should just use m.2 2230 nvme. should be user replacable, its okay if it needs to be disassembled and its a 30 minute job, but that would solve a whole lot.

SD Express is PCIe and much smaller, but a full sized SD card still isn’t small. Supposedly microSD Express exists but I’m not sure that I’ve ever seen it…

Aren't the speed constraints on SD cards due to the controllerless single flash chip design rather than the connector format? Unless you also shoved an ssd controller on the SD Express card I can't see it being much of an improvement.
