Hard Disks
A hard drive is a spinning platter that stores your data such as photos, music and other files in which your computer needs to operate. The SSD does the same programming with a set of solid state memory chips without any memory chips. An advantage of this is that the speed of rebooting your system or loading new programs is much quicker. Hard disks are measured in Gigabytes and Terabytes, typical hard disks range from around 120 GB - 3 Terabytes. A disadvantage of hard disks is that the disk it fitted inside the computer so it is not easy to transfer to another one.

Flash Memory Cards
These are small storage mediums which are used to store data such as text documents, audio and video Most of the current products use flash memory, although other technologies are being developed. There are a number of memory cards on the market, including the SD card (secure digital card), the CF card (Compact Flash card), the Smart Media card, the memory stick, and the Multi Media Card (MMC). Flash memory cards in different sizes and prices vary.

Tertiary Memory
A colossal source with numerous mass storage device in area which are mounted and dismounted by machines. Tertiary memory is used to store files in which are very rarely accessed as this will take time to get to them. When a computer needs to read information from the tertiary storage, it will first confer with a catalogue database to determine which tape or disc holds the information. Secondly the computer will guide a robotic arm to retrieve the medium and accommodate it in a drive. Lastly, when the computer has completed reading the information, the robotic arm will restore the medium back to its place in the library.
