One of the reasons that the iPod is so popular is its sleek and simple design and easy to use functionality. Most people love the features of the iPod which can be attributed to specific components of hardware. They include storage, battery and click wheel.

Storage

Miniature hard drives can be smaller than 2 inches and fit as much as 80 gigabytes of data, making it extremely easy to store your entire music collection and download several full length motion pictures. On smaller sized units such as the iPod Nano and iPod Shuffle a different type of storage media is used, it is called flash memory. This type of storage unit usually holds from 1 to 8 GB of data. The advantage of using flash memory is that it is even smaller than miniature hard drives and extremely thin, allowing an even smaller device to be created.
