We don't pretend to attract too many readers who were around when IBM unleashed their model 350 hard disk in the RAMAC some fifty years ago. So you regular, mild-mannered geeks probably aren't aware that the original magnettic spinner featured no less than 50, 24-inch platters for a whopping (at that time) 5MB of storage. Why 24-inches? Easy, the disk was engineered to be "small enough" to fit through a standard door frame! My my, how times have changed. Today we're squeezing 12GB of storage into Jetsonian 1-inch drives while Seagate merrily stuffs a full 750GB of perpendicular goodness into a 3.5-incher. And with drive capacities effectively doubling every two years, it comes as little surprise to hear a product VP from Hitachi predicting a 3.5-inch drive sporting 1TB (1,000GB) before the year is up. Still, it's always good to get the poop direct from the source, so to speak.
