I'm in a rural city in Thailand, fiber 2Gbps is $50 / mo. And this is just for normie. Like unimpressive.

But is that within the city / country, or to outside the country, too? International bandwidth can be completely mediocre compared to local bandwidth. What I do is change the Server in speedtest.net to one in New York / wherever I have business in and test it out (from Hong Kong).

I work remotely with american friends for years, video meeting has always been smooth (I never test traceroute though)

How affordable is $50 in rural Thailand compared to the USA?

$50 is about 1 week of 3 meals consumption per day (lower middle class)

So a bit under $2.50/meal. That’s very comparable to lower/lower-middle in the USA.

In neigbouring Germany, we had a lady from Deutsch Telekom asking us today if they should build a 250 Mbps line to our building!

Telekom is cancer, especially their peering. 250mbits sounds fine though, I haven't upgraded from that yet, there are way too few instances where it restricts me to pay anything more.

Stupid question, but if your hard drive cannot write 25Gbit/s , how is it handled? I don't knwo anything about SSD so maybe 25Gbit/s is easily achievable, just talking from my experience of copying from a USB Drive to my local disk.

The fastest internal SSD in a Mac now can write at 3.3GB/sec, so it would be able to keep up with 25Gbps connections, barely.

Average SSD write speeds are usually around 1GB/sec these days, but most folks could build a RAID of several SSDs and be able to keep up with such a connection, as well.

I would also assume that most folks who would bother to install 25Gbps, or anything close, probably have a lot of devices in their homes to take advantage of it at once.

Personally, I find it very hard to saturate the 1Gbps link I have. Most servers won't push more than around 200Mbps out to you, and I'm basically never doing 5 tasks at once that are that bandwidth-intensive. But it's nice to have some overhead, just for fun.

I would imagine an NVMe SSD would be capable of handling most, if not all, of that throughput for sequential reads and writes.

No %#*^ing way is he saturating a 25gbit connection to download a PS5 game — not on Sony’s EMEA servers anyway. He’d download the largest PS5 game out there (Borderlands at 50GB) in a minute anyway — probably before he could reach the full 25gbit. On a gigabit connection, he could download Borderlands in under 7 minutes. If that’s too long too wait, then having a faster connection isn’t this guy’s problem.

The only use case I can think of would be bit torrent where lots of peers housed in server farms could lead to full saturation. I’ve seen download speeds at 150MB/s. That’s still a measly 1.2Gbit. But even when you’re talking about downloading remuxed 2160p files (~50-75GB) or the occasional collection (~100-200GB), I don’t see the need since it takes time to connect to the swarm and saturate those connections. Unless of course you want to seed it to the whole world.

Cool to have such big pipes, and I’m glad Switzerland is doing some good for science and proving to other ISPs that there’s profit to be had in avoiding rate limiting, but this is so wildly unnecessary.

Modern SSDs can handle it: 25Gbps is ~3GB/s, which you can do with a PCIe 3.0 NVMe SSD. PCI 4.0 NVMe SSDs can do 5.1GB/s, or ~41Gbps.

At 25 Gbit/s your computer may likely not be able to keep up, unless you have NVME based SSD. We are talking about 3GB/s+ which my 24-drive NAS (old) can’t get beyond 2.6 GB/s with ZFS. Absolute madness. But this kind of bandwidth isn’t meant for a single machine.

In the end it's just an arms race with basically no use cases. You could call it future proofing but the switches will have to be replaced before such speeds could realistically be used (8k/16k video or sth like that?)

Having fiber without pon is great, means no new infrastructure for decades. But anything above 10gbits will be too much to use realistically, even for smaller companies.
