storing 6 rubbermaid tubs of photo albums?

I copied a lot of old photos and the results were excellent. I used a copy stand and could zoom in on various photo sizes. I figure if the pixel count was adequate to take a picture covering virtually miles of width, that taking pictures of 5x7 or whatever inches would be adequate. many of them were taken with an old 750,000 pixel ??? sony that took them on a 3 1/2 inch floppy.
better cameras gave images that weren't appreciably better.
and you didn't have to wait for the image to be scanned, instantly copied.
