Secondary Storage

Secondary Storage

1. Optical Storage

   • Disadvantages
     • Not very durable so it can break extremely easy.
     • Has a limited capacity so when it runs out of space you cant store anything else
   • Advantages
     • Cost Effective and costs the least out of all the storage devices.
     • Very Portable and easy to distribute to several people.
   • Description
     • Any storage which uses CDs, DVDs and Blu-ray. These discs are read with lasers. It is less durable than magnetic storage.

2. Magnetic Storage

   • Description
     • Magnetic flat, circular plate called platters. These platters rotate at a very high speed. It is more durable than optical storage but less durable than solid state. It has a higher capacity to solid state but slower read/write speed in comparison.
   • Advantages
     • A fair price for what you get. Storage, read and write speed
     • Larger capacity than solid state so it can store larger amounts of data.
   • Disadvantages
     • Read/writes data slower in comparison to solid state which means it loads and saves slower
     • Not durable due to moving parts, this means it can break easily

3. Solid state storage

   • Description
     • Solid state storage is the most durable storage device out of the three. It has a high read/write speed but low storage.
   • Disadvantages
     • Has much smaller capacity than magnetic. This means it cant store as much as magnetic
     • Less cost effective in comparison to magnetic. This means it costs more than magnetic
     • Limited read/write lifespan which means its read/write capability can die out.
   • Advantages
     • Higher read/write speed compared to Optical and Magnetic storage.
     • Higher durability compared to Optical and Magnetic storage
