I have a large collection of video files most of them in mp4 format. I currently store them in SD Cards. Once I finish filling a SD Card I lock it and never use it again unless I need to read the files.
My intention is to be able to read those files in 30 years. I have been researching and it appears that even If I don’t use the card and properly store it some data degradation will occur. Is that right?
I also tried to compare it with other storage Medias but most of the information I have found online don’t come from “official” sources.
There is any way of refreshing the charge in SD cards without copying in and out the information manually or should I replace the cards every five years?
