Storage Devices

Storage Devices

1. Solid State

   • These devices are mainly used for computers
     • The solid state hard drive features HDD and SSD
       • They are combined into one unit
   • Advantages
     • They are faster than hard disk drives
     • Longer battery life
     • More resistance to bumps and falls
   • Disadvantages
     • Most expensive
     • Complex design
     • Small storage capacity

2. Magnetic

   • The magnetic storage devise uses different patterns of magnetisation in a magnetisable material to store data
   • Advantages
     • It is a popular type of magnetic storage
       • It's a floppy disk
         • They are easier to handle
   • Disadvantages
     • It's slower to find data
     • It's susceptible to physical damage
     • It's difficult to recover after damage

3. Optical

   • Optical storage uses low power beams to record and retrieve digital data
     • In optical storage, a laser beam encodes digital data onto an optical or laser disk
   • Advantages
     • Low cost per bit of storage
     • Long media life
     • High data stability
