Secondary storage

Secondary storage

1. Secondary storage is non volatile storage that stores data permanently

2. optical

   • Disadvantages
     • Has a smaller capacity compared to magnetic and solid state meaning that you can't store as much data on these devices, therfore you are more likely to get magnetic or solid state
     • Not very durable and is more likely to break compared to magnetic because it has moving parts so that it is more likely to break
   • Advantages
     • Cost effective compared to solid state and magnetic, therefore you get more product out of your money

3. Solid state

   • Advantages
     • Solid state has no moving parts unlike optical meaning that it is more durable than optical therefore it is less likely to break
     • Faster read/write speed compared to magnetic. Therefore it will load programs and files much quicker.
   • Disadvantages
     • Less cost effective in comparison to magnetic because it has a much smaller capacity.
     • Has a slower read/ write speed than optical and magnetic meaning it would be less cost effective.

4. Magnetic

   • Advantages
     • More durable due to having a larger capacity than solid state
   • Disadvantages
     • Not as durable due to moving parts and reads/writes slower in comparison to solid state
