Most computers today hold 80 to 120 gigabytes of hard drive space. (Servers can hold more) To search a computer manually for a document, or a word or a phrase INSIDE of a document, could take several days. 1 single gigabyte of storage can hold as much information as one copy of the Encyclopaedia Britannica (2,619 pages). As an example, the Dell Dimension 8250 comes with a 120 gb. hard drive as standard equipment. The 120 gb. hard drive will hold 314,280 pages of text. this is the answer i just found at this website: www.dalmaninvestigations.com/id3.html i hope this helps you.
