My Garmin dash cam deletes the oldest files when the memory card approaches full capacity. I am not sure exactly what percent of full this corresponds to, but with the Edge it sounds like 200 files is the cutoff. I could see how that might be problematic if someone created huge ride files, say by sleeping without terminating a ride for weeks at a time. So if they indeed implemented it that way, they didn't anticipate the pathological exceptional case.

I don't know if it is user-configurable, but many OS for such devices let you choose to save a week of files, a month, or whatever, or delete them after upload (which has a slight risk). Garmin seems to hard-wire a lot of this stuff. More choices = more user error.
