Flash
Drives
by Chris Holgate
A good few years ago now, I wrote the first Click article to
focus on USB Pen 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. A Flash Drive is certainly a worthwhile investment and they are
available from all good computer stores including, of course, Refresh
Cartridges.
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
after Millennium 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 small size, relatively low cost,
high reliability, their speed of operation, and the amount of data that they can
store.
Whereas the humble floppy disc can store a maximum of 1.44Mb the latest USB
Pen 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 perk of the USB Flash drive is that they don't need any hardware to
work, so manufacturers no longer need to install floppy drives into their
machines. I've had customer come into the store to get some floppy drives only
to return shortly after having found that their machine doesn't have a floppy
drive. They generally then purchase a USB Flash drive instead.
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. This will allow
you to squeeze a little extra performance out of your machine without having to
invest in any additional hardware.
