        2.5GBASE-T and 5GBASE-T
        IEEE 802.3bz, NBASE-T and MGBASE-T are standards released in 2016 for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s. These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds. The resulting standards are named 2.5GBASE-T and 5GBASE-T. NBASE-T refers to Ethernet equipment that supports speeds of at least 2.5 Gbit/s and sometimes 5 or 10 Gbit/s, and that can automatically use training to operate at the best speed supported by the cable quality. Usually it also supports additional link speeds (10, 100 or 1000 Mbit/s) in connection with autonegotiation, depending on the capabilities of the equipment at the other end of the cable. Technology These standards are specified in Clauses 125 and 126 of the IEEE 802.3 standard. The physical (PHY) layer transmission technology of IEEE 802.3bz is based on 10GBASE-T, but operates at a lower signaling rate. By reducing the original signal rate to 1⁄4 or 1⁄2, the link speed drops to 2.5...

      @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 I was reassembling my niece's PC after they moved house recently, and couldn't get her graphics tablet to work. It just didn't respond.

      It wasn't until I moved one of the USB plugs to another USB port that it suddenly came back to life again.

      So much for universal, I guess.

      @flacs This made me wonder – how many actually different kinds of USB ports are there?

      These are what I came up with:

      1. USB-A 1.1
      2. USB-A 2.0
      3. USB-A 3.0/3.1gen1/3.2gen1x1 (5Gbps)
      4. USB-A 3.1gen2/3.2gen2x1 (10Gbps)
      5. USB-C 2.0
      6. USB-C 3.0/3.1gen1/3.2gen1x1 (5Gbps)
      7. USB-C 3.1gen2/3.2gen2x1 (10Gbps)
      8. USB-C 3.2gen1x2 (10Gbps)
      9. USB-C 3.2gen2x2 (20Gbps)
      10. USB-C 4.0 (40Gbps)
      11. 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.

      True, 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.

      @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"

      I'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 🤷

      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.

      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.

      @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.
