I am not sure if I understand your question, but what I was hinting at is the reliabilty of the sd-card. I've had several Raspberry installations get corrupted due to power outage, which the sd-card can't handle at all. Back then I didn't get booting from SSD through a USB-Sata adapter working. I've read that it is easier now though. What is your experience?

Read-only sd card works pretty well though in my experience. You can make it rw for upgrades and remount to ro once done. All the files which need write access (but you don't care about preserving) can be "saved" to tmpfs.

  I'm currently using the read-only Alpine install for my Raspberry Pi based wireless AP. Quite functional so far.

  PITA With normal install you can just configure unattended-upgrades (on Debian at least) and mostly forget about security updates, they will just happen (can even set a schedule for reboots for kernel updates IIRC). But IIRC boot on card + root FS on SATA or USB-SATA works just fine and you only get some writes off occasional kernel update

I just moved my Home Assistant from SD to SSD and it couldn’t have been easier. Using the USB-Sata adapter I plugged my SSD into my Mac and then used Balena Etcher to dump the HA image directly to the SSD. Plugged it into my Pi and it fired up just like it would’ve if it had imaged to the SD card. I was pleasantly surprised with how easy it was and it’s nice to have HA running off of an SSD now.

  You can clone it while running as well [0]. For speed make sure the adapter is USB3.0 and plugs into one of the USB3.0 ports on the pi and also that it supports UASP and enable trim on the drive [1].
