  1. how does the 5.25'' DD disrupt to 8''DD?
    • disk drive industry is the fruit fly in technology-high failure rate
    • initially 5.25'' DD cannot be used in the minicomputer 
    • 8'' DD were superior in terms of capacity, access time and cost/MB
    • 8'' DD manufacturer declined further development of 5.25''
    • Seagate introduces 5.25'' DD in the desktop PC market
    • by 1978 the capacity of 5.25'' DD has reached the capacity demand in the minicomputer market
    • 8'' DD and 5.25'' DD were in direct competition
    • 5.25'' DD was good enough, minicomputer makers started replacing 8''DD with 5.25'' DD
    • 8" DD makers like Shugart and Priam started failing
  2. why didn't 8'' DD makers react to the emergence of 5.25'' DD?
    • 8''DD has far superior capacity
    • PC market was not their core business
    • Advantage in existing technology, ie. 8''DD
    • developingn 5.25'' DD will hurt their 8'' DD business
    • due to the firm size, new entrants have higher incentive, like greater growth opportunities, in bringing disruptive technologies
  3. sustaining technologies vs disruptive technologies
    • improve products along dimensions that mainstream customers want
    • led by established firms, both incremental and radical
  4. disruptive technologies vs sustaining technologies
    • mainstream customers don't value them initially cuz they provide worse performance 
    • emerging market may value them
    • led by entrant firms
    • low margins

    • improve products along dimensions that mainstream customers want
    • led by established firms, both incremental and radical
  5. how firms avoid failure due to disruptive technologies?
    • upmarket migration of seagate product
    • sell DD with large range of capacity
