The 8 port at $60 is a good deal also, and is what I'd recommend people pick up over the 5 port.

If you have a NAS that you are frequently accessing and a fairly recent router/mesh/home network setup already with 2.5G ports then you will likely benefit from 2.5G even as a home user . Not a must by any means but a welcome upgrade for very little work and money

A 1 gigabit port consumes/dissipates about 0.25W of power/heat. This means 16 ports of gigabit use about 8-14W. A 1600G port uses something like 25-30 watts per port for transmission and then 20-40 watts per port for processing, or 45-70 watts per port, meaning a 5 port switch would run 300W which is going to be spicy both in heat and noise. 10G RJ45 uses between 2.5-5 watts of power per port, which is is at least 10x what 1G uses and is still challenging to manage.

However, 10G SFP+ connections - fiber-optic 10G? It uses 0.1 to 1.5W per port when using fiber or DAC (the SFP+->RJ45 converters use up to 3W, which gets really hot and can burn ports out if there isn't enough active cooling, if you use them, ideally use the long range ones on short runs). It doesn't have to do as much processing as 10G RJ45 does, so it's much more efficient and the gear is often much cheaper. But home users don't do well with fiber and DAC cables top out at limited run lengths, so it's not widely adopted by home users.

This TP-Link 5 port 2.5G unmanaged switch is framed as a simple way to add faster wired networking without upgrading the whole home network. It fits well for NAS backups, Steam file transfers, and other local traffic when both devices support 2.5G, while the rest of the network can stay at 1G. The price is viewed as reasonable, and 2.5G is described as a practical middle ground versus pricier 5G or 10G gear. The main caveat is that the 15 percent Prime Visa back offer may not appear at checkout, and an 8 port version at $60 is preferred for most setups.

it's nearly double the price so outside of 3 additional ports which you may or may not need , is there any other reason why someone would want it over this one ?

I watched a video about the NICs being used in data centers recently, and it made me realize how far behind the consumer space is. Datacenters are using 1,600 Gigabit ports now. 640 times faster than this.

I'm sure those are crazy expensive, but you would think that at least 10G would be commonly accessible to consumers by now.

Regarding the product: You don't have to upgrade your whole network. You can just plug your 2.5G devices into this switch, and they will talk to each other at 2.5G, and the rest of your network at 1G (or whatever the rest of your network is). So you can use this without upgrading your router or other switches.

Most home user don't need more than 1 Gbps of speed. Those who need 2.5G or 10G are likely to be professionals who need to transfer large files over the network constantly.

Prime special offer is valid until Sep 30. So, 2 months to decide, no hurry

YMMV there, apparently - the 15% offer is not present when I check out with this. It just shows the normal 5%.

But I have 5Gbps Internet. Over 1Gbps Internet is more and more common these days. If you want to share that with multiple devices (that have over 1GB LAN ports), you need a capable switch. Or am I misunderstanding how it works?

This is a good point, but for wasted energy reasons, its totally unnecessary for home users to have 10gig plus home networks. Most, if not all, home internet plans from Xfinity / T-Mobile / Rogers are in the 500mbs - 2 gig upload / download range. AND most home users are using their home network bandwidth almost entirely for internet access (Netflix, DIsney+, etc.) so it entirely makes sense to have a sweet spot 2.5G home normie network speed aligned with that.

You will need switches that offer equal or over 5Gbps to take advantage of the full 5Gbps internet bandwidth in your case.

You'll need more ports later. Trust me! 😀

Or, if your internet is more than 1 Gb/s..
