I was reading this Computerworld article about a dentist who uses an iPod to back up his patient data, and starting thinking…
Everywhere I walked in New York, I saw white earbuds in people’s ears. Subway crime in New York would be down slightly this year, except for the rise in theft of iPods, which pushes the stats up 10%.
Apple shipped 5,310,000 million iPods in the first quarter of 2005, up 558% from last year. Yes, that’s right, more than 500% higher than last year.
Around Christmas, they sold 4.5 million iPod music players, up 525% from last year’s holiday season.
That compares to 5.7 million iPods in total up to 4th quarter of 2004.
So in total, there’s now 15 million iPods sold.
I have a first generation iPod. It holds 5 gigs of data, and I still use it regularly. I had to replace the battery last year, but it still trucks along. It’s safe to assume that most of the iPods sold are still in use.
So, I’ve put together a quick estimate, and I figure there’s about 229 petabytes—229,000,000 gigabytes—of storage space floating around on iPods. That’s pretty amazing.
But what’s most amazing, is that there were 300 million Sony Walkmans sold during the 80s-90s. Even ignoring the increase in storage size that will happen in the next 10 years, if iPods catch on like Walkmans, we’re talking 4.44 exabytes—4,438,000,000 GB—of data storage on iPods.
As my math teacher used to say, “This begins to get interesting, no?”
“I find myself thinking of a checklist Wozniak wrote a few years ago describing how to become a genius. His advice was straightforward yet strangely terrible: You must clarify your goals, gain knowledge through spaced repetition, preserve health, work steadily, minimize stress, refuse interruption, and never resist sleep when tired. This should lead to radically improved intelligence and creativity. The only cost: turning your back on every convention of social life.”
“Twenty years from now you will be more disappointed by the things you didn’t do than by the ones you did. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream.”
That is a very interesting exercise - I'm especially impressed that you know what the word "exabyte" means (or that it even exists!) I'd have to say you probably skewed it a little too far toward the iPod "white" and undercounted the Mini, so your total storage might be a little high. In any case, that's a hell of a lot of space.
the only thing that i might suggest fixing to improve would be the format of the page. i think it would be better to have it scroll down (like a normal page) as opposed to horizontally.
You can scroll right easily by holding down the SHIFT key and using your scroll wheel. (Firefox users trying this will end up jumping to old Web pages until a) Firefox releases a fix, b) they change their settings like so.)
