A quick google shows eMMC flash memory for the compute module...do you need to mindfully control writing to flash to keep something like this from nuking the boot device? Could be my choice of storage (whatever $4 buys at Microcenter) but the failure mode on my RPi weather station was SD card death. I'd hate to rely on that for a NAS.

Since some firmware update released in September 2020 it's possible to boot Raspberry Pi 4s from USB. It's a bit cumbersome to piece the info together, but it's there: https://www.raspberrypi.org/documentation/hardware/raspberry...

You can also boot the pi 4 via kind-of-special-sauce PXE. I wish they had just adopted standard PXE (why do we need a magic string? What the hell is going on with the three spaces in that magic string... Why can't we use the standard PXE way to specify the file to load?), but it's better than nothing.
