Hard disk is a computer hardware which is used by computer users to store applications, programs, images, mp3 files, videos and many more. There was just one kind of hard disk before, namely hard disk internal, but with the growing needs and demand, hard disk external has been invented.

Recently, the needs of data storage capacity increase dramatically and the demand in terms of efficiency also increases, i.e.: the data can be taken handy and can be accessed anywhere. Therefore hard disk external is the solution for those needs and demands. One advantage of hard disk external is its efficiency to operate. If you want to use it, just plug in the USB port and it can be revoked any time even when the computer is still used. This hardware can be easily secured within disaster such as in fire and flood, because of its lightness and small size. It can be a tool to backup data if the computer’s performance slowed due to the full hard disk internal storage or another problem.

It is connected to the computer through the USB port. Usually USB port is located on the CPU, at the front-bottom and at the back of the CPU. Hard disk external has a wide variety of storage, and the storage capacity of hard disk external reaches 500 GB, even 8 TB (for example: Seagate BlackArmor NAS 440). Hard disk external also has a variety of data transfer speeds for back up purpose, spindle speed (RPM) for data access speed, and Buffer cache size for used file temporary storage (allows fast access for used file).
