What is SSD Full infromation of SSD?

Friends, as we all know, our computer has data storage capacity and this memory is of two types, one of which is the primary memory and the other is secondary memory. Basic memory (RAM) is the primary memory of a computer where data is stored immediately during computer operation while a second memory (HDD, SSD) is the memory where any data, system, software etc. is stored. is stored permanently i.e. for a while. It saves.

 

However, the most commonly used second memory in our computer so far is Hard Disk Drive (HDD) but it is an old technology based on Data Storage Solution where Data Read / Write Speed ​​slows down because it has a Mechanical concept used . data storage.

Therefore, in addition to this, a state-of-the-art data storage device has been created, namely SSD which is a fast data storage solution. But do you know what an SSD is? How does the SSD work? What are the types of SSDs? Why did we need an SSD? What is the difference between an SSD and an HDD? If you have come here to find out about the same questions, then you are in the right place because today we are going to discuss SSD i.e. Solid State Drive in this article, so please read the whole article carefully

What is an SSD?

SSD, whose full name is Solid State Drive, is a Flash Chip-based data storage device, where it does not have a component like Hard Disk Drive for computer data storage, but has as much Flash as RAM or Pen Drive. Chip is installed where data, software etc. computer is stored permanently.

SSD read / write speeds are much faster than a hard disk, so for newer computers or laptops today, the SSD is widely used instead of a hard disk. Although an SSD is more expensive than a hard disk, its use increases exponentially to increase computer speed and maintain computer performance.

 

How is data stored on SSD?

As we all know that a computer is an electronic and electronic machine, in that case, any data that is on a computer or given to a computer, whether written, graphical or computer audio, are all 0. and 1 Because a computer is an electronic device and any electronic device can only understand Computer Language which is a low level programming language such as ABCD or Audio, not Video.

No matter what kind of data or instructions we place inside the computer, it has been presented and processed in 0s and 1s inside the computer, but we get the output in our own language and this function is done by the computer. The software (operating system) available is available. Software to define every type of input provided by a computer whether it is text type, in the form of a video audio video or any other type of sound, command, etc., by converting it into binary digits inside. It works and then when the same data is processed inside the computer and presented to us in the form of extraction, then with the help of software, it is converted into binary into a language we understand (Text, Audio, Video, graph etc.) presented as.

Binary Digit in the range of 0 and 1, in this case 0 means Turn Off which is Low Signal and 1 means Turn on which is Open Signal. It is called Bit in the world of computer memory which is a small part of computer memory, with 0 = 1Bit and 1 = 1Bit. On the basis of this, the size of the computer data and the final volume of the storage device are known.

In this way, any data in the entire region within the computer goes and stores in the form of 0.1 (eg 00011101110), which is an electrical signal made with a high-low-high pattern.

When it comes to storing data on an SSD, the same happens with an SSD, there is a PCB inside the SSD i.e. Solid State Drive which is packed with many NAND Flash Chips. Whenever we store any data permanently while operating a computer, that data will be an internal binary digit signal generated by the High-Low-Low pattern in the form of the NAND Flash Chip available on the SSD. is stored in.

Why was an SSD needed?

We all know that computer development did not happen today but many decades ago and the most advanced computers we see today were not so developed before, and there was no need for advanced computers then, but as demand increased. and technology has improved, as has our computer and the capacity of all its components increased.

By the way, in general, 2 decades ago, our computer had reached a good level and was capable of multitasking, as well as HDD-Hard Disk Drive was used as Secondary Storage, but after that as much as There was rapid development in the computer's Processor, RAM, Motherboard, etc. Hard Disk Drive could not develop as fast, although it also developed but comparatively and if we look at the speed of all the parts like Processor, RAM etc., all the time. Its neglect used to slow down the Secondary Storage Device, due to which the speed of the whole computer was slowing down due to only one part, even today if a computer has an i9 processor and HDD is installed for secondary storage, then that Even in the computer, we do not get the same speed as can be found in the computer with SSD.

In fact, the working concept of HDD is such that the same speed cannot be obtained from it as can be found in any flash chip based storage.

In view of these problems and needs, such a storage solution based on Flash Chip was developed whose speed is many times higher than HDD, which is named SSD. With its arrival, the bottleneck of the computer worked and the speed was boost-up.

What is the difference between SSD and HDD?

• Talking about the difference between SSD and HDD, the main difference between these two is that.
• SSD has high speed whereas HDD is very slow.
• SSD consumes less power whereas HDD consumes more power in comparison.
• There is no noise of any kind during working from SSD, whereas from HDD there is sound of                Spinning of Platter.   
• The data in SSD is stored inside the flash chip whereas the data in HDD is stored on top of the              magnetic disk called platter.            
• SSD is expensive whereas HDD is very cheap.

Based on Memory Chip:-

When it comes to the classification of SSD on the basis of memory chip, then on the basis of this it is seen that on the basis of how many bits of data is given in a cell of the memory chip used in SSD, it can be seen. What can be the life-cycle of SSD, what can be its speed, what can be its storage capacity, etc.

There are four types of SSD on the basis of memory chip:-

• SLC (Single-Level Cell): Single-Level Cell means that 1Bit of data can be stored in one memory cell of the memory. It is an advanced type of SSD which is the most expensive but has the highest speed and also has a longer life. SLC type SSDs are generally used for enterprise grade solutions.

• MLC (Multi-Level Cell): Multi-Level Cell means that it can store more than one bit of data in one of its memory cells but here Multi-Level Cell means 2Bit i.e. one memory cell of MLC type SSD. It has 2Bit data store, which reduces the cost of MLC type SSD due to higher data density, due to which it is cheaper than SLC type SSD. However, both its speed and life are less than that of SLC.

• TLC (Triple-Level Cell): TLC which means Triple-Level Cell i.e. 3Bit of data can be stored in one of its memory cells, due to which its storage capacity becomes more than SLC, MLC but its speed and life is less. it occurs. TLC Type SSD is a widely used consumer grade SSD, which is also low in price.

• QLC (Quad-Level Cell): QLC which means Quad-Level Cell i.e. can store 4Bit of data in one of its cells. It has the highest data storage capacity, but both speed and life are less than others, due to which Quad-Level Cell Based SSDs are cheap.

On the basis of Interface :-

When it comes to the classification of SSD on the basis of interface, it is seen on the basis of which interface protocol supports SSD and on the basis of this it is decided that the maximum speed of the SSD being installed in that system. What will be the Banditwidth.

There are mainly two types of interface used for SSD:-

• SATA: SATA, which stands for Serial Advance Technology Attachment, is a computer bus interface that connects host bus adapters to large storage devices such as hard disk drives, optical drives, and solid-state drives. What was its development in the year 2000 AD, which is an improved form of the old PATA interface. This is the main interface protocol for HDD Attachment, in which SATA Interface Protocol Based SSD can also be installed very easily.

• NVMe: NVMe, meaning Non-Volatile Memory express, is a virtual host and backup protocol used to transfer data between business and client programs and hard disk drives with a high-speed computer bus Peripheral Component Interconnect. Designed to accelerate. Built in 2011 AD. The SSD speed used by the NVMe Interface Protocol is higher than the SSD with SATA Interface Protocol.

On the basis of Form Factor: -

In the case of solid state drives, the form factor refers to the area in which it refers to its size, the type of network connection, and the physical location occupied by the computer.

On the basis of form factor, there are mainly three types: -

• 2.5 ": The standard 2.5-inch SSD form, which fits inside most of your laptop or desktop drives. As more users convert their hard drives to hard drive, the 2.5-inch drive is all HDD. is a standard SSD 2.5-inch Drive is designed by developers without the need to change the interface of the interface connector, and the SSD is about the same size as a 2.5-inch HD HDD.

• M.2: The smallest form factor for SSDs is called M.2, which is similar to a small PCB rod. M.2 SSDs are connected to motherboards via an M.2 socket, designed for systems such as notebooks, tablets, and ultrabook.

• mSATA: The smallest SSD form is called mSATA. The mSATA SSD is an eight-part 2.5-inch drive and is designed to connect to an mSATA socket on the motherboard of the system. MSATA drives are used on very small devices or as second-hand drives.

SSD features?

• It talks about the features of the SSD, its main feature being that its read / write speed is very high.
• Low weight, therefore it is the best way to a portable device.
• The SSD consumes less power than the hard disk drive, making textbooks an energy-saving option for laptops such as ultrabooks.
• Even when an SSD gets old, there is little difference in its speed.
• It does not create noise during operation.
• Like a hard disk, there is no chance of bad sector production.
• Overall his health is also good.

Disadvantages of SSD?

• Its biggest disadvantage is that it is more expensive compared to a hard disk, so using it as a great storage solution proves it is expensive.
• Other than that, SSDs usually have no significant damage.
