Are there any that actually have a SFP+ port? That's all I want. No one wants to use 10g ethernet when DACs are cheaper than cat7, and you can just change it up to a $7 multimode when you need longer runs.
All these USB version names. I used to know what they all meant, but then the USB IF went ahead and renamed them all and made a bunch of versions have the same name and renamed some versions to have the same name as the old name of other versions. I have absolutely no idea what anyone means when they say USB 3.2 gen 2x2. I used to know what USB 3.2 meant but it's certainly not that.
Oh, it's fine. The lack of clarity is in keeping with the USB C connector itself, which may supply or accept power at various rates or not at all, may be fast or slow, may provide or accept video or not, and may even provide an interpretation of PCI Express but probably doesn't. It probably looks the same no matter what, and the cable selected to use probably also won't be very forthcoming with its capabilities eithe…
It gets even worse.
I now have two cheap Chinese gadgets (a checki printer and a tire inflater) that have USB-C ports for charging, but will only charge with the wire that came with the gadget. The other end of which is an old-style USB plug.
It seems that USB-C sockets are cheap enough parts to use them for everything, even if the manufacturer isn't going to put any actual USB circuitry behind them.
Edit: Three. I forgot about my wife's illuminated makeup mirror.

That link notes: "Card supports 10Gbit/s and 10/100/1000/2500/5000/10000Mbit/s Ethernet" Nice to see; some NICs are shedding 10/100 support. Apparently, it's not necessary to do this, even in a low cost device.
Low cost? The link mentions no price, only a "notify me" button as far as I can see. Does it show a(n estimated) price point for you somewhere?
10 GbE sits in a really weird spot for me, maybe I'm just not understanding something though. It's at most 1.25 GB/sec of bandwidth, yet it's relatively quite expensive. It's not sufficient bandwidth for getting good performance out of most SSDs, yet it's really excessive for any hard drives (except for RAID10 setups I guess). For SSDs you want thunderbolt (or 40+ GbE) connection for best latency and performance, and…
10 Gb is cheap! Mikrotik has a 4x10Gb + 1x1Gb port switch for $150 USD and an 8x10Gb version for about $275. I have the 8 port version. SFP+'s and fiber are cheap, like maybe 50 bucks for the SFP+ set and fiber. 10Gb PCIe cards are maybe ~$50 new on Amazon with Intel chips and cheaper on eBay - I bought used 10 Gb Mellanox cards for $25 each - "they just work" under FreeBSD and Linux. Copper 10 Gb used to consume waa…

To be fair they seem to have taken this often-stated criticism on board. USB 4's naming is more sensible, and they've pushed the simple data speed & power labelling that makes it easier to work out what you need.
Yeah, now it's USB4 Version 2.0 / USB 80Gbps / USB4 Gen4.
> USB 3.2 Gen 2x1 What the fuck
It just took them a really long and windy time to get there.

10 Gb is cheap! … $150 … $275. San Francisco checking in.
How much would they need to cost before you'd consider it cheap? If you want CHEAP then 10GbE is not for you in 2026.

Great site, thanks for the link. But holy heck, that "Also Known As" column is complete chaos. What the heck is wrong with the USB Consortium, do they have brain damage? Also, according to that table, "USB4 Gen 2×2" is a downgrade on "USB 3.2 Gen 2x2", since the cable length is 0.8m instead of 1m for the same speeds. Which is uhh unexpected.
The cable length is only for the spec. You can get longer cables that achieve the higher bandwidth, they're just not certified for that.
