Most models are little and
easy to transport, they only weight around
250 to 300 grams and are resistant to hits
and scratches, as well as to dust and water;
these makes them superior to other storing
devices such as floppy discs, compacts discs
and DVD.
These devices were created in 1995 by IbM,
as an alternative to floppy discs. Even
though they were created by IbM, they did
not patent it, they would do it only later
with the aid of M � Systems, who helped them
to finish developing it. |

The first
Flash units were only from 8 Mb, 16 Mb,
32 Mb, 64 Mb and 256 Mb, they temporary
replaced floppy discs; nowadays, flash units
go over the 180 Gb of storage and easily
replace a little hard drive. |

We must also remember that
the
USb units have speeds, which is a very
important characteristic; the first devices
used to work at a 1.5 Mbit / s or 12 Mbit /
s, but little by little, due to their
evolution, its speed reach up to a 480
Mbit/s speed, doing that the process of
storage and copying to take only a few
seconds. Currently, there are works to
increase even more the storage and speed
capacities. |

Even though at first they were not very popular,
nowadays, these portable devices are found among the most used
one, and many models have been created with a variety of
capacities which start from 1, 2, 4, 8 Gb up to 64, 128 and 200
Gb.
Their popularity has give them an infinity of denomination,
as well as the design of its shape, been none of them definitive
in managing to reach is regular form, a little rectangle.
Naming it
USb has been the easiest way to refer to
this storage device. |

Regarding the current
operative
systems, all of them can detect,
read and write on it, by simply plugging it
on the USb entrance on the equipment, this
device is activated when receiving energy
from the USb connector. However, in
posterior Windows,
GNU / Linux
or MaC OS
versions, you need to install a
device controller provided by the
manufacturer.
Despite the fact that these devices have
many advantages regarding their price and
storage level, they also have many
weaknesses in their functioning. Among the
reasons for these weaknesses we can see that
they can stop functioning for various
reasons, like, for example: voltage changes,
falling from great heights, excessive usage
for long periods of time, and they can also
have
viruses, and by simply plugging
them into our computers we might be
infecting it.
at first, this device was designed to store
data and text documents, meaning only work,
nowadays it is very common to find it with
program information,
MP3
music, images, etc. The newest devices in
the market will have an LCD screen in which
a menu can be opened up and it will have
different files in which we can store are
data; also, its transference speed will be
10 times faster than the current ones,
hitting the 4.8 Gbit per second. Little by
little we will see the evolution of the
storing devices which is changing the way in
which we store our documents, let�s only
hope that it can be used and acquired by
anyone.
