Top 7 Best 120GB And 240GB SSD In 2021- Latest Update

The Solid State Drive (SSD) used to be quite expensive earlier. That is why most people did not even think to afford them. But, with the gradual changes in technology, SSDs are now pretty standard in laptops to ensure an upgrade and a high-speed performance.

It boots up the computer in 15 seconds and improves the file opening speed by 30%. The SSDs introduce a new pace for transferring files, finding files, and data access time. The application start-up time is much shorter in SSD, so it is becoming a new favorite for all the laptop users out there. 

Which One Is Better?- SSD Or HDD?

SSD is comparatively lightweight than HDD. It includes a spacer tray to fill up the gap of the HDD because the HDD takes up more space. In addition, the power usage ratio is more than 6W in HDD, whereas, in SSD, it is less than 2W. 

HDD consumes a lot of storage space, so it creates pressure on the battery. But, SSD is so lightweight that it ensures an even longer life of the battery. HDD makes a sound while the machine is on, but SSD is silent. It has flash memory chips that dissipate the heat, and thus SSD does not overheat the laptop when it is working. 

However, HDD has a moving disk platter, which makes it less durable. But, SSD does not have any moving parts, and the flash memory is soldered into the circuit board, making the device shockproof. Even the application startup time is longer in HDD, while it is much shorter in the SSD.
