Secondary Storage

Secondary Storage

1. Magnetic Storage

   • Magnetic Tape
   • Floppy disks
   • High Capacity
   • Not as durable due to moving parts
   • Cost effective due to having a larger capacity than solid state.
   • reads/writes data slower in comparison to solid state.

2. Solid State (flash) storage

   • USB STICK
   • SSD
   • More durable and can read and write data much faster than magnetic storage.
   • It is also more energy efficient.
   • Less cost effective in comparison to magnetic because it has a much smaller capacity.
   • It also has a limited read/write lifespan.

3. Optical Storage

   • CD
   • DVD
   • limited capacity
   • Not very durable
   • Cost effective
   • Very portable

4. It is non-volatile.it is needed to have a computer system to save your programs, operating systems and files

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