I just upgraded to 10G for my home network (well my servers anyway).

There are a few things to take into consideration if you're thinking of it.

1) Disk speed - 10G maximum speed is around 1250MB/s - SATA spindle disks max out at around 150MB/s, SATA SSD top out around 600MB/s and NVME drives can saturate a 10G link. So if you've only got older PC's without NVME capability the best you can hope for is around 600MB/s with SATA SSDs. 

2) You could use a PCI NVME adapter but you might run into problems with PCIEx slots on your motherboard. You must have your 10G card in a x8 slot for full speed, with a video card in your x16 slot you might run out of fast slots for your NVME adapter.

i't's not that expensive for 10G networking gear, I picked up (in $AUD) an 8 port Unifi 10G switch for $400, Intel x520 dual port 10G nic's for $100 ea, I was lucky and found a bulk lot of 20 Intel SFP+ modules brand new for $5 each. I had to fork out for new SFP+ modules for my Unifi switch I think around $60 each (you really need compatible SFP+ modules for your card/switch or you could run into issues). Some 1M/2M/3M multimode OM4 cables for $20-$40 each.

I put two samsung SSD's in each of my machines that don't have NVME drives in a striped raid array and my network runs mostly at 600MB/s.

I do have a use for the speed as I back up my main server to a backup server every night so the extra speed is a blessing. I do transfer large files to and from my main pc and server and what took hours takes no time at all.

But if all you do is browse youtube and send a few emails the cost of 10G really isn't worth it, but if you regularly transfer large files around your network or make large backups it's really handy!

.... The only place I want data loss is on my credit card!
