Review on 📸 512GB High Speed Security Digital Memory Card Class 10 for Camera, Videographers & Vloggers: Compatible with SD Card Devices by Hunter Schneider

I have stored a few video files on this card and although they all worked fine immediately after copying the files there, after a few days about half of the files stopped playing shown as damaged. By the end of the week, all files were corrupted. I replaced all the files, checked that they were working, and over the next few days, all the files started deteriorating again. maybe it's ok with simpler text files, but it's useless to me.
