Data storage has always been a key issue in the world of personal computing. External hard drive have grown to become a vital PC tool. Some factors should be known when using or buying these items.
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.
In some cases, programs even operating systems can be installed and run from the drive through the connected computer. However, unless the programs leave no finger prints, there may be portability issues. The program will generally only run on the PC to which the drive was plugged in. Applications can be reconfigured to leave little or no finger prints, which allows the program to run on multiple machines. There are many web sites that list quite a few portable version of commonly used applications that are open source and free.
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.
Many people prefer digital format for their CD or DVD collections. Condensing these large volumes into one easily organized unit is a time and physical space saver. However, media and file sizes have increased considerably in the last decade. External hard drives have become almost a necessity to store all video, audio and production files. Using an external hard drive, frees up memory available on the source computer, allowing the PC to run faster with virtual memory enabled.
