I’m looking to replace my sff J5040 Wyze machine. Its still plenty fast enough, but storage has become an issue with its limited USB endpoint availability of ~50 device limit.

I know that just switching it up to a newer Intel system could give me double the endpoints because of the two XHCI chip setup, but I was thinking that if I’m going to replace it, I’d like to not limit myself.

As such, even though Ryzen is far faster than I need, it does now support USB4. Does anyone know if the switch to USB4 would give the system a larger address range and have more than 127 USB devices or is that limitation still in place and I might as well not waste my money?

    I know it’s not your question, but you might get much better results from a SAS card and adding SATA SSD drives. You can slowly upgrade an ATX system to meet increased power and space needs. I have done the same using truenas and it’s working great.

    Continuing to add USB devices does increase the serial traffic per bus since it is shared. Increased traffic increases errors, lowering your bandwidth further.
