File Sizes and Types

How Many Pages in a Gigabyte?
 
There are a number of factors that determines how many pages are in a gigabyte. Different document types will generate very different files sizes and take up more space. For example, a Microsoft Word file with just text and no graphics would take up a relatively small amount of file space, but a paper document that has been scanned to a digital, PDF file format image with hidden searchable text can result into a large amount of disk space. The table below summarizes common file sizes based on various document types to help determine how much storage space will be needed when subscribing to NetDocuments. (16-17,000 Word Documents = 1GB of storage on average)

PDF files are approximately one-tenth the size of a TIFF image, making PDFs much faster to transmit and download. Benefits of PDF over TIFF: 1) Searchability, 2) file size 3) clarity, 4) universal compatibility.

More Information:
A terabyte is a trillion bytes, or a million megabytes, or 1,000 gigabytes, as measured by the hard-drive industry. (There are actually two conventions for calculating megabytes, but this is how the drive industry counts it.) As a reference, the print collection in the Library of Congress comes to about 10 terabytes of information, according to the How Much Information study from U.C. Berkeley. The report also found that 400,000 terabytes of e-mail get produced per year. About 50,000 trees would be necessary to create enough paper to hold a terabyte of information, according to the report.

A 1-Terabyte drive can hold:

About 330,000 3MB photos
or 250,000 MP3s
or 358 Movies
or 1000 hours of video

An hour of standard video takes up about 1GB, while an hour of high-definition video takes up 4GB.
