secondary storage

secondary storage

1. optical storage

   • Blu-Ray
   • DVDs
   • CDs
   • Optical storage is not very durable therefore it can scratch and break quite easily.
   • In comparison you should use solid state because, it is durable which means it wont break as easy.

2. Its 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 has no power connected to it.

3. Solid state (flash) storage

   • microchips
   • magnetised disks
   • Solid state (flash) storage is the most durable
   • solid state (falsh) is less cost effective and it has a slower read and write speed compare to magnetic

4. magnetic storage

   • floppy disk
   • hard disk
   • High capacity (stores a lot of data) compared to optical storage
   • Not as durable due to it having moving parts
