Gigabytes, Terabytes, And Petabytes Hard Drives

Bigger Is Better For The World Of Hard Disk Drives

I remember when I thought a 20 megabyte drive was a large size drive. Then when the gigabyte drives came out, and we all said, "Wow!" Now the terabyte drives are here, for personal computers. Here comes the terabyte hard drive | Tech News on ZDNet

Amazing, and the storage keeps growing! What's next, the Googolbyte?

University of Berkeley, How Much Information? 2003 Executive Summary
  1. Print, film, magnetic, and optical storage media produced about 5 exabytes of new information in 2002. Ninety-two percent of the new information was stored on magnetic media, mostly in hard disks.
    • How big is five exabytes? If digitized with full formatting, the seventeen million books in the Library of Congress contain about 136 terabytes of information; five exabytes of information is equivalent in size to the information contained in 37,000 new libraries the size of the Library of Congress book collections.
    • Hard disks store most new information. Ninety-two percent of new information is stored on magnetic media, primarily hard disks. Film represents 7% of the total, paper 0.01%, and optical media 0.002%.
    • The United States produces about 40% of the world's new stored information, including 33% of the world's new printed information, 30% of the world's new film titles, 40% of the world's information stored on optical media, and about 50% of the information stored on magnetic media.
    • How much new information per person? According to the Population Reference Bureau, the world population is 6.3 billion, thus almost 800 MB of recorded information is produced per person each year. It would take about 30 feet of books to store the equivalent of 800 MB of information on paper.

The One Gigabyte Camera

By now you may have recognized this blog is about Big Things.

Enter the idea of an affordable One Gigabyte Pixel Camera with 100x optical zoom.

Why on earth would you want a camera that would give you that high a photo resolution? What could an average individual do with that kind of power in their hands?

I currently have an Canon eight megapixel camera with a one gigabyte removable hard drive that can hold hundreds of pictures. This 8 megapixel Canon is actually a second generation camera for me in as much the first one was a 1.3 megapixel camera that provided some basic digital pictures. The new 8 and 10 megapixel digital cameras have certainly pushed out the 35 millimeter photography industry. One needs to only look at the revenues of Kodak to see that film, and film processing, is becoming less and less of a money earning proposition. Kodak has in recent years ventured into digital cameras on a large scale.

The reasons for extended digital photography are many fold. For example: Taking detailed pictures of areas involved with mapping of the landscape could provide excellent detailed renderings of geographic changes taking place. Or, for the average person to be able to take close-up views from great distances away would open a whole new world to the amateur photographer. Imagine being able to take a single picture of a landscape scene, with a farm house, tractors, and animals all in different area locations of the picture. Then with a computer, the image could be cropped for each individual segment from the same picture and see the kinds of details that could only be viewed with telephoto lenses and many pictures later with the old way.

For examples of what can be accomplished with a one gigalpxl camera, visit the Gigapxl Project Gallery for detail photos. Click on the pictures and scan down the various cropped detail views. Imagine the possibilities.

Honestly, I do not know when an affordable camera of this magnitude will become available to the general population. But, I will say, "never say never." Remember, technology changes, especially in the world of nanotechnology are occurring at break neck speeds. It just might be around the corner that a new way of doing something will leapfrog the old and create something entirely different that no one would have dreamed about yesterday.

Random Internet Thoughts

by: James A. Warholic

As individuals in this world sometimes we take ourselves much to seriously.

An individual can make a change in this world for the better.

Don't get rapped up in all the details.

Ideas seldom flow in logical form.

Creativity can not be stopped.

Challenges bring upon new unexpected results.

Ideas are the building blocks.

Starting a project can be harder than doing it.

Projects are never finished.

The mind is an amazing place indeed.

Talking about something is easy.

Writing about something is a little harder.

Thinking about what you are writing is tougher.

Reading what you wrote sometimes makes no sense at all.

Revision is always going on.

After reading what I wrote I realize that the random thoughts are not so random.
