@kaia @flacs Presumably because it supports 5Gbps speeds (which really makes me wonder what chipset's used – I've only seen 10 and 2.5G higher-speed eth ports so far).

@flacs This made me wonder – how many actually different kinds of USB ports are there?These are what I came up with:USB-A 1.1USB-A 2.0USB-A 3.0/3.1gen1/3.2gen1x1 (5Gbps)USB-A 3.1gen2/3.2gen2x1 (10Gbps)USB-C 2.0USB-C 3.0/3.1gen1/3.2gen1x1 (5Gbps)USB-C 3.1gen2/3.2gen2x1 (10Gbps)USB-C 3.2gen1x2 (10Gbps)USB-C 3.2gen2x2 (20Gbps)USB-C 4.0 (40Gbps)USB-C 4 version 2 (80Gbps, not sure if commercially available yet)Do Thunderbolt3 and 4 count as USB? What about USB-C ports that support DP-Alt mode? And I didn't even touch all the possible power delivery options…Very universal indeed.

@jernej__s@infosec.exchange @flacs@mastodon.social I'm pretty sure USB-C can be USB 1.1 only as well, though I'm not sure of any computers with such a combination

@Sophistifunk retrospectively, i could happily live in the days of mouse connected via DB9 connectors, printers on parallel ports and monitors on VGA forever. 99% of things i'm interested in worked back then as well. only thing objectovely better is media compression. i don't long for video cds i have to swap out at half a movie xD

@vxo@digipres.clubI'm on the opposite side of this spectrum, I find it hard to justify even the gigabit ones for personal use 😅I'm mostly into text content on the Internet and I only get reminded of maximum network throughputs when I need to copy large amounts of video before going somewhere for more than a couple of days/nights — even in this case, storage is usually the main bottleneck 🤷@kaia@brotka.st @flacs@mastodon.social

@m0xEE @kaia @flacs Yeah, I realize I work with some edge cases. At work we have a big video SAN/library system and have to transfer great gobs of gigabytes back and forth for video editing and production, so I have actually been in the situation of staring at a transfer running over gigabit lan and thinking "this is taking a while"

@vxo@digipres.clubTrue, there are certainly use cases for that — especially in video production, in this case you can also afford SSD-based mirrored arrays to keep the storage end covered. But for personal use IDK — modern wireless standards, even those are more than enough for most of my needs.@kaia@brotka.st @flacs@mastodon.social

@m0xEE @flacs @kaia N-BASE-T, most likely RTL8157. Cheaper and much more energy efficient/cooler than 10GBase-T.

Thunderbolt 3/4 does not count as USB. (The very first Thunderbolt ran over mini-Displayport on Apple's, remember?). It got confusing with TB4/USB4 because people thought the standards were finally getting merged .. but they're not. But I think TB4 can handle PCI-Express signaling, so they're almost equivalent in connectivity at this point.

@djsumdog @flacs TB3 only uses USB-C port, but with TB4 things are more complicated – while USB4 doesn't need to support everything TB4 does, supposedly Microsoft said they wouldn't certify USB4 drivers that didn't support all transport modes, making USB4 and TB4 effectively equivalent.OTOH, in the previous post I was just counting all the different types of USB ports, and since TB3 and up use USB-C ports, they probably should count up there (as would USB-C ports that support DP-Alt mode).Also, Apple wasn't the only one with MiniDP TB2 ports – at least some HP laptops also had them.

huh .. interesting. But laptop AMD chips still can't do TB4, right? (I remember there were some hack to get TB PCI cards working on AMD on Linux). or can they now? I haven't kept up with this stuff in a while since the only place I use Thunderbolt is my work laptop/dock .. it gets confusing.There's also the DisplayLink protocol for some laptop docks, but I think that's just on top of the USB protocol. I know WavLink makes some PCI-E cards that can do DisplayLink too.
