Secondary Storage

Secondary Storage

1. Optical Storage

   • Advantages
     • Low cost compared to Magnetic and Solid State which therefore makes it easier to get your hands on
     • Optical storage is very portable compared to other devices therefore making it the easiest to transport
   • Disadvantages
     • Optical storage is very easy to damage compared to Solid state and Magnetic storage therefore it's not very reliable
     • Optical has a limited storage capacity and it's a lot smaller compared to both Magnetic and Solid State therefore rendering them useless compared to the other devices

2. Solid State

   • Advantages
     • Faster read write-speed compared to magnetic storage which makes it the fastest storage type. Therefore it runs programs quicker
     • Extremely durable compared to other storage devices which makes it less easy to break
   • Disadvantages
     • Expensive compared to other storage devices therefore makes them hard to get
     • not very portable compared to optical storage. Therefore making it less easy to move around.

3. Secondary Storage is devices that store data permanently until it's deleted

   • This makes the storage non-volatile

4. Magnetic Storage

   • Advantages
     • Very cost effective as they have the largest capacity for the cheapest price therefore making them better than the other storage types
     • Magnetic Storage uses magnetic plates that rotate which makes the storage faster than Optical storage. Therefore magnetic storage is the middle ground of storage
   • Disadvantages
     • Due to the moving parts, it can wear down so comparing to Solid State. Therefore making it less effective as it can break easier
