A good few years
ago now, I wrote the first Click article to focus on USB Flash Drives
and in it I rather optimistically sounded the death knell of the floppy
disc which at the time was still very popular.Of course, I also thought
the end was in sight when we were introduced to the rewritable CD, the
Zip Drive and the 120Mb Floppy, but let’s not dwell on these points too
much.The important thing to remember is that this time my prediction was
accurate and this is down, in no small part ,to the remarkable success
of the USB Flash Drive.
Despite
the widespread use of Flash Drives, I often still find myself giving a
crash course as many computer users as still unaware to what these
devices are and their potential benefits. A Flash Drive, or Pen Drive as
they’re often called, essentially consists of a memory chip encased in a
small piece of plastic with a USB connector on the front so that it can
be plugged in to pretty much any computer manufactured in the last
decade.All Windows Operating Systems afterMillennium Edition have the
necessary drivers installed as part of the Operating System so you
simply plug the device in to a spare USB port and immediately you will
be able to view all the stored files using Windows Explorer.
There
are many reasons why Flash Drives have become so popular of late and
these include, but are not limited to, their speed of operation, small
size, relatively low cost, high reliability and the amount of data that
they can store.
Whereas
the humble floppy disc can store a maximum of 1.44Mb the latest USB
Flash drives on the market will store 16GB of data which works out as
the equivalent of 11500 floppy discs being stored on a device that
weighs less than one single floppy.Additionally they are a great deal
faster and more reliable than their floppy counterparts and entry level
capacities of around a gigabyte will give you a couple of quid change
from a tenner.
Another
reason for their success may be because they don’t need any hardware
other than a spare USB port, system manufacturers were given the perfect
excuse to avoid having to install floppy drives in to every machine
they produced without limiting the potential for external storage.I’ve
had customers come in to our store, purchase a pack of floppy discs and
then return just half an hour later having found that their machine
doesn’t include a floppy drive – invariably they then purchase a USB
Flash Drive.
Windows
Vista now also presents a new incentive to those who were thinking
about buying a USB Flash Drive.To explain the benefits we first have to
look at a system known as Virtual Memory which is a technique used by
Windows in order to increase the amount of system memory available to
applications.Ever since Windows 3.0 which was released back in 1990, the
hard drive has been used in order to store any temporary files which
exceed the storage capacity of the system memory.This means that the
amount of memory available for the computer to use during operation is
practically unlimited.Unfortunately the hard disk is still a relatively
slow device because, unlike most other components that make up a
computer, it still relies on moving parts.A Flash Drive doesn’t have
such a constraint so if you plug one in to your machine whilst running
Vista it will volunteer to use any of the free space available as
Virtual Memory whilst still allowing you to use the device in the
intended fashion of a removable storage medium.Thiswill allow you to
squeeze a little extra performance out of your machine without having to
invest in any additional hardware.
