secondary storage

secondary storage

1. magnetic storage

   • example
   • example
     • seagate
   • advantage
     • this is a good price for the amount of storage due to having larger capacity compared to solid state
       • therefor it is cost effective
   • disadvantage
     • this is not as durable compared to solid state because magnetic storage has moving parts
     • this has a slower data transfer speed compared to solid state

2. solid state (flash) storage

   • example
   • example
     • SanDisk
   • advantage
     • solid state has a faster read/write speed compared to magnetic storage therefor, solid state will load programs and data much faster
     • solid state is more durable ( more likly to not break if you drop it compared to magnetic storage because there are no moving parts
   • disadvantage
     • solid state is more exspencive compared to megnetic state because there is not moving parts in a devise

3. secondary storage non volatile this means is a storage that stores your data permanently until you want to delete it

4. optical storage

   • example
     • BLU-RAY
   • example
     • DvD
   • advantage
     • optical stotage is very cost effected compared to solid state
   • disadvantage
     • opticall storage has a low campacity cpmpared to solid and megnetic state therefor you are limitted to how much data you can save
