Secondary Storage

Secondary Storage

1. Magnetic

   • Advantages
     • High Capacity{lots of storage space}.This is diffirent to Optical because they have a small amount of storage space
     • Cost Effective {does not cost much}
   • Disadvantages
     • Less durable then solid state and can break easily

2. Solid state

   • Advantages
     • High read write speed
     • Durable {it has no moving parts} unlike magnetic which has more moving parts
     • Energy efficient {runs with less energy}
     • Reliability{trust worthy and has fast read write and speed}
   • Disadvantages
     • Not as cost effective{expensive and is cost more}

3. Optical

   • Advantages
     • Cheap {not pricy}
     • Portable {can be taken around} unlike Magnetic which can not be carried around because of its moving parts
   • Disadvantages
     • Can be scratched and broken which proves its not durable unlike solid state which has more durability and protection
     • Small capacity {not much storage space}

4. Purpose

   • What do we use storage for?
   • Storage data {files application}
