With yunohost I have never burnt any sd, even if I got some blackouts.
The reason why (probably): paying for a good quality big one. One of those 256GB and premium tier (sorry I don’t remember the codes on them but you can easily check them)
Nonetheless, I have 3 backups of that data tho. If it’s just about “using” it I wouldn’t worry. If you wanna stack films series etc, backup on hard drives :)
