Fair enough!
So you would suggest to get bigger and bigger storages?
Personally I would suggest never recording video. We did fine without it for aeons and photos are plenty good enough. If you can still to this rule you will never have a single problem of bandwidth or storage ever again. Of course I understand that this is an outrageous and unthinkable idea for many people these days, but that is my suggestion.
Another option: encrypt a sparse file rather than a disk volume. Mount the file to local filesystem and open and close it there.
