What is SSD Hard Drive
Who
is not listen about SSD Hard Drive. Today we tell you What is SSD Drive and what is basic diffrence between SSD VS HDD , how it
works. NAND's most used SSD-drives, or, as it is called, flash memory. Such
chips are used in conventional flush, only solid state storage, they are
reliable and high speed due to the presence of the controller of information
processing. Due to the low cost they are widely used in SSD, so that these
devices are quite affordable for most users. Another advantage of this type of
recall is that it is non-exhaustive and does not require additional power
supply operation.
In
addition to NAND technology, solid state storage is sometimes used RAM-SSD.
This type of memory has a great record and data reading speed by using the
chips used in creating memory. SSD-drives that use RAM, will often require a
permanent connection to the power, if additional batteries are installed in the
event of a sudden power failure. Due to the high production cost of these
drives, they are rarely found in home computers and laptops. Mainly used in
computer systems of large companies to increase the speed of working with
RAM-SSD databases.
Difference Between HHD & SSD
Nand
memory used in most stores today. Despite these SSD-drives differ from each
other in data writing speed, read data and cost. It all depends on the chip
used in the drive: SLC, TLC or SSD MLC. What is it and what is the difference?
So different notify flash memory types. The most common technology is MLC,
under one cell, under which two bits of information can be stored. TLC makes it
possible to record as many as 3 bits, but this leads to a more rapid reduction
of cells, so the technology is not very popular. The fastest and most durable
is the SLC-memory, which can be used to record only a bit of data in each cell.
In addition to only large investment losses, can be identified SSD is 2 times
higher than the cost of MLC.
Controller
The
controller is the most important element without which it cannot function SSD
drive. Turned on what it is and what its character is. These devices are
responsible for balancing workloads between storage units, performing read and
write data, error correction, and file compression. The controller matches a
command center where decisions related to data processing. This part depends on
the speed of the SSD and its longevity. The main component of the controller is
a dedicated microprocessor, which carries the entire load. In addition, the
performance of the device depends on the quality of the firmware.
Many
companies, engaged in the production of SSD-drives because their manufacturing
technology is very simple and requires less time than the creation of classic
hard drives. All you need - is to buy memory chips, controllers and boards,
where all will come unsoldered. Afterwards it is placed in a beautiful body
with construction logo - and the product is ready for sale. But many components
for solid state drives have a high cost for the correspondingly high costs that
would require the creation of a quality controller and firmware for it. Because
of this, the cost of SSD-drives today is much higher than that of ordinary hard
disks.
Now
consider a hybrid SSD HDD. What kind of device and what is the intention? Every
year, SSDs are gaining more and more popularity. Technology still does not
tolerate, and standard hard drives are gradually replacing more complex
systems. SDD-drives are present in many computers, but the main repository of
information, and not in addition. And all because their cost is much higher
than traditional hard disk drives. To compensate for the difference between the
two types of drives, it was built a hybrid hard disk SSD. Let's take a closer
look at what kind of device and what the benefits are.
At
the heart of the hybrid drive is still the same Spiderman without any change.
But in the case of this campaign, installed more chips with flash memory, which
is used as a buffer zone. It is copied information that is most commonly used.
When compared to traditional hard drives, it is possible to increase the
download speed of some applications and the operating system. Maximum size of
hybrid SSD like flash memory - 8GB. Given this result? In fact, we have
something between a hard drive and a small solid state drive. Buffer memory cannot
download data or install applications. This priority is used as a reserve for
launching programs the user cannot control himself. As the price, SSD standard
below the cost hybrid hard, but more HDD, in addition, they are not very
popular in our country, why are not sold anywhere.
How SSD Works?
An
integral part of modern computers is the SSD drive. What this device is and how
it works, we found bitumen highlighting the main advantages and disadvantages
compared to traditional hard disk. Let's start with the positive aspects of
solid state drives.
The most
important advantage of SSD is incredible reading speed and writing information.
They have many times the performance of hard drives. For example, some data
processing speed drives more than 500 MB / s. In practice, this rapid work
programs.
