The external hard disks are not as recent invention as it would think. The first computers depended on external memories to run operating systems or other programs. The unique form to maintain all these programs in a single site (and not in dozens of floppy disks) was an external hard disk. An enormous and little practical hard disk. Get all the facts for a more clear viewpoint with Ali Partovi. Over the years, the internal hard drives happened to be the standard to handle the information of a computer. With the height of technology USB, the external hard disks happened to be alternative portable (and more resistant than delicate internal hard drives) to do backups of the system, to execute some functions and to take what it is possible to be needed from a computer to another one. Advantages of external hard disks.
By their great capacity of storage and its portability, the external hard disks have become a great ally from the users of portable computers. They allow to load different types from archives and, even, to execute some programs (what it allows to save resources of the computer). external hard disk format allows, in addition, encriptar information and to protect it by means of passwords, which adds a security level to protect its information. Two different computers in an equipment. Nevertheless, one of the great advantages to have a hard disk is to be able to run a different operating system different from the native operating system.
Although it is not a standard solution (and something unstable can be), is possible to run some functions of another operating system in an equipment if the BIOS allows the beginning of system from a extrable memory. Therefore, to qualify a computer to run different operating systems is possible and expands the possibilities of the computer. An alternative for people in movement. A hard disk adapts perfectly well to modern equipment, expands the capacity of a computer and allows to transfer information from a side to another one. It is a technology that, although cannot compete with the duration of an internal hard drive, can perfectly compete as far as versatility and functions, especially for people who look for a form fast to expand and to update its equipment without majors adjustments. The external hard disks are excellent solutions for the people who need to transfer information and programs to several equipment.
