Storage Media

There are many devices that are capable of storing digital information such as Flash drives and CD drives but most fall into one of three types.

There are three main types of storage media:
 * Magnetics- This is the current standard for main storage with Hard Disk Drives as it is high capacity at lower costs. You are able to Read/Write to the drive to change data as you please. Magnetic storage works by storing data using magnetic fields on magnetisable surface such as HDD platters or magnetic tape.


 * Optical- Data is burned onto a disc by using a laser, making it read only once it has been burnt. The most common optical media is CD/DVD/Blu-Ray disks.


 * Flash- It stores data on EEPROM. Data is stored in memory cells that can be either read or written to. It is faster than magnetic and optical drives as there are no moving parts although cost more. It is commonly used in USB Flash Drives and Solid State Drives.
