I got this from another list, was disseminated to some
people recently. It gives you an idea of the scale of
what they are planning for the 'new FamilySearch' that
we are all expecting as early as later this year.
The costs on storage, equipment, etc., are going down
all the time, but it still is beyond the comprehension
of many just thinking about how big the new site
eventually will be once they've scanned in just what
they have now, and others start adding in all their
How can you understand what a petabyte is when its
hard to understand what a billion of anything is?
Maybe this will help.
Gigabyte is the equivalent of a billion. We currently
use hard disk space on our computers measured in
kilobytes, megabytes, and gigabytes. A megabyte is a
thousand times bigger than a kilobyte, and so on.
gigabyte, are terabytes, petabytes, exabytes,
zettabytes, and yottabytes. They can be abbreviated
KB, MB, GB, TB, PB, EB, ZB, and YB.
18 petabytes is the projected storage capacity that
will be required over time for the new family history
system the Church is developing. To illustrate this
you can put over 4000 names from a genealogy
program on a floppy disk.
Floppy disk: 1.4 MegaBytes
CD: 700 MB or about 570 floppy disks
DVD: 4 GigaBytes or less than 6 CDs
HardDrive: 100 GigaBytes or 25 DVDs
HardDrive: 1 in your PC from 40 to 500 GB in size
10 inches of stacked 100 GB harddrives: 1 TeraByte
A Holographic Versatile Disc (HVD) holds 3.9
Library of Congress has 20 terabytes of text.
UPS has approximately 474 terabytes of information.
10,000 inches stacked 100 GB harddrives: 1 PetaByte
833 feet of stacked 100 GB harddrives: 1 PetaByte
833 feet equals about 3 football fields
1666 feet or worlds tallest building 101 stories,
holds 2 PetaBytes of 100 GB stacked harddrives
18 PetaBytes equals 14,994 feet of stacked
14,994 feet is almost 3 miles (15,840 feet)
Now common commercial hard drives are exceeding 500
gigabytes in size, so storage capacity totaling a
terabyte or more can be reached using 2 or 3 hard
disks, at a street cost of as little as USD $450
(www.newegg.com). At this rate, 18 petabytes would
cost as little as $8,100,000.00 . Since large scale
databases protect data with multiple copies in a
mirrored system, actual costs more than double.
Infrastructure that supports the system could cost
over 10 times that amount as a guess.
