Ok, let's see if I can figure this out.
One Page = 6460 characters
1 Gigabyte (GB) = 1,073,741,824 Byte
Therefore One Gigabyte = 1,073,741,824/6460 = 166213.90464396284829721362229102 pages.
So therefore, hard drives of the following volumes would require this many pages:
10GB = 1662140 pages
30GB = 4986418 Pages
80GB = 13297113 Pages
120GB = 19945669 Pages
160GB = 26594225 Pages
250GB = 41553477 Pages
1TB = 170203038 Pages
Now, One page = 0.16 ounces [

Therefore:
10GB weighs 265942.4 ounces, or 16621.4 pounds (Ok, now that's just freaky) (7 539kg)
30GB = 49 864.18 pounds (22 618kg)
80GB = 132971.13 pounds (60 314kg)
120GB = 199456.69 pounds (90 472kg)
160GB = 265942.25 pounds (120 629kg)
250GB = 415534.77 Pounds (188 483kg)
1TB = 1702030.38 pounds (772 027kg)
Oh, and the cost of sending 1TB from New York to San Francisco: $111849 (consisting of 24314 letters each weighing 70 pounds) or $4236888.75 if you want it Express Mail overnight.
