   • External hard drive
   • Playstation memory card
   • USB memory stick
   • Excellent read/write speed
   • Not good capacity (doesn't store as much data) compared to magnetic storage

3. Optical

   • CD/DVD/Blue Ray

   • Not very durable can be scratched and breaks easily

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

   • Non-volatile means that when the computer is turned of or has no power connected to it the programs will not be deleted
