Hard drive and SSD

A hard drive stores all of the data which isnt in use at the moment. It contains moving parts which means that when it gets shaken it breaks, which is a major disadvantage and also it is rather large.

The SSD is a smaller version of a hard drive and it doesn't break when shaken. It also is alot faster but are more expensive.
