Well, I guess the question is whether the extra 32 GB of cells (approximately) in the 64 GB card get managed into useable space as sectors in earlier use go bad?
Or, maybe “other stuff” goes bad sooner? A while back I tossed an old card that developed issues with the contacts.
BTW, In this case the 32 GB card has a 2 yr. warranty and the 64 GB card has a 5 year warranty (and the 128 GB and 256 GB) have 10 year warranties.)
Um...that is not how memory works in computers.
Just fyi.
