        if component gets damaged stored data may be inaccessible
    - - disadvantage
        
        constant plugging wears the port down
        
        speed of access to the data is dependant on the USB connection
        
        limited number of reads
      - advantage
        
        low power consumption

  - - - too small or user to see and use
      - user can't see all of HCI and may not be able to touch an icon with finger
  - - - if the HCI has a lot of options, the file size needs to be bigger
    - - when a user interacts with a HCI, processing power is needed to complete he requested tasks
      - the more options the HCI has, the more processing power is needed which can mean
        
        less processing power to carry out other tasks
        
        responses to other tasks is slowed down
