When did you first come across an external hard drive? Usually in a heavily fortified casing as fragile as eggshells it was a monster on your desk. An extra forty gigabytes memory for your computer is what, if you were lucky, you may have gained. Today's market in comparison allows you to carry mass amounts of storage in your pocket as long as it is not filled with change. External hard drives today are stronger, better performing and less expensive than when they first appeared in the 1980's.

An essential tool, an external hard drive is designed to give extra storage and using USB or firewire ports you connect them to your computer externally. They are an increasingly popular tool in today's modern and mobile age. Still prone to damage from knocks and vibrations, due to their construction, they are usually supported by a hard metal or hard plastic external casing.

There is a magnetised rotating disk within the hard drive casing that can rotate at a whopping seven thousand rpm. Prone to damage and decreased performance the disks are Just like a CD or DVD. Smaller discs in Laptops have fewer rotations per minute and this tends to lead to a decreased performance. Quoted in gigabytes or even terabytes, normally, we are a million miles from the megabyte age of zip and floppy disks. Increasingly decreasing in size hard drives continue to vary. In today's market with Mobile storage hard drives and pen drives you can basically take your memory anywhere.

The end of the external hard drive has been predicted due to the introduction of flash memory storage that most portable hard drives and memory sticks use. The fact they are still the lowest cost random access re-writable storage solution means this is yet to transpire. The drives that are probably most at risk from compact flash memory drives are smaller hard drives. Many companies have already invested in combining the magnetised disks with flash memory capabilities. The future lies in hybrid drives, and in their design.

It seems as if the external hard drive is here to stay for a little while yet. Although the advance in flash memory portable hard drives and memory sticks probably means they will need to find a new incarnation to continue apace with development. Otherwise they may well go the way of the floppy disk and tape cassette.
