Storage requirements

<pre>Computer storage requirements for various digitized document types:

1 scanned page (8 1/2 by 11 inches, A4) = 50 KiloBytes (KByte)
(on average, black & white)

1 file cabinet (4 drawer) (10,000 pages on average) = 500 MegaBytes (MByte)
= 1 CD (ROM or WORM)

2 file cabinets = 10 cubic feet = 1,000 MBytes = 1 GigaByte (GByte)
10 file cabinets = 1 DVD (WORM)

2,000 file cabinets = 1,000 GigaBytes = 1 TeraByte (TByte) = 200 DVDs

1 box (in inches: 15 1/2 long x 12 wide x 10 deep) (2,500 pages) =
1 file drawer = 2 linear feet of files = 1 1/4 cubic feet = 125 MBytes

8 boxes = 16 linear feet = 2 file cabinets = 1 GByte (Gigabyte)
8,000 boxes = 16,000 linear feet = 1,000 GBytes = 1 TByte (Terabyte)
