I don't think it's most people I think it's about half...![]()
Hmm, hard drive capacity doubles every year, and I'm pretty sure that most types of users haven't had their storage needs doubling every year during the past few years.
When simple text editing evolved to more complex word processing, it significantly multiplied storage requirements. When apps started using graphic interfaces instead of command line interfaces, it significantly multiplied storage requirements. When computers let you do low res black and white graphics editing and adding clip art into your word processing documents, it significantly multiplied storage requirements. etc... When CDs came out you could install much larger programs... When broadband came out people were able to easily download lots of music and multimedia files... When digital cameras out... When easy home video editing came out... etc.
But in the past 3 years, what major new computer-use change has happened that multiplied most people's storage requirements? The only major change I can think of that's happened to most people's computer usage over the past 3 years is that everyone is using "the cloud" now (gmail, google docs, netflix, hulu, youtube, Steam Cloud), all of which *decrease* the amount of local storage that most people need.
Sure, video professionals are now doing more HD editing, and other similar types of very small niche populations will have increased their storage needs over the past 3 years. But unless you can think of some other cause of a major increase in most people's local storage needs that I happen to be forgetting about, then this means that the vast majority of people have had their local storage requirements grow very slowly over the past 3 years, or maybe even shrunk.
