Some information about Solid State Drive

If you are looking at a modern laptop, you will likely see some
that come equipped with a solid state drive. This form of
computer storage has been on the market for some time but only
recently has been embraced by the industry and consumers as a
viable alternative to traditional hard drives. So, what exactly
is a solid state drive (SSD) and how does it compared to a
traditional hard drive?
What is a Solid State Drive?
Solid state is term that refers to electronic circuitry that is
built entirely out of semiconductors. The term was originally
used to define those electronics such as a transistor radio that
used semiconductors rather than vacuum tubes in its
construction. Most all electronics that we have today are built
around semiconductors and chips. In terms of a SSD, it refers to
the fact that the primary storage medium is through
semiconductors rather than a magnetic media such as a hard
drive.
Now, you might say that this type of storage already exists in
the form of flash memory drives that plug into the USB port.
This is partially true as solid state drives and USB flash
drives both use the same type of non-volatile memory chips that
retain their information even when they have no power. The
difference is in the form factor and capacity of the drives.
While a flash drive is designed to be external to the computer
system, an SSD is designed to reside inside the computer in
place of a more traditional hard drive.
So how exactly do they do this? Well, an SSD on the outside
looks almost no different than a traditional hard drive. This
design is to allow the SSD drive to put in a notebook or desktop
computer in place of a hard drive. To do this, it needs to have
the standard dimension as a 1.8, 2.5 or 3.5-inch hard drive. It
also uses the common SATA interface so that it can easily be
placed into any PC as a hard drive would.
Why Use a Solid State Drive?
Solid state drives have several advantages over the magnetic
hard drives. The majority of this comes from the fact that the
drive does not have any moving parts. While a traditional drive
has drive motors to spin up the magnetic platters and the drive
heads, all the storage on a solid state drive is handled by
flash memory chips. This provides three distinct advantages:
Less Power Usage
Faster Data Access
Higher Reliability
The power usage is a key role for the use of solid state drives
in portable computers. Because there is no power draw for the
motors, the drive uses far less energy than the regular hard
drive. Now, the industry has taken steps to address this with
drives spinning down and the development of hybrid hard drives,
but both of these still use more power. The solid state drive
will consistently draw less power then the traditional and
hybrid hard drive.
Faster data access will make a number of people happy. Since the
drive does not have to spin up the drive platter or move drive
heads, the data can be read from the drive near instantly.
Hybrid hard drives do tend to mitigate the speed aspect when it
comes to frequently used drives. Similarly, Intel's new Smart
Response Technology is a similar method of caching on a small
solid state drive to produce similar results.
Reliability is also a key factor for portable drives. Hard drive
platters are very fragile and sensitive materials. Even small
jarring movements from an impact can cause the drive to be
completely unreadable. Since the SSD stores all its data in
memory chips, there are fewer moving parts to be damaged in any
sort of impact. While mechanically SSD drives are better, they
do have a limited life span. This comes from a fixed number of
write cycles that can be done on a drive before the cells become
unusable. For most consumers however, the write cycle limits
tend to still allow the drives to last roughly five years or
more which is longer than the average computer system.
Why Aren't SSDs Used For All PCs?
As with most computer technologies, the primary limiting factor
of using the solid state drives in notebook and desktop
computers is cost. These drives have actually been available for
some time now and have come down dramatically. Drives are
finally reaching the $1 per gigabyte price mark that makes them
more feasible for consumer use. Mind you, this is still ten
times the cost of a similar hard drive technology so it still
has a high cost.
Capacity is also a major factor in the adoption of solid state
drives. The average notebook computer equipped with a SSD will
have around 128 to 256GB of storage. This is roughly equivalent
to what laptops of several years ago came equipped with. Today,
most laptops feature 500GB or more of storage with a hard drive.
Desktop systems have an even greater disparity between SSD and
hard drives as the average desktop comes with 1TB or more of
storage.
Even with the huge difference in capacity, many people are
finding that most computers have far more storage capacity than
they typically have. Only a large collection of raw digital
photo files and high definition video files will likely fill up
hard drives quickly. As a result, solid state drives will
generally offer a sufficient level of storage for most laptop
computers. Additionally, high performance external options
thanks to USB 3.0, eSATA and even Thunderbolt make adding extra
storage space with an external hard drive quick and easy for
non-essential files.
