secondary storage

secondary storage

1. it is non-volatile storage. it is needed in a computer system to store programs, operating programs and opening files

   • non-volatile means that the data is not deleted when the computer system has no power

2. solid state (flash) storage

   • it is more durable and can read and write data much faster than magnetic storage
     • it is also more energy efficient
   • limited read and write spam
     • smaller capacity compared to magnetic

3. magnetic storage

   • larger capacity compared to solid state
     • cost effective
   • moving parts make it not a durable
     • read and write it slower compared to solid state

4. optical storage

   • optical storage is cost effective and very portable
   • not very durable and has limited capacity
