Any serious computer user already knows that this thing called an external hard drive, has great potential for practical uses. So how do you want to apply this tool for your best advantage or do you want to have more than one type or size to use for different tasks?

For example; do you want to play “James Bond” and have miniature flash drives in your pocket, carrying “Top Secret” information or perhaps you want to have a full size external drive standing beside your computer for extra storage space or to use for full system backups?

A flash drive consists of a small circuit board carrying the electronics and a USB connector. The board is protected inside by a plastic, metal, or rubberized case which can be carried in a pocket, purse or on a key chain, for example. The USB connector is generally protected by a removable cap or by retracting into the body of the drive, although damage is rare if unprotected. Most flash drives use a standard USB interface allowing you to plug the flash drive into a port on a laptop or desk top computer, but other interfaces are available if necessary.

The architecture of the flash drives will allow for multiple read/write functions. Some of the tiny drives will maintain data for as long as ten years. For the old timers, you know that is a long time to hold data secure!

The larger more standardized external hard drives (the ones that spin platters while the read/write function takes place) are just like the drives that are inside your computers. They record your information by applying a charge across the magnetic media that is ’stuck’ to the metal disk(s). They are compatible with all operating systems and are connected to your computer or laptop by standard interfaces such as USB or other cables, interfaces and embedded devices that come with your computer. The external hard drives can be attached to a main server, your computer or even a laptop. These are extensions of the hard drive within your computer.

External hard drives can be used as another ‘lettered’ drive whenever you use your machine. If you do not want anyone to have access to the information that you have stored on the device, do not power it up. Simple enough, you maintain control of the flow of information to and from your external hard disk add-on.
