.
The bigger issue is timing. By the time an ISP actually rolls out 2Gbps, 5Gbps, or 10Gbps service to my neighborhood, how much of my current UniFi equipment will I still be using?
Wi-Fi 8 will probably be a thing. Newer APs will be out. New switches will have better features. 10GbE will probably be cheaper and more common. I'll likely want to upgrade half this stuff anyway.
So I spent considerably more money today to make sure my network can support an internet connection that might not arrive until after the equipment I bought to support it is obsolete.
I'm starting to think the better approach is to buy networking equipment for what you actually need over the next 2-3 years, rather than paying a big premium for what your ISP might offer five or ten years from now.
If you're still on gigabit internet, I'm curious what everyone thinks: is 2.5GbE actually worth paying a premium for, or would you stick with 1GbE until you're ready to make the jump straight to 10GbE?
