Secondary Storage Year 8

Secondary Storage Year 8

1. Optical

   • Disadvantages
     • Has a smaller capacity than USB Flash Sticks or SD Cards. Therefore, it can store less data
     • It has a very fragile body and is not as durable compared to solid sate and magnetic storage. Therefore, more likely to break if dropped
   • Advantages
     • Is more cost effective than SD Cards or USB Flash Stick storage. Therefore, it is cheaper to buy
     • Can be used on laptops or PC's with CD players and DVD players. Therefore it is more portable than SD Cards and USB Flash Sticks

2. Magentic

   • Disadvantages
     • It is not as durable as Solid State Storage as it has moving parts. Therfore, it is more likely to break if dropped
     • It has a slower read/write speed than and Solid State Storage. Therefore, it will load data and write data slower
   • Advantages
     • It is more cost effective than Solid State Storage. Therefore, it is cheaper to buy than Solid State Storage
     • It has a higher capacity than Solid State Storage. Therefore, the user can store more files and data and can install less programs.

3. Solid State

   • Disadvantages
     • It has a smaller capacity than magnetic storage. So, the user can store less files and data and can intsal less programs.
     • It is less cost efficient than magnetic storage as it has a bigger price per GB than magnetic. So, it is more expensive to buy
   • Advantages
     • It has a faster read/write speed than and magnetic storage. So, you can load and store files/data the fastest
     • It is more durable than magnetic storage as it has no moving parts. Therefore, it is less likely to break if dropped

4. Secondary Storage is Non-volatile which means that the files on it are stored permanently
