SECONDARY STORAGE

1. solid state

   • examples
     • USB thumb drive
   • advantage
     • reliability
       • solid state is more reliable then magnetic storage because it has no moving parts whereas magnetic has ,moving parts such as spinning objects
     • portability
       • solid state is more portable then magnetic, therefor that its more portable then magnetic as its in your phone
     • read/write speed
       • solid state can run faster then magnetic therefore solid state is faster then magnetic as the read speed for solid state is 550 MB/s and the write speed is 500 MB/s. the read speed for magnetic is 159 MB/s while the write speed is 148 MB/s. its also got a better data transfer speed .
   • disadvantage
     • more expensive compared to magnetic as its more cost expensive because its more

2. optical storage

     • CD and DVD
     • WORM
     • BLUE RAY
