Solid State Drives In Windows Vista
Want to logon Vista using flash drive? Vista flash drive has definite advantages.
Computers store information in floppy drives…
These were the words which we heard during 1980’s.
As the technology kept growing, the large storage medium
came into existence. The large storage medium changed
the way of using the computers. Floppies stored information
in terms of Kilo bytes. Later on, floppies started to
store in terms of 1.44 mega bytes when 3½ Floppy
disks introduced.
The need for larger storage devices had led to the
development of Hard disks. Hard disks became popular
storage medium, because, it can store both programs
and other information on a single disk drive. It soon
became a permanent storage media for computers. The
introduction of CD-ROM (Compact Disc Read Only Memory),
led to the replacement of floppy disks in backup media,
because the CD-ROM’s can store the data nearly 400 times
more than the floppy disks.
This led to the development of more versatile media
called DVD-ROM. This enabled storage of up to 2 G.B
in a single disk. Hard disks, CD-ROM, DVD-ROM, were
found to be slower because, the speed to access information
depends on the rotation speed of the motor that is mounted
in these drives. So, the need for a high speed drive
came up.
Flash drive for Vista - Non Volatile Data Storage Device
Solid state drive is a data storage device, which makes
use of non volatile memory such as flash and volatile
memory such as SDRAM, to store the data, instead of
spinning platters which are found in hard disk drive.
Technically speaking, Solid State Drive is not actually
a disk, but, can be used as replacement for Hard disks,
when the use of conventional drive slows down the systems
performance. SSD’s are 250 times faster than the
conventional hard disk drives. It is used to boost up
the application performance. The nonvolatile nature
of flash memory makes data to remain in the event of
power failures. Flash SSD’s are faster in nature
which eliminates seeking time (Seek Time), latency,
and other electro-mechanical delays which exists in
the conventional hard drives. The SSD’s are usually
commonly used in computers wherein, the conventional
RAM limit is full. In such situations, the SSD acts
as additional memory in these systems. For example,
if the maximum amount of memory allowed in the system
is 4 GB, then, programs make use of virtual memory concept
by creating swap files normally in the Hard disk. Instead,
one can make use of SSD’s instead of much slower
hard disk. Virtual memory is the logical illusion of
very large memory. The main memory contents are swapped
with the portion of disk swap file contents, as and
when required. This concept is used in Windows Family
of operating systems, as it requires very large memory,
which some of x86 architectures do not support. Even
if it supports, the user cannot purchase such a large
physical memory modules and install them in his system,
because, the RAM modules are very expensive. SSD’s
are smaller in size and is of lesser weight compared
to that with Hard disk drives.
Windows Ready Boost
Now days, there are very different kinds of SSD’s
are made available from different manufacturers. The
maximum capacity varies from 4 GB to 16 GB and so on.
One can increase execution speed of the programs by
storing the hard disk data, into the SSD’s which
enable faster swapping. Some SSD comes with Windows
Ready Boost, the Vista feature that uses flash memory
technology which increases system performance when compared
to swapping performed with the support of hard disk
drive. Data seek delay is also eliminated because, the
SSD’s serve nearly 5000+ requests, which is 100
to 200 in case of Hard disk drive. SSD’s often
work with hybrid drives which are the secondary source
of cached data. The growth of technology will see the
rise of SSD’s with more capacities which is just
like any hard disks or even more than that. SSD’s
are gaining more importance and hopes to replace hard
disks in the near future, getting recognized as a reliable,
high-density, powerful data storage medium.

place, when one switches ON the computer. As soon as,
the computer is switched ON, entire computer gets power.
