Re that M.2 Ethernet card, that's a long untwisted ribbon cable. 100Mbit should be fine, but 1G or 2.5G? Sus.

- lmz 4y agoI take it you've seen PCIe riser cables like this one: https://www.amazon.com/Zer-one-7-5Inch-Extension-Flexible/dp/B07W4KV8ZK/ https://www.amazon.com/Zer-one-7-5Inch-Extension-Flexible/dp... If that sort of thing can work at PCIe rates I don't see any reason why that M.2 card can't. It's a lower bit rate plus theoretically a more resilient encoding for long distance as opposed to PCIe.
- theideaofcoffee 4y agoThe untwisted ribbon cable is fine for PCIe in short runs by virtue of PCIe data lines being a differential signal and if the length of cable is kept short(-ish). The max length of the cable should vary inversely with the generation, that is, max length of a flexible copper extender for gen v1 is longer than gen v3, more length introduces more noise which increases error rates. A well terminated cable should be able to use the full bandwidth of the bus. I'd be completely comfortable running x16 flat out at max rate with one of those. I don't have any hard-and-fast sources to back the above up, but punching 'pcie extender max length' into the Gargler should find you something to suffice.
