I’d avoid transcend. We had a LOT of customers report the beeping problem as soon as the Transcend card is full. Their older cards were ok not sure what they changed. We switched to Sandisk High Endurance U3 and Samsung EVO U3 a few years back and had very good results long term so far. Any brand card can fail early though.
A few reasons to format cards in camera more often is especially for Mac users. Mac OS leaves a bunch of hidden files on the card that can potentially trip things up. As good practice, It’s always recommended to format the card any time you’ve accessed the card via Mac or Windows. Some cards slow down over time and running the SD Formatter app (“overwrite” option) can get it going again. There are other reasons to format often Rick (Jokiin) has posted about many times but don’t have a historical link handy to it. I tell customers to put it in their calendar to format in-camera at least twice a year if you completely set it and forget it long term.
On an aside note: I use a Sandisk A2 Extreme (128GB and 256GB) in in two of my Dash Cams and never once had a failure. I use a Sandisk High Endurance 256GB and first one failed in a few months. I did an overwrite / low level format and it kept developing sectors. I even attempted to put other things on the card and they'd randomly wind up corrupted. Had Sandisk RMA the card and the new one works fine.
So any card can definitely fail. Even the most reliable. I also have a spare Samsung Evo Select 128GB in case I ever need a spare card.
