@lukasa already answered all the questions here but for others reading this, I thought it may be worth linking some other, very similar information available from [this thread](https://forums.swift.org/t/how-to-use-nonblockingfileio-for-repeated-writes/36206/2) (and [some images](https://forums.swift.org/t/how-to-use-nonblockingfileio-for-repeated-writes/36206/8) which may help) and [that example](https://github.com/apple/swift-nio-examples/tree/main/backpressure-file-io-channel) as well. I thought maybe reading similar thoughts explained in slightly. They discuss exerting backpressure from the network (HTTP upload) to disk (saving the uploaded file).
