Q

The three reasons why the type and specification of the mass storage drive is important

A
  1. If there is not enough space, fewer programs and data files can be stored on the computer
  2. If disk is not fast enough, performance will suffer if the computer tries to load programs and data files into memory
  3. The computer may use part of the hard disk to supplement system RAM (virtual memory). If the computer does not have much system RAM, it helps for the hard disk to be fast otherwise accessing virtual memory often will reduce performance even more than usual.
