Secondary Storage

Secondary Storage

1. Magnetic storage

   • Its cost effective compared to solid state,this is due to larger capacity.Therefore it costs less
     • Has a larger capacity compared to solid state therefore it will store more data/files
   • Not as durable as solid state due to moving parts
     • Has a slower read/write speed compare to solid state therefore it will load/save data/files slower
   • Seagate 3TB HDD,Floppy disk

2. Solid state

   • Higher read/write speed compared to magnetic storage therefore it can load and save faster
     • More durable compared to optical storage therefore it doesn't get scratched/damaged easily
   • Less cost effective compared to magnetic due to lower capacity
     • Has a smaller capacity compared to magnetic storage therefore it will store less data/files
   • SanDisk SSD,

3. Optical storage

   • More portable than magnetic therefore you can carry it out easier
     • Not very durable unlike solid state therefore it will get scratched/damaged easily
       • Has a limited capacity unlike magnetic therefore it will hold less amount of data
     • More cost effective than solid solid therefore it will cost less
     • CD,DVD,Blu-ray

4. Non-volatile

   • It is needed in a computer system o store your programms

5. Volatile

   • It deletes programs when the computer is switched off
