Secondary Storage

Secondary Storage

1. Solid State

   • Advantage
     • It is more durable as it has no moving parts and its read/write data is much faster in comparison to magnetic therefore it will load quicker/faster
   • Disadvantage
     • It is less cost effective in comparison to magnetic as it has a much smaller capasity
   • Examples
     • Phone
     • tablet
     • Desktop

2. Is where you store data permanently which is non-volatile. it is needed in a computer system

3. Optical Storage

   • Advantage
     • Is that its prices are quite good (cost effective) and are portable compared to solid state therefore you can take it somewhere more eaisly
       • they are more portaible than solid state and magnetic devices therefore it can be used on other devices
   • Disadvantage
     • it has limited capacity and its not very durable therefore if its not very durable its more likely to break as it has some moving parts
   • Examples
     • DVD's
     • Blu-Ray
     • Cd's (ROM)

4. Magnetic

   • Advantage
     • It has a larger capacity compared to solid state and its very cost effective due to having that larger capacity
   • Examples
     • floppy disks
     • Hard drives
   • Disadvantage
     • It reads/writes slower compared to solid state. therefore it will load slower
