Used t490 / t480. Can you elaborate on the “heavy limited by space”?

No I’m not catastrophising.

2024 is going to be the beginning of the end of us all

Yeah, I don’t know about that.

Of course those exist, but that does not make them standard compliant. Same goes for power supplies that don’t do handshakes. That’s not an issue if you exactly know what you need them for, but they’re not meant for the general public because you can use them wrong.

Theoretically you could build a male to male contraption from multiple adapters and a cable. Also you could be providing too much current to a device, however this is specific to the combination of adapter, cable and power supply you use.

I can’t quite figure out what would be the use cases where bcache would excel, except for hdds without cache or systems with very limited ram. Can you help me out with that?
