Hard Disk Drives• Capacity varies from 20 Gb to 2 Tb.
• The read/write heads fly on a very thin layer of air on the disk.
• The closer the heads are to the disk, the narrower the magnetic track and hence the more data that can be fitted onto the disk.
Demonstration on how this works

Solid State Drives

• Disadvantage is they are more expensive that HDD.
