How many atlases would fit into 20 terabytes?
If an atlas has 200 A4 pages,
each being 96,9375 square inches,
fulfilled with maps at 600 dpi,
32 bits per dot,
and one dot is 4 bytes;
then one page is 140 megabytes,
that multiplied with 200 equals 28 gigabytes.
Then 20 terabytes equals to 20000/28 = 714 unique true-color atlases.
