Storage Devices!

1. Solid State!

   • It is found in:
     • Phones!
     • Tablets!
     • USB Sticks!
   • It has no moving parts!
   • Advantages:
     • High read write speed.
     • Energy efficient.
     • Durable.
   • Disadvantages:
     • Not as cost effective.

2. Magnetic!

   • The hard disk inside your PC or laptop is probably magnetic.
   • Advantages:
     • High capacity.
     • Cost effective.
   • Disadvantages:
     • Less durable than Solid state.

3. Optical!

   • Optical storage uses a laser to read and write to CD's, DVD's and Blue Ray's.
   • Advantages:
     • Portable.
     • Cost effective.
   • It can be used in many devices.
   • Disadvantages:
     • Not durable and can be easily scratched.
     • Low capacity.

4. What is storage?

5. Purpose

   • What do we use storage for?
     • Storing data ( files operating system applications ) permanetly.

6. FUN FACTS!

   • Magnetic is more cost effective than solid state.
   • Solid state is more durable than optical because CD's can be scratched easily.
   • Magnetic is less durable than solid state because it has moving parts and can be broken easily.

7. FUN FACTS!

   • Solid state has a lower capacity than magnetic.
   • Solid state has a better read/ write speed than magnetic because there are moving parts in magnetic.
   • Optical is more cost effective than solid state.
