eMMC has been far more reliable for SBC use in my experience so far, compared to SD and microSD cards.
For example, Raspberry Pi Compute Module 4 has variants with different sizes of eMMC.
Also, making the rootfs read-only goes a long way. In Raspberry Pi OS you can go into the raspi-config menu and choose Performance -> Overlay, something like that to make the rootfs readonly with an overlay fs that exists in ram only. Depending on your situation it may be useful to enable this. (Anything you actually want to persist you’ll have to write to another attached storage, or send over the network to somewhere else.)
- tombert 3y agoThe last one I used was the Nvidia Jetson Nano. I'm sure there's a way of getting eMMC working on there, but after frying the fifth of sixth microSD card I threw my hands in the air and decided to go back to Intel. I wonder if the NixOS tmpfs trick could be useful for something like this though...
