My now long-in-the-tooth camera makes JPG files of about 3.5 MB each. If I had 1TB of storage on board, it would be enough for about 285,000 photos.
The expected lifetime of the shutter mechanism in my camera is only about 100,000 shots. Even if I got lucky and my camera’s shutter lasted twice as long, this card would be large enough to store every photo the camera snaps in its lifetime, without ever deleting anything.
When the camera finally broke, I could fumble the card out and instantly drop it in a sewer drain, probably.
