Basics Of External Hard Drive
External hard drive have become a useful and almost necessary addition to many personal computer. A few points should be considered when using or buying one of these units.
The two main types of external drives are mounted disk and flash based. Mounted disk style drive are similar in nature to the hard drive internal to a PC. It contains rotating plates on which data is recorded. The speed of revolution determines the rate of data transfer. These have upwards of a two terrabyte storage capacity (2,000 GB) and can be about the size of a book. The mechanical nature of these makes them difficult to transport.
The drives are physically separate from the body of the PC. Modern models connect via Firewire or USB 2.0. This format allows the drive to be used with most current operating systems.
The drives are designed to store data. In many cases this can include programs that operate on the PC to which the drive in connected. Applications installed on external hard drive will have portability issues unless they are configured to leave no finger prints and work dynamically with whichever PC they are connected. Many free portable versions of applications are available online through various sites.
Media files have become ubiquitous amongst file servers. The demand for more and better entertainment has led to very large storage capacity needs. Before a person realizes, their computer can be overrun with mp3 and wmv files that take their toll on the performance of the system. By moving these files to the external drive, the system’s ram and virtual memory will be freed to accomplish other necessary commands and improve the performance of the system.
Viruses are a danger to keep in mind with any file transfer situation. Portable virus scanning software are a great idea for thumb drives and external hard drive. Incoming files are scanned for infections and the user is warned. Aside from this, always keep your anti-virus ware up to date.
