2 Tb?! All of my important docs fit on a 2 Gb flashcard.

Photographs? A friend of mine has never deleted a single image from his camera's SD cards. When it's full he's just buying a new one and storing the old one in the portable safe. So 50 of 32Gb cards is not that unrealistic in a long run for him.

Personally, I think that the photographic memorabilia's importance is overrated. I'm keeping about a gigabyte of really good family images, which I might want to print out some day, on another 8Gb flash card. The rest goes randomly to the free cloud storage (i.e. google drive, dropbox, spideroak), and to the social networks albums, blogs, wiki's, e.t.c.
