In 2020 almost all computers has a SSD inside, but why?

There are a lot of reasons you should change your HDD with an SSD.

Especially if you are using Windows 10 or programs like Adobe Photoshop.

In this article, I’m going to break down why should you switch to an SSD, and what are the benefits to have one.

According to Wikipedia, a solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage.

It is also sometimes called a solid-state device or a solid-state disk.


Benefits of using an SSD over HDD

There are a lot of benefits using an SSD.

Here is a table with the advantages of SSD over HDD.

What's the Difference Between an HDD and an SSD?

The traditional spinning hard drive is the basic non-volatile storage on a computer.

That is, information on it doesn’t “go away” when you turn off the system, unlike data stored in RAM.

A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the original Star Wars trilogy, or your digital music collection.

A read/write head on an arm accesses the data while the platters are spinning.

An SSD does functionally everything a hard drive does, but data is instead stored on interconnected flash-memory chips that retain the data even when there’s no power present.

These flash chips are of a different type than the kind used in USB thumb drives, and are typically faster and more reliable.

SSDs are consequently more expensive than USB thumb drives of the same capacities.

Like thumb drives, though, they’re often much smaller than HDDs and therefore offer manufacturers more flexibility in designing a PC.

While they can take the place of traditional 2.5-inch or 3.5-inch hard drive bays, they can also be installed in a PCI Express expansion slot or even be mounted directly on the motherboard, a configuration that’s now common in high-end laptops and all-in-ones.


This is where SSDs shine. An SSD-equipped PC will boot in less than a minute, and often in just seconds.

A hard drive requires time to speed up to operating specs, and it will continue to be slower than an SSD during normal use.

A PC or Mac with an SSD boots faster, launches and runs apps faster, and transfers files faster.

Whether you’re using your computer for fun, school, or business, the extra speed may be the difference between finishing on time and failing.


Because of their rotary recording surfaces, hard drives work best with larger files that are laid down in contiguous blocks.

That way, the drive head can start and end its read in one continuous motion.

When hard drives start to fill up, bits of large files end up scattered around the disk platter, causing the drive to suffer from what’s called fragmentation.

While read/write algorithms have improved to the point that the effect is minimized, hard drives can still become fragmented to the point of affecting performance.

SSDs can’t, however, because the lack of a physical read head means data can be stored anywhere without penalty. Thus, SSDs are inherently faster.


An SSD has no moving parts, so it is more likely to keep your data safe in the event you drop your laptop bag or your system gets shaken while it’s operating.

Most hard drives park their read/write heads when the system is off, but they are flying over the drive platter at a distance of a few nanometers when they are in operation.

Besides, even parking brakes have limits.

If you’re rough on your equipment, an SSD is recommended.


Hard drives are more plentiful in budget and older systems, but SSDs are becoming the rule in high-end laptops like the Apple MacBook Pro, which does not offer a hard drive even as a configurable option.

Desktops and cheaper laptops, on the other hand, will continue to offer HDDs, at least for the next few years.

Form Factors

Because hard drives rely on spinning platters, there is a limit to how small they can be manufactured.

There was an initiative to make smaller 1.8-inch spinning hard drives, but that stalled at about 320GB, and smartphone manufacturers have settled on flash memory for their primary storage.

SSDs have no such limitation, so they can continue to shrink as time goes on. SSDs are available in 2.5-inch laptop-drive-size boxes, but that’s only for convenience in fitting within established drive bays.


Even the quietest hard drive will emit a bit of noise when it is in use.

The drive platters spin and the read arm ticks back and forth.

Faster hard drives will tend to make more noise than those that are slower.

SSDs make no noise at all; they’re non-mechanical.


An SSD doesn’t have to expend electricity spinning up a platter from a standstill.

Consequently, none of the energy consumed by the SSD is wasted as friction or noise, rendering them more efficient.

On a desktop or in a server, that will lead to a lower energy bill.

On a laptop or tablet, you’ll be able to eke out more minutes (or hours) of battery life.


While it is true that SSDs wear out over time (each cell in a flash-memory bank can be written to and erased a limited number of times), thanks to TRIM command technology that dynamically optimizes these read/write cycles, you’re more likely to discard the system for obsolescence (after six years or so) before you start running into read/write errors with an SSD.

If you’re really worried, several tools can let you know if you’re approaching the drive’s rated end of life.

Eventually, hard drives will wear out from constant use, as well, since they use physical recording methods.

Longevity is a wash when it’s separated from travel and ruggedness concerns.


Hard drives win on price and capacity. SSDs work best if speed, ruggedness, form factor, noise, or fragmentation (technically, a subset of speed) are important factors to you.

If it weren’t for the price and capacity issues, SSDs would be the hands-down winner.
