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.

There are two primary types of external hard drives; flash based and enclosed mounted disks. The latter rely on moving parts and as such are susceptible to skipping when bumped or jarred. These are becoming outdated and overlooked by consumer in favor of the former, flash based drives. These have no moving parts, are more compact in size and have come to offer larger storage capacity. They do, however, come with a higher price tag.

Flash based drives are smaller than mounted disk style drives and have internal moving parts. These solid state devices use USB or Firewire connection cables to interface with the computer. Through this platform, any newer PC can connect to the drive regardless of operating system. Solid state memory currently top out at around one to two terrabytes for the more expensive models.

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.

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.
