Introduction :A storage device may hold information, process
information, or both. A device that only holds information is a
recordingmedium. Devices that process information may either access
a separate portable recording medium or a permanent component to
store and retrieve data.Data Storage devices :

Magnetic hard drives :Working :
CDs & DVDs
Flash memory storage Micro SD cards & USB drives :
SD: secure digital
SD card :- secure digitalThe solid state chip inside the cards
plastic cover contains many tiny circuits. When card is not in use
circuits retain their charges with out additional power .When card
is placed in, a small electrical current from the devices moves
electrons,this digital pattern stored on chip correlate to the data
stored there. 7

Data storage technologies of future :5D data storage
5 dimensional (5D) digital data by femtosecond laser writing on
NANO glass.
Scientists at the University of Southampton have taken a major
step towards the development of digital data. Through the use of
nanostructure glass, they developed the recording and retrieval
processes of 5 dimensional (5D) digital data by femtosecond laser
writing.Their invention could be used to store data for up to 13.8
billion years. This technology was first experimentally
demonstrated in 2013 when a 300kb digital copy of a text file was
recorded in 5D.

Microsofts underwater data center
Microsofts Project Natick
an ongoing research project into sub sea data centers that could
be both, cost effective and environmentally friendly. They found
that placing data centers underwater not only helps keep their
contents cool but also has logistical advantages.The vast majority
of the Earths surface is covered with water and all international
fiber routes run along the sea bed. By deploying a data center on
the sea bed, you get around the issues with building a facility on
land and at scale, such as having to build away from major metro
areas where there is little fiber connectivity to keep land costs
low,11
Data Skyscraper
The tower is conceived as a giant 3D motherboard with a
cylindrical shape
Iceland has been recognized as an ideal location for data
centres. Moreover, since Iceland lies between the US and Europe,
companies could use a data centre located in Iceland to run web
services in both continents from a single place.Apart from that,
Icelands renewable energy could also power an energy-hungry data
centre cleanly and possibly at a lower cost and lets not neglect
the fact that Icelands cold temperatures could naturally cool the
servers thereby avoiding the costs of a traditional cooling
system.12
Hitachis waterproof glass disk
Hitachi plans to increase the amount of data that can be stored
while maintaining the optical characteristics of the glass.
Hitachi recently developed a technology which prints series of
dots upon a silver of quartz glass which can then be easily read
with a common microscope. This way, data can be easily accessed, as
well. Whats more? Data is safe from fire, chemical and water,
too.The chip measures 2 millimetres thick and 2 centimeters square.
4 layers of dots are put together, resulting in a data density of
40 megabytes to the square inch. The glass is stable under heat up
to 1832 degrees Fahrenheit13
Conclusion :Indeed, the types of storage devices mentioned are
not ubiquitous and widely used in present techno World
However, some of these devices may be required in certain
situations and increasing our awareness about how these devices
work and their uses may enhance the efficiency in the workflow of
the situation. Nevertheless, the drawbacks derived from some
devices cannot be overlooked.
We have to be careful in selecting the types of storage devices
we wish to employ for a certain task so that we are not encountered
with undesired consequences which may or may not be reversible.
