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).

It is absolutely necessary to secure your data which is your valuable asset. In the 1990s, people can only store data in the disk internal (internal hard disk) which capacity only 100 MB is not enough for today, and store data in external media using 1.44MB floppy disk as the only choice, which has a slow data access, easily damaged so it’s not safe for your data, and its small capacity requires many floppy disks to store large amount of data.

Recently, all of the old technology has been forgotten since disk external (hard disk external) is invented. Even now, disk external capacity is larger than disk internal capacity and its capacity increases rapidly because of people’s needs these days. Today, the largest capacity for this kind of product is 8 TB which can be used for small business as server.

Disk External Secures Your Data

Your data will be more secured if stored in hard disk external because it can be easily carried, can be accessed on another computer, more easily secured in disaster, and some external disk have a solid structure for impact resistance. Stop back up your data on internal hard disk because it is hard to be secured within disaster, mechanical failure due to short circuit or high temperature, and virus attacks.

Disk external is divided into 2 types, namely portable external hard drive and external desktop hard drive. Portable external hard drives have a lower capacity than external desktop hard drives but it is smaller in size, so it can be put in pocket and wallet. Now, most people prefer to use external desktop hard drive to store data than using internal hard drive because it is not easily to get hot, easy to be taken handy, and also has a better performance.

To back up your valuable data on external hard drive is a good idea. Adjust the capacity with your needs although I recommend purchasing a larger capacity with the best specifications for future purpose.
