"Kryder's Law, a variation of Moore's Law, describes the trend 'magnetic disk areal storage density doubles annually'. In other words, you don't want to know how much I paid for a 40MB Seagate MFM drive in 1989, but today 1000GB drives rule the day for much less money. This increase in capacity follows a predictable trend.
"Conversely to Kryder's Law and Moore's Law (which basically describes computers becoming predictably faster), Wirth's Law states software becomes larger, more complex, and slower: in the end the win on one end is washed out by the loss of the other..."
