1. magnetic

   • Advantages
     • cost effective compared to SSD (if you need storage) therefore reducing cost on computer hardware
   • Disadvantage
     • It's not very durable compared to ssd which means if you drop it its has a higher chance of breaking when it contacts the floor. this means its not very cost efficient.

2. Secondary storage is a non-volatile device which stores data permanently

3. Optical

   • Advantages
     • Very cost efficient so you are paying the right amount of money for the storage system
     • Can be used to easily used to distrubute data
   • Disadvantages
     • It can get damaged very easily compared to solid state as it needs moving parts in order to read/write it's contents so if it falls or gets dropped then it will get scratch or break

4. solid state

   • disadvantage
     • It has a lower capacity than magnetic so it wouldn't be very helpful if you had loads of documents that takes up a lot of space
   • Advantages
     • Has no moving parts compared to optical and magnetic storage which means it is less likely to get damaged
     • Has a quick read and write speed compared to magnetic so that you are more time efficient therefore you won't have to wait for ages for things to load
