I found the description of it hilarious. Just imagine how a 1956 man's head would spin if he were transported to 2006 and saw how small and powerful hard drives have become.

Here's the 1956 man working with the pinnacle of his day's technology:

"So how many songs can this thing play?"

"Well... it only has space for one. And you can't really hear it over the noise of the hard drive."

He could put it on wheels and have his own primitive one-song iPod with him everywhere he goes (provided it fits where he goes).

Nifty. Near the end of the article, it speculates about Petabytes becoming available in the future.

What would a home user do with petabytes of storage? I can't conceive of a use for all that storage...except one: a versioned file system.

Anyone who's used source code control systems like CVS or Subversion should already know what I'm talking about. Basically, these programs create a file system that remembers everything that was ever done to it. So, every version of code developed along the way is stored, and if you mess something up, you can always just roll back to an earlier version. And because they store only the differences between successive versions, they remain quite compact considering what they do.

All versioning systems that I am aware of require periodic commits, or, that is to say, you have to notify the system that you have changed a file and have it save your changes to the versioned repository. But if you had enough storage, you could have the commits happen automatically, i.e. every time you do anything to your hard drive. Your drive would remember everything that was ever done to it.

You would never worry about corrupt files, accidentally deleted files, or messed up OS installations again. You would have a record of everything you had ever done on your computer...

Do you think such a thing will ever become practical?

When I was just out of high school, my best friend, who was definitely a computer geek, claimed that no one would ever need a Gigabyte of hardware space. I had a 100 megabyte HDD which was considered pretty big.

Currently the LAN where I live (2-3 people at any given time) has about 2 Terabytes of hard drive space. I doubt there is a Gigabyte of free disk space on the entire network, and we still have plenty of CDs, movies and applications that remain to be saved to the hard drive.

It won't be that long before a TB isn't considered much space.

Pretty interesting...it's quite amazing how technology has evolved over the years. It's just like the first amplifier...
