Secondary storage

Secondary storage

1. Solid state

   • It doesn't have any moving parts so solid state storage is very durable, which means that it doesn't break very easily compared to magnetic storage, which has moving parts.
   • It isn't very cost effecive, which means that it is expensive to buy compared to optical storage, which is cost effective.

2. Magnetic storage

   • Cost effective due to having a larger capacity than solid state.
   • Not as durable due to moving parts and reads/writes data slower in comparison to solid state.

3. It is non-volatile storage. It is needed in a computer system to store your programs, operating system and files.

   • Non-volatile means that the data is not deleted when the computer system is turned off.

4. Optical storage

   • Cost effective and very portable compared to solid state.
   • Not very durable and has a limited capacity, wheras solid state is very durable and magnetic storage has a high capacity.
