Secondary Storage

The choice of secondary storage medium depends on the use it is required for. When deciding on the type of device needed, a user should consider:

  • Cost - what is the cost per gigabyte (GB)?
  • Capacity - how much data can the medium hold?
  • Speed of access - how quickly can data be transferred to and from the medium?
  • Portability - how portable is the medium? Does it need to be portable?
  • Durability - how robust is the medium, and how robust will it need to be?
  • Reliability - how resilient and long-lasting is the medium?
