In today’s generation, the computer is one of the most essential devices of all. More or less in every type of company, computers i.e.: Either desktop or laptop is one of the major devices which solves the issues, reduce the work time in a very efficient way. We all are familiar with computers. We use computers for regular work purposes such as official work, studio purposes, gaming, coding, and so on. Now there are a few key parts inside of it. They are logic board, processor, RAM, Storage device, optical driver, graphics card, power supply, chassis, and other peripherals. Let’s talk about how we can increase the data transmission speed.

Execution: For any kind of cod execution such as playing an audio or gaming or video editing all the core components work together such as processor, RAM, storage, and graphics unit. By working in a combined way we get a performance and get the work done. Most of us think the entire speed depends on the processor and RAM and graphics can boost the performance. But in reality, a lot of us forget about 1 storage device.

Traditional HDD: HDD stands for Hard Disk Drives. Every HDD has a re-writable disc inside of it, it can store any data and vice versa. Every storage device comes with a Read/Write speed, mainly it depends on the bus speed. In HDD there is another speed which is known as disc spinning speed i.e.: 5,400 RPM, 7,200 RPM, or 10,000 RPM. Now, RPM stands for Revolution per Minutes. If we see 7200 RPM is written on an HDD then we have to understand the best speed it can reach up to 7200 revolutions per minute which is quite good. But as these are electro-mechanical devices so due to the aging effect and day-to-day use we can observe the speed drop. After a few times, the transmission speed decreases drastically. Now even though you have a multi-core processor with a bigger RAM and graphical unit your whole system won’t be able to provide supreme performance. Because data is processed by the processor, RAM, and graphics but it must have to be read from and written to the storage device. Now, if your storage device can’t compete with all other high-performance components, then there’s no point in using these high-end cutting-edge components.

SSD: SSD storage is designed with NAND Flash Technology which can transfer the data way faster than the traditional bulky HDD. There are also different types of versions based on bus controller and form factors such as SATA 3, M.2, NvME, and a few others. In general, SSDs can read up to 10x faster and 20x faster than HDDs.

Key differences between SSD and HDD:

Key Parameters



Access Time

5.5~8.0 ms

0.1 ms

Random I/O Performance

Up to 400 IO/s

6000 IO/s


Failure Rate 2~5 %

Failure Rate 0.5%

Energy Savings

Consumes between 6 & 15 watts

Consumes between 2 & 5 Watts

CPU Power

Average I/O wait is 7%

Average wait time is 1%

Input / Output Request Time

Average time is 400~500 ms

Average Service time 20 ms

Backup Rates

20~24 hours

6 hours


So, it is always a better choice to get an SSD for your computer system if you’re obsessed with your current performance. Even if you’re using a laptop, can install an SSD also, but you should have the accessibility to install a new one or replace it with the existing one. In order to find it out, go see your laptop specification or you can search in the forums as well. Also, it’d work if you’re confident enough to open the laptop and check by yourself, but make sure to follow the steps, if not then go see a service point, you’ll get help for sure.
