Internal Hard Drive vs. External Hard Drive

Difference Between Internal Hard Drive and External Hard Drive

The Internal Hard drive and the External Hard drive are devices of storage used in the computer systems. A hard drive is the term used for the physical device which is a part of every computer used to keep data. This hard drive is essential for every computer system to accommodate the operating system, the files of program and data which is needed by the user. Every computer comes integrated with an internal hard disk which has different capacities from gigabytes to terabytes. Normally, this device is internal, but there is an option and a freedom for the user to use additional devices of storage which came to be known as the external hard drives.

Normally if the computer has enough space of storage, it does not need an external hard disk, but because of the threats of Internet to the data, many people began using these external hard disks. The external hard disks also give freedom to carry data from a place to other one and facilitate the sharing of data from a computer to other thus making it very popular. Many members of a family use the same computer system causing the threat of corruption in data involuntarily. Also the origin of HD video files meant that people need to keep huge quantity of video data in their systems thus requiring the external hard drive.

The external hard drives are similar to the internal hard drives and can be considered as a peripheral device which can be kept next to the computer and connected to the computer via a wire to facilitate sharing of data. There are such portable external hard disks with smaller capacities as iPods and pen drives which are especially used for the carriage of data rather than the primary purpose of storage of data.

The external hard drives not only allow the additional storage space; they also allow to the user to back up important data and programs so that in case of any accident of the system or the hard disk becoming corrupt these data can be retrieved. In such scenario, the user can have all important data and information kept in his external hard drive. You can keep all sensitive information on your hard disk as a back-up copy in the external hard disk. It is possible to turn off this external hard disk to protect it from any potential threats from Internet.
