Sanity check: Install on USB flash drive?

I’m already running HA 78.3 on Raspian w/desktop. I’d like to migrate to, as I never use the desktop on Pi.

So, can’t I just use etcher to write the image to a 32gb USB flash drive (Sandisk USB 3.0 32gb Flash drive)? Wouldn’t that be as stable as the little SD memory card it currently works on?.
The Pi3B+ can easily boot from USB. So, is there a reason it wouldn’t be good to do?

There are several topics on this forum with info about this. Short story, yes and it’s faster and more stable.

You can also move an existing install if you use dd on a Linux machine to copy the SD card to the SSD. You then just need to change the boot config to change the root partition from mmcblk… to sda…
