Secondary Storage

1. Optical

   • Examples
     • CD
     • DVD
     • Blu-Ray
   • Advantages
     • More cost effective compared to solid state
     • More cost effective compared to magnetic
   • Disadvantages
     • Less durable compared to magnetic
     • Less durable compared to solid state

2. Magnetic

   • Examples
     • Hard disk
   • Disadvantages
     • Less durable compared to solid state meaning it's far easier to break and less portable
     • in comparison to solid state it has a slow read write speed, so it's also less reliable
   • Advantages
     • More cost effective compared to solid state as it has a larger capacity
     • can be used in a school server for very cheap

3. Solid state

   • Disadvantages
     • Less cost effective compared to magnetic storage
     • Less cost effective compared to optical
   • Advantages
     • More durable compared to magnetic storage
     • Faster read/write speed compared to magnetic and optical
