Why are SSDs more efficient and powerful than HDDs?

Nowadays, SSDs are new definition of storage. Well yeah, since the inception of personal computer era, storage components have improved a lot and that brings us to the day we see the most efficient storage and transfer with help of SSD.

Yeah, many might say that HDDs are not useless and has its value, and, we’ll also agree with them all based on the fact that HDDs are cheaper yet mostly used storage equipment throughout the globe.

As said, SSD is a new technology brought by the reputed brands in gadgets industry and hence you’ll notice its presence in almost all newly launched models of laptops.

So in this article, we’ll discuss about the basic difference between SSD & HDD along with the facts you should know about SSDs. Yeah, our aim is to discover the reasons behind SSD’s superior performance and utmost efficiency in this article.


The SSD is a new tech gadget that’s designed to provide higher transfer rate and better storage. And, this device is around since couple of years only.

Moreover, this device does nothing new than an HDD yet people prefers this one over an HDD. Well, there are reasons as mentioned earlier. But, basic fact remains the same that an SSD is designed for storage and efficient transfer.

Furthermore, one could say that SSD’s transfer rate is 10X higher than an HDD because both works on different storage mechanism.

Yeah, an SSD works on NAND mechanism where data gets stored on a particular location of memory designed on this drive. And, it accesses these data using current and unlike an HDD it don’t need a rotator or spindle to loop through the data stored on it.

Yeah, a laptop with an SSD is much better and efficient compared to the laptop with a hard disk drive.


An HDD works on a magnetic storage mechanism where data gets stored on a drive and to retrieve it, it rotates on its own. Basically, it can’t work without a power supply while an SSD is capable of operating even without an active power connection.

Yeah, it has couple of underlying components that helps it in storing & retrieving process of the data. Well, primarily it uses a mechanical platter, a spinning disk, a rotator, a read/write head for the functions to carry out.

Well, similarly to the SSDs, an HDD too can help in booting up the device as it can store and access the operating system.


Well, we all knows that SSDs are newest technologies and it’s more efficient and faster compared to traditional HDDs. But, to understand the WHY behind the reality of its better efficiency, we’d like to explain couple of things in a bit of detail

1. Scientific Built of HDDs & SSDs:

Yeah, old day’s HDD uses SATA technology which is slower and older compared to the PCIe express which has been used by most of the SSDs on the market. Yeah, that’s new and it helps an SSD to provide better efficiency and faster transfer rate compared to an HDD.

Moreover, SSDs works based on an electrical mechanism which is not dependent on any other component while HDDs are dependent on rotators & read/write heads and hence it makes a big difference in obtaining better transfer rates.

2. SSDs Consume Less Power than Traditional HDDs:

As mentioned earlier, an SSD works on an electrical fundamental while an HDD works on a magnetic mechanism. And, this makes a difference in power consumption as well.

Yeah, an SSD will drain less power compared to an HDD and hence it’ll prevent inlying issues like overheating etc.

Yeah, that’s the reason playing a role in obtaining more stars as a new era of storage & transfer technology as well.

Well, less power consumption means more battery life and longer usage frequency.

3. SSDs are Noiseless:

Yeah, as SSD don’t seek help from any subsidiary components and works on its own, it creates near to none noise. While, an HDD works with help of a rotator and hence when you transfer large set of data, you’ll notice noise coming out of it.

Also, it causes wear & tear issues that leads to malfunctioning of the device at all. And, that’s the reason we’d say that SSD is more efficient and powerful compared an HDD.

4. SSDs don’t overheat:

Due less influence of relying components on SSD, it don’t catch heat too quickly. And, that’s another reason, one could say it’s better compared to an HDD.

Yeah, an HDD will catch heat too quickly and you’ll have to put your laptop on rest for couple of hours in extreme cases.

5. SSDs are Immune to Magnetization and Fragmentation:

Well, as an HDD works on fragmentation method of storage, it starts getting overload with the incoming data and slowly degrades the performance over the time. However, an SSD is capable of storing your data at any place and accessing it automatically, it don’t need a physical read or write head and hence one could say that it’s immune to the issue of fragmentation.


Well, both storage devices has its own plus and minuses. However, based on numerous studies carried out by the big brands of the industry it’s no more a secret that an SSD is capable of handling storage requirements more efficiently compared to an HDD.

However, with this fact, one can’t say that HDDs will take an exit from the market within couple of years because it’s still a go to choice of many tech geeks. Yeah, reason is budget as HDDs are cheaper compared to an SSD.

Still, when it comes to our opinion, we’d say that none can beat the capabilities and functionalities offered by an SSD when it comes to the efficiency and performance.
