I have made an image. One sd card already died, but it worked for a long time. It was at least readonly, and I get most of the files off (I had backup, but I wanted to get the most latest files). Movies and series are on 5TB hard drive, so I don't have to worry about that. But are usb sticks really more reliable? My friend is using home assistant and he moved data partition to usb stick, just becaues he heard usb sticks are more reliable than sd cards, but not long after that, usb stick stopped working.
