Two my understanding a hub just splits the speed. So a gigabit Hub with let's say 5 ports would give each of the 5 ports 100mb speed regardless if a device is using their 100mb or not

If there was such a hub, you may average 100Mbit per port but it's not guaranteed because of packet collisions/resends on a hub. For that matter, you wouldn't be guaranteed 100Mbit per port on a switch either but in reality, it shouldn't be a problem with the switch buffers.

I could do that, but I think you misunderstood the problem. The reason I'm running a cat 6 cable was so I only have to run 1 cable and utilize the speed of it and connect up to 10 devices and maintain 1 gigabit for each device. I don't really need any device to run at 10 gigabit speed

I think you are fundamentally misunderstanding how switches work compared to older hub tech. Ten devices connected concurrently to a single 1Gbps switch will still each operate at 1Gbps because the packets take turns. You don't need a 10 Gbps switch to have 10 1Gbps connections.

I think running CAT6 is a great idea....for the rest of it I think you are spending way to much effort and brain power worrying over nothing. You simply do not need 10Gbps in any household setup unless: A) You have some ridiculously fast internet that runs in the highest percentile of the country or B) you are installing a home server with a RAID setup with a 10Gbps NIC that can deliver those types of transfers simultaneously to all of your devices.

Remember, you can only go as fast as your slowest connection. If your internet connects at 1Gbps, then there is zero reason to do 10Gbps unless you have a server as described above.

I already said this. I don't want any device to run at 10gb. I only want to use a 10gb cable and split its bandwidth among let's say 10 1gb Ethernet cables

I understand, but what you want to do makes no sense based on how Ethernet works today.

Can I ask you what type of data load you are expecting that will saturate a 10Gbps pipe, which is exactly what you are describing when you say you want 10 1Gbps connections to "split" bandwidth. Under normal operating conditions in a home environment, only a handful of devices are likely going to be transferring what could be described as substantial data, and even then you will be limited by your internet connection, not your ethernet infrastructure.

I think your lack of knowledge of how ethernet works is causing you to dramatically over-estimate your real world requirements.

I have a PC that needs a dedicated 1gb connection. And the rest of my devices are fine with a gigabit switch. So that's why.

Ok. I'll make one final comment. If everything terminates at a 1Gbps router from which your internet is distributed, then your intention is fruitless because all systems will still be sharing a single, solitary 1Gbps pipe to the outside.

If your internet connection actually supports 10Gbps from the modem, then I take back my comments; however, if it is 1Gbps like most are, then I think you are wasting money.

I wish you luck.

Yes and my internet service is only 130Mbps. I need that 1gb connection for my PC only because of local file transfer a which I will use a lot.

Why would you be file transferring a lot? If you are just streaming local movies, you won't saturate those connections at all. If you are trying to run programs and do full on editing over network, well I think your going to run into problems there. In fact only a PC is going to max out 1gbit.

I've yet to see ONE person that actually can fully utilize a 1gbps connection. Even a friend of mine who does video editing can't because he doesn't rely on a network connection for his video storage, he uses thunderbolt. Everyone that I've heard say they NEED 1gbps really doesn't ever utilize that. Even if your internet is 100mbps, very few servers can actually deliver you content at that speed. The only way 100mbps internet is useful is when you have several people in your house, all doing internet streaming at once.

As for the wiring, if it's a new house, put two cat6 in each room all leading to one central spot and put like an 8 port gigabit switch in there to connect your devices up.

Ok I'm just gonna explain my whole network setup: modem in basement connected to router in basement. Gigabit network switch connected to router. Servers,nas, and patch panel connected to this switch. Now, from what the conclusion seems to be is this: to my living room, I run one cat 5e or cat 6 cable and buy a small 4 port gigabit network switch to connect the devices their to the network. Then, another room has a PC that I usual send pictures and file and such to the nas. I will need a seperate Ethernet cable for that since my network transfers are going to be over 100MBps. So that means I will need to run another cat 5e or cat6 cable from the PC all the way to the patch panel in the basement correct? And no, their is no way I'm going to have this PC on one cable. Usually our living room has an Apple TV that is almost always being used with AirPlay and streaming, I really feel their would be a speed limitation if I don't have a sepereate cable for the pc

Run a pair of cat6 between basement and upstairs. You can plug the patch cable coming from your PC into one of them.

What features does your basement switch have? LACP? Interface usage statistics?

If you really want this, you need something like this. Two of them in fact.

Streaming normally takes less than 5Mbps ( high quality). So you will not have any problem with your file transfers if someone stream at the same time. In some rare cases you loose like 13% if something else maxes your internet on that cable (130Mbps). But if it is just TV streaming you loose less than 1%.

Just use one cable with a switch in the end and you're fine. Put the energy into something else in your IT-setup instead.

LOL at that price that's not happening. I think I'll just run one cat 6 cable and use a gigabit switch in the living room. Then from their I can run another cable to the room with the PC and also just connect everything to the switch.

If it I no trouble for you to run two cables then do it. Realistically you don't need more than a gigabit switch.

Yup. If you are running one cable, the expense of running two to the same location, in materials, is about...err, possibly $15-20.

You now have double the possible traffic speed between the two locations.

Typically heavy streaming is only going to hit you for probably 10-15% of your bandwidth. So even if you only have a 1Gbps link, you are still talking getting 100-110MB/sec for the file transfers with 1080p video streaming supposing that the traffic is going in the SAME direction.

If the traffic is going in opposite directions, there is no impact (other than ACK packets), as the links are full duplex, 1Gbps each direction. Traffic on the other side of the highway doesn't impact you on your side of the highway.

If the streaming is occurring from the same device that you are doing file transfers from/to (IE streaming from the NAS while also transferring files from/to the NAS), you are going to probably be looking more at disk limitations, memory footprint issues or a combo of both, more than you will be network link issues. Well, at least since I see you mentioned you have a NAS, which are generally not performance beasts.

Wow thanks for that information. I didn't know Ethernet cables worked like that. Where there's 1gb link up and down

Yeah, 100Base-TX, 1000Base-T and 10GIGBASE-T are all full duplex. That means they can pass 100/1,000/10,000Mbps of traffic in each direction at the same time.
