Secondary Storage: Mind Map

Secondary Storage: Mind Map

1. Solid State

   • The Solid State has the fastest read/write speed. Therefore, it is the complete opposite of the magnetic storage and the programs will load quicker.
   • It has lower capacity so you are unable to keep loads of data on it.
   • USB
   • SSD disc

2. Optical Storage

   • It is less durable, so it would be easier to damage or break.
   • It is non-volatile, which means that the data on the disc is going to stay on there permanently.
   • CD
   • DVD

3. Magnetic Storage

   • High Capacity - it is able to store a lot of data.
   • It's got the slowest read/write speed, therefore the programs will load slower.
   • Floppy disc
   • Hard Drive

4. Is non-volatile storage. It is needed in a computer system to store your programs, operation systems and files.

   • Non-volatile means that the data is not deleted when the computer system has no power connected to it.
