A Hard Drive stores all the information of your computer. It saves your files and data. You can also use a SSD (Solid State Drive) which is the same thing but is smaller, has no moving parts and more expensive. It is used in an iPhone, iPad etc. An SSD card is used more nowadays because it stores more information, fits in smaller things and is quicker to use.
