SSD vs HDD, Which is Better

The existence of Solid State Drives (SSD) has actually been around for a long time, but few people know its essence. If you are buying a new laptop, it is most likely equipped with an SSD or both, an SSD, and a hard disk drive (HDD).

Most modern computers and laptops have switched to using technology SSD in recent years. Even gaming laptops that require more storage are equipped with high-capacity SSDs.

But, if you had to choose one, which would you choose, SSD or HDD? To better understand the options, see the explanation below.

What are SSDs?

SSD is a modern storage technology that does not rely on moving parts to store data. Instead, it is electronic and uses NAND (Negative-AND) flash memory.

This special flash memory chip determines the storage capacity and speed of the SSD. Also, SSDs are usually smaller in size than HDDs, which is why SSDs are available in modern PCs.

The main advantage that SSDs have over HDDs is that they have the ability to read and write data faster. SSDs come in a variety of shapes and sizes, available in a variety of connector formats.

What is HDD?

HDD consists of mechanical parts that move to store data. Traditional HDDs house circular disks called “platters” that hold your data.

The disk spins when the hard drive is active, making it possible to read and write data.

The disk speed determines how fast the HDD performs and how fast your operating system responds to it. Therefore, the read-write function of the hard disk is completely mechanical and depends on the state of the machine.

SSD vs HDD comparison

SSD vs HDD comparison
Offers read and write speeds of up to 2.2GB/s. The average maximum speed is around 200MB/s.
SSDs mostly have a storage capacity of up to 2TB. Comes with a variety of storage options with a storage capacity of up to 12TB.
It is more expensive than HDD in terms of storage capacity but offers much higher speed. It offers more storage capacity than SSD but has limited speed.

Storage capacity

You won’t find an SSD with more than 2TB of storage. In other words, most SSDs only have 1TB-2TB of storage.

Meanwhile, HDDs offer up to 12TB of storage capacity. Therefore, if you just want to store a lot of data, you should not choose SSD and choose HDD.


The main quality of SSDs that makes them superior to HDDs is their speed. SSDs are always faster than HDDs. However, the gap is more comprehensive with the latest SSD technology than ever.

Most HDDs are only available in two types of speed: 5400 RPM or 7200 RPM. These numbers show how fast the HDD disk spins according to disk performance.

A 5400 RPM HDD with a SATA III connector has a speed of around 100MB/s, while a 7200 RPM HDD has a speed of around 150 MB/s.

Meanwhile, SSDs with the same SATA III connection can reach read speeds of around 550MB/s and write speeds of 530MB/s. The SATA III connector blocks the true potential of an SSD at up to four times the speed of an HDD.

To solve the bottleneck, the high-performance SSD comes with PCIe/M.2 connection which can reach speeds of up to 1.4GB/s and even 2.2GB/s if you don’t worry about your pockets.

Therefore, if you want a very fast machine, install SSD in your computer or laptop.


SSDs are more expensive per gigabyte when compared to HDD prices. Therefore, you should prioritize between speed and storage capacity and choose the one that suits your needs.

Which one is better? SSD or HDD?

So, which one is better? SSD or HDD? All depends on your needs. SSDs are faster and use less power, but HDDs are cheaper when you need more storage.

Or you can combine both, SSD to store your apps and operating system and HDD to store your files.

That’s the comparison between SSD and HDD. I hope this article helped you! Thank you for visiting and don’t forget if you find this article useful, please share it with your friends too.
