Rebranded Ethernet Technology Consortium Unveils 800 Gigabit Ethernet
With an increasing demand for networking speed and throughput performance within the datacenter and high performance computing clusters, the newly rebranded Ethernet Technology Consortium has announced a new 800 Gigabit Ethernet technology. Based upon many of the existing technologies that power contemporary 400 Gigabit Ethernet, the 800GBASE-R standard is looking to double performance once again, to feed ever-hungrier datacenters.
The recently-finalized standard comes from the Ethernet Technology Consortium, the non-IEEE, tech industry-backed consortium formerly known as the 25 Gigabit Ethernet Consortium. The group was originally created to develop 25, 50, and 100 Gigabit Ethernet technology, and while IEEE Ethernet standards have since surpassed what the consortium achieved, the consortium has stayed formed to push even faster networking speeds, and changing its name to keep with the times. Some of the biggest contributors and supporters of the ETC include Broadcom, Cisco, Google, and Microsoft, with more than 40 companies listed as integrators of its work.
[...] All told, the 800GbE standard is the latest step for an industry as a whole that is moving to Terabit (and beyond) Ethernet. And while those future standards will ultimately require faster [Serializer/Deserializer (SerDes)] to drive the required individual lane speeds, for now 800GBASE-R can deliver 800GbE on current generation hardware. All of which should be a boon for the standard's intended hyperscaler and HPC operator customers, who are eager to get more bandwidth between systems.

Its great that datacenters have such a fast bus speed, but when will we move beyond the 1 Gbps at home and offices? it is 20 years old and our devices and specially our storage drives have greatly exceeded what the current speeds can offer.
I have a home server with 60TB of drives (about 25TB of data stored in it), I dread the day I will upgrade the hardware and have to copy the data over to the new hardware, the pipes are becoming too small.
I know that there are 2.5G, 5G and even 10Gbps cards that a mortal like me can by, but anything over 2.5G is quite expensive and the switches are almost non-existent or professional class with a heavy price tag.

Yeah, $70-$100 per port is pricey. Eventually you will hit the point where it becomes worth it so save money every day by not waiting on the network/storage limitations you're hitting with 1 gigabit.
I was hoping that the "promise" from Aquantia of $30 per port for 10GBASE-T would come true at some point this year, but everything is being slowed down by this coronavirus thing. Home/small businesses are being hit especially hard and I doubt networking is on the top of their concerns for most of them.

By my math, transferring 25TB of data over 1Gbps networking would take less than 5 days. Unless you're planning to upgrade the hardware a couple of times a year, I would consider the upgrade cost of faster networking gear not a worthwhile investment.
Did I calculate incorrectly? On my home network, my router and switches advertised at 1Gbps actually top out at about 650 Mbps sustained throughput. I ran some sloppy benchmarks between machines with netcat. 650 Mbps transfers 1GB in 13 seconds. 25TB = 25,000 GB, 25,000 * 13 / (60 seconds in a minute) / (60 minutes in an hour) / 24 (hours in a day) = 3.76 days.
Another possibility that could be less expensive is bonded ethernet ports ( https://en.wikipedia.org/wiki/Link_aggregation [wikipedia.org] ). At my old employer we would do that. It might be cheaper to set up your machines that require the fastest throughput that way - as long as all of the switches and firewalls between support it, you could get 2Gbps or 3Gbps - maybe even with the hardware you already have.

I am afraid the home and SOHO will always lag MORE than the current tech permits. Not only because of economy of scale but because YOUR CONTROL OVER YOUR DATA is a bad thing for the system.

30-70 for the SFP+ modules for each port.
100-200 dollars per 10G ethernet card.
Expensive compared to what motherboards/cpus/memory costs right now, but not paritcularly expensive compared to expansion cards of the past, and quite effective if you want 10G networking.
For anyone who doesn't know CAT5/5E is good enough for like 20M 10G pulls, Cat6 for 30M pulls and Either 6E or 7 for 100M pulls. For practically anybody's use case the 5/6 cabling will be plenty high quality, and anyone running a 100M drop today should just invest the added money in fiber adapters and wiring and benefit from electric isolation between networks or nodes. Also lowers EMF broadcasting in case you're worried about someone snooping on your network traffic with passive wireless suveillance techniques.
