what is ssd in laptops

Are you curious about what is SSD in Laptops? You might have heard the word SSD a lot more if you are related to computers to gaming. Don’t worry, today I am going to guide you completely about the SSD that what it is and how it works.

What is SSD in Laptops?

An SSD or a Solid-State Drive is an innovation in storage devices which use a simple chip called NAND Flash Memory Chip and gather the data via Flash-Based Memory and work very fast than HDD Drives.

In the modern world, SSDs have replaced the old mechanical and HDD hard drives. It uses flash-based memory which is much faster than the other drives. The old drives worked slowly which would often make the PC slower even if the PC had a good Ram and processor. SSD has a low read-access time which significantly speeds up our system.

How Does an SSD in Laptops Works?

The new SSD works in a completely different way. As we mentioned above, the SSD used a very simple chip which is known as the NAND Flash memory chip. This chip has no moving parts and gathers the data via flash-based memory.

Not at all like a hard drive (HDD), as SSD has no moving part to split or to go back and forth. An HDD comprises a circular spinning disk with a read/write head on an actuator. The HDD system and hard disk are joined as a coordinated unit. Companies and PC makers have used spinning plates in previous decades due to its low cost. But today most of the new upcoming Desktops and Laptops come in SSDs.


In beginning, data was stored first on some mechanical hard drives known as HDD. These traditional HDD hard drives are mostly based on moving disk inside, like a read/write head that goes to and fro to gather the whole data. This makes the data gathering slower and thus makes the computer slower.

The first experiments were started on SSD in the late 1950s. In 1970-80 they were brought in use in the high-end supercomputers. Yet this technology was very expensive for a normal user and also it didn’t have high storage capacity. Its capacity was about 2MBs-20MBs. 

Therefore they were only used in supercomputers in special sectors such as military and aerospace departments. After the 1990s these SSD chips were made in the use of consumers and now in 2020 almost every new laptop arrives with built-in SSD Chips.

At the beginning of the 1990s, the advancement in the hardware field caused the SSD prices to drop. After that SSD started to become a more faster and reliable drive to provide faster speed and access.

EMC also is now known as Dell EMC has been given the credit of being the first vendor to bring SSD in the market as enterprise storage hard drive in 2008.

The memory chips on SSD work comparatively to the RAM chips. Instead of saving data on a magnetic disk, these files are saved on NAND FLASH cells. Each cell of NAND flash can store up to 256 KBs -4MBs. 

The SSD has the exact address of the grid/cell and thus when the PC requests for the data, the file is instantly available for processing, unlike HDD where one has to wait for read/write head to access the data. Thus the access time for SSD is measured in a nanosecond.

What are solid-state drives used for?

SSD selection started in superior innovation zones and in advanced PCs, where the SSD’s incredibly low access times and high output made it clear that it’s worth the greater expense. However, they have since become an acknowledged alternative – or even the default decision – in low-cost standard Laptops and PCs too.

Working Of SSD’s in Detail

A spinning HDD disk reads and composes information magnetically, which is the most-oldest storage media inconsistent use. The magnetic properties, nonetheless, can prompt mechanical breakdowns but an SSD, alternately, peruses, and composes the information to a cell of interconnected flash memory chips, which are manufactured out of silicon. 

Makers fabricate SSDs by stacking the chips in a grid shape to get fluctuating densities. To prevent unpredictability, SSD makers structure the gadgets with floating gate transistors (FGRs) (FGRs) to hold the electric charge. This permits an SSD to store information even if it’s not connected to a power supply. Each FGR contains 1 Bit of information, assigned either as a 1 for a charged cell or a 0 if the cell has no electrical charge.

Advantages of Having an SSD

Business Work

Those offices of organizations where the workload is enormous for example big industries, trade centers, etc. depend on SSDs to a huge extent. They require much work in less time thus only SSD can provide them with such an opportunity to access and save information in less time and respond to many customers at a time.

Gaming Performance

Nowadays gaming has become much important for the young generation. Some time ago people needed large CPUs to have better system requirement accessories. In modern-day people look for a PC which is small in size. The new upcoming laptops are way much thinner than the older ones. Apart from being thinner, they are also much more effective. It’s because of SSD. SSD chips allow us to have a better experience and use less space and thus can be placed in thin laptops.

Also, SSD enhances the gaming experience as it speeds up the PC and also enhances graphics. The gaming experience is enhanced because gaming requires many files such as maps, missions, surfaces, characters. Thus in SSD, the file location is exactly available and so the system doesn’t have to look for the data which greatly increases the fun in playing PC Games.

Portability Issues

As SSD chips are much smaller as compared to the older mechanical hard disks they require less storage space making the laptop thin in size, thus it easier to take a small-sized laptop. Also, SSD requires less charge to operate and thus increase the battery life to a noticeable extent. Now high featured devices to in smaller size and are easy to be taken anywhere. That’s why we can say that SSDs have solved portability issues.

Workers Convenience

Workers in a company where either customer visits or if there is more work need SSDs to get access to the data in less time to serve the customer quickly and finish his/her work in a given time. Thus the worker also gets time to relieve himself and takes some rest.


Big servers like those which run websites need SSDs to work fast to provide the user with better user experience.

Types of SSD

After knowing about what is SSD in Laptops, you might be thinking to buy one. When you buy an SSD you will experience that the SSD also comes in multiple variants. Important of them are mSATA and PCle. If you don’t understand these terms, then don’t worry read below we have explained them well so that you can get a clear idea of it.

PCIe and NVMe SSDs:

PCI Express (PCIe) is regularly used to interface illustrations cards, arrange cards, or other elite peripherals. This interface gives you high data transmission and low latency, making it ideal when you need blasting quick communication between the SSD and your CPU/RAM. 

SSDs that use this communication type depends on the “Non-Volatile Memory Express” (NVMe), which offers higher input and output and even lower inactivity than SATA (which we’ll get to in a second). NVMe gloats up to 16 Giga Bits for each second of crude throughput which, on account of different equal channels, runs at up to 4,000 MB for every second.

mSATA III, SATA III, and conventional SSDs:

“Sequential Advanced Technology Attachment (SATA)” is a more established interface that was planned explicitly for capacity, with speed up to 6 GigaBit per second or around 600 MB for each second. SATA is gradually being replaced by NVME, which is basically faster in it. In any case, more seasoned computers or ones with a hard drive would in any case profit by a move up to a SATA-based SSD.

Image 1SSDs are accessible in a wide range of capacity limits, beginning at around 32 GB and extending up to 5 TB in the purchaser space. Obviously, the limit is essentially higher for big business-grade storage, with proportionately more significant expenses.

During the small period of netbooks (recall those? They were modest, yet moderate and wobbly), the renowned Asus Eee PC arrangement used 1-4 GB of SSDs as capacity, from which parts of the working framework were run for quicker access. This was the principal standard utilization of SSDs. 

From that point on, ultrabooks and in the long run work area PCs began to receive SSDs. Common storage today ranges between 250 GB to 500 GB, which is enough to hold your Windows working framework, the most widely recognized projects, and a ton of your own documents.

How to Get the Best Performance From Your SSD

You can spend up to a limit on your laptop but no matter how much you spend your system the slowest part of your computer is the hard disk. Even SATA SSD which comes with 600 MB is slow when it is compared to other components even though it is capable of processing and transferring about 20 -30 GBs of data per second.

We would suggest NVMe SSD which is the best choice and the investment is worth a new computer upgrade.

We can demonstrate the difference between HDD and SATA SSD by an experiment. We took a measurement of six years old gaming PC having HDD and then replaced the HHD with a SATA SSD and then again we took some measurements of some tests.

The results of those experiments as given as under

Boot time

HDD: 79 seconds

SATA SSD: 17 seconds

Game loading-time (GTA V)

HHD: 133 seconds

SATA SSD: 25 seconds

This is an amazing innovation in the user experience of computers. As you can see the difference with the measurements of HHD and SSD, it means too much for a user. This makes SSD worth a bug investment

That’s not all, even SSD needs maintenance. You can even get better performance for years if you keep it maintained. But our advice is that you should use a professional method to keep it maintained and don’t use old traditional defragmentation tools on these as the old HDD. These tools are not required for it and it may harm it and damage its performance.


It is considered that the performance of SSD flash chips is faster than the mechanical HDD hard drive in almost every field. Required time and latency are reduced and performance is substantially increased. Moreover, users enjoy a much faster PC and its boot time.

An SSD incorporates wear leveling to expand drive life expectancy. Wear leveling is ordinarily overseen by the flash regulator, which utilizes a certain algorithm to manage message so write/delete cycles are conveyed uniformly among all the cells in the gadget. Another procedure is SSD overprovisioning to limit the effect of trash assortment compose intensification. This restricts the usable stockpiling on the SSD to a specific rate.

SSD lifespan vs. HDD

Various variables affect the life expectancy of SSDs and HDDs, including dampness and the impact of metals oxidizing inside in the drives. Information on the two sorts of media will degrade after some time, with HDDs for the most supporting a higher number of drive writes every day.

As we know that the moving parts in HHD have more chances of getting being damaged. Therefore to get over on this issue, manufacturers add sensors called “shock sensors” to keep hard drives and other essential components safe. These sensors use a piezo resistive effect to detect if the machine is in danger and then the sensor will take automatic steps to power off the HDD or any hardware.

Heat is also an important factor that affects the life of a drive. It is recommended that hard drives should be stored in cool places to increase their life. There is more chance of heating up of a mechanical drive as compared to SSD. Though if an SSD constantly operates at high temperature for a long time, then there is a fear of leaking of electrons from NAND FLASH memory cells.


SSD is said to be more durable and every SSD comes with a warranty for some years. Every SSD doesn’t have the same age. An SSD used only for simple works, generally work more than the one which is used more. Yet the life of SSD is regarded as more than that of HDD.

Interface Considerations

SSD uses an electrical signal to connect and communicate with the processor. The interface of the SSD makes sure the max work rate and throughput and min latency rate and to enhance working capabilities. SATA interface is generally known as the least expensive drive type. 

Therefore the manufacturers of these types of SSDs such as NVMe, SAS, and SATA all usually use the SATA interface. The manufacturers need to design such products to meet the demands of the customers such as more capacity, better performance, endurance, size, and better price.

The performance of an HDD can be damaged when data is divided into various segments on the disk drive. The best approach to fix the disk plate is with a method known as defragmentation. SSDs don’t store information attractively, so the read exhibition stays consistent, paying little mind to where the information is stored on the drive. Because of their lower latency rate, SSDs are streamlined to do inline data reduction with an insignificant effect on the performance of the system.

Monitoring and Management Tools

The SSDs especially NVME, SAS, and SATA use “Self-Monitoring, Analysis and Reporting Technology shortened as SMART to run tests to check whether all of its parts are working properly or not. SMART is programmed to give auto alerts and performance reports as well as to update the firmware on time.

Power usage

The drive interface additionally indicates the most extreme intensity of an SSD. As we know that numerous undertaking SSDs are built to be tuned while operating. This function permits clients to well enhance the gadget’s performance and speed.

Power Redundant

SSDs come with an internal small RAM cache as a firewall for conditional and other strategic endeavor data. Information is put away in RAM and therefore kept in touch with a recently erased cell of the clash on the SSD. This guarantees that no important data is lost. Also, endeavor SSDs incorporate many capacitors to run the SSD and guarantee composes from RAM are finished so as to increase the speed.

SSD pricing

The price of an SSD is much higher than the HDD hard drives due to its unique shape and performance. Yet with the passage of time advancement in manufacturing techniques and technology and an increase in the number of users, the price of SSD is constantly dropping in the market allowing the customers at a low level to get a chance to use SSD as a possible alternative to HDD. The price ranges from 50$ – 500$ depending on how much capacity of the storage you require.

Increasing Market Of SSD

Due to the effect of Moore’s Law the market price of SSDs as well as their demand and supply are affected. More advances are expected to design a thick 3D NAND SSD when compared with the 2D NAND measure. Producers have tried their best to expand the respect guarantee they fulfilled worldwide need, with mixed up outcomes in the coming years.

In 2015 and 2017, worldwide interest for these SSD flash chips overwhelmed its supply. Accordingly, SSD makers needed to scramble to fill their pipelines. Changing demands for these flash-chips have kept its price range variable; however, the cost for an SSD stays higher than that of an HDD.

A report in June of 2018 from Trend-Force said that the prices of SSDs started to fall because of the oversupply of these SSD Flash chips. The number of chips was higher than the demand thus it resulted in the price drop of the chips which made it possible for low-level people to accommodate themselves with such an innovation.

Likewise, SSDs have a set increased life expectancy with a number of write cycles before the execution of command gets inconsistent. This isn’t generally a burden essentially, as HDDs additionally corrupt and in the end, stop working after a certain time.


Here we conclude of article and hope that you know exactly What is SSD in Laptops and hope that now you know how amazing innovation this is in the field of computers and speed.
