Generally, the multiple controllers on single PCIE cards are pretty expensive because very few even bother to make them, even for just two 10gb controller models. So $450 for an 8 port all 20gb USB-c with full bandwidth across all ports over multiple controllers is a decent price.

It baffles me that it seems so difficult to find anything that actually utilizes the PCIe bandwidth and possible lanes and full USB bandwidth per connector.

The 66088-LED is a high intensity visible light source. Its 15 W white light LED allows it to emit exclusively visible light, omitting ultraviolet and infrared wavelengths, in a much more compact package than typical arc or Quartz Tungsten Halogen (QTH) lamps. Additional benefits to traditional arc or QTH light sources include a much more efficient energy operation and a much longer lifetime with a typical 30,000 hour operation time. This light source can be used as a simple plug and play, standalone device by using the buttons on the front panel, or integrated into a fully automated system. Light intensity can be controlled remotely via an RS232 port, an external 0-5 VDC power supply, or with pulse width modulation from an external digital signal. The 66088-LED is ideal for fiber coupled applications. A liquid light guide should be used due to its high transmittance in the visible wavelength range. For coupling a light guide with Oriel’s 11 mm ferrule termination, contact your Newport Technical Sales Engineer for advice on optimum coupling. The adapter on the front of the light source is also adjustable, capable of fitting most existing light guides in a setup.

https://www.aliexpress.com/item/1005005414052743.html Something like a boatload of these? I’d say it’s possible, even probable, that there’s really just not enough demand for a card to do 8x20Gbps over USB. I have a lot of trouble even imagining what that could be for. External NVME drives? Why do you need all 8 of them to be full speed at the same time? It feels to me like it’s something where, if you need this kind of connectivity and bandwidth, USB isn’t the way to do it. Would even go so far as to say modern high-speed USB standards have very little place in the mainstream market as is, and mostly only make sense for external GPU docks that actually just use it as a PCIE passthrough device anyway, and would make more sense to have an actual PCIE passthrough standard for it, rather than piggybacking off the flaky type-C connectors.

There is a lot you could use it for. There is also not much middle ground. E.g. a multi-card where 2 ports have 20gbps and the rest have 10 gbps each would be good too.
