Advantages of SSD over HDD

Solid hard drive or SSD is a storage system that stores our data on chips. Solid disks, unlike traditional hard disks, have no mechanical parts.

Currently, hard drives have reached an interesting storage capacity, reaching in some models up to 4TB, existing units of up to 16TB in an industrial version.

A traditional hard drive, HHD has until recently been the storage system on any computer. It is made up of a metal layer with magnetic cover, a mechanical arm, and a read and writes head that stores the data.

An SSD stores data on a series of interconnected flash memory chips capable of retaining information even when there is no electrical connection. The chips can be permanently embedded in the motherboard or can be embedded in a device that can be connected to the motherboard of any computer. This type of chip is different from the one used by USB memory, being much faster and more reliable, hence the same capacity as the SSD is more expensive than a USB memory.

SSD hard drives began operating in the late 2000s, with the rise of netbooks, ultrabooks, and other types of laptops. The size of the SSD disk has been standardized in the 2.5 ”format, making it possible to remove an HHD from any laptop and replace it with an SSD.

What advantages does buying an SSD offer?

Price remains the key factor when choosing a hard drive, but really, why buy an SSD?

Speed: A computer equipped with an SSD hard drive boots up in a few seconds while a computer equipped with an HDD takes about a minute to be operational.

The SSD starts, launches and runs all the programs and performs the file transfer in a much faster way.


SSD hard drives lack moving parts, making it much more difficult for them to be damaged by a blow or sudden movement. Traditional hard drives run on the physical drive a nanometer distance when they are working. If you ask the computer a lot, it is highly recommended to use an SSD hard drive.


An HDD hard drive works by a turntable and there is a limit to its size. An SSD hard drive has no limitations, so although its standard is at 2.5 ”, as time passes they will decrease in size to accommodate new laptops and tablets.


Any hard drive with a mechanical arm will make some noise when it is working and will make more noise the faster it is. On the contrary, an SSD hard drive does not produce any noise since it does not have mechanical parts in operation.

And remember, a computer with a solid hard drive is going to be much faster in starting and launching programs, being an ideal element for professionals looking for speed such as engineers, graphic designers or audio technicians or musicians, or simply for those who are accustomed to going with their computer anywhere and want it to start and shut down immediately.
