Secondary storages

Secondary storages

1. Secondary storages are non-volatile storages which means that they keep data stored permanently, even when the device is turned off. This is useful when games started to become longer and couldn't be completed in one day, therefore needing save points. The data can only be removed/deleted if the user says so.

2. Solid state storage

   • Examples
     • USBs
     • Microchips
   • Advantages
     • Energy efficient (more cost effective) than optical storage.
     • Faster read/write speed than magnetic storage.
     • More durable than magnetic storage: it has no moving parts.
   • Disadvantages
     • Has a limited read/write lifespan.
     • Less cost effective compared to magnetic storage.

3. Optical storage

   • Examples
     • CDs
     • DVDs
     • Blu-Ray
   • Advantages
     • It is cost effective (compared to solid state and magnetic).
     • It's very portable because it's light and quite small.
   • Disadvantages
     • It has a limited storage capacity.
     • Not very durable compared to magnetic and solid state.

4. Magnetic storage

   • Advantages
