Things to Know About SSD and HDD: Comparison, How to Choose

With the advancement of science and technology, hardware manufacturers are increasingly developing to improve the quality of hard drives. Before learning about the advantages of each type of hard drive, you should clearly understand what SSD and HDD hard drives are ?

I. SSD (Solid State Drive)

Structure and operating principle : SSD hard drives use flash memory to store data, without moving mechanical parts, helping to increase data access speed and reduce the risk of damage due to physical impact.

Advantages of SSD :

1. Fast data access speed : SSD allows reading and writing data at much faster speeds than HDD, helping to boot the computer and open applications in a short time.
2. Higher durability and longevity : Because there are no moving parts, SSDs are less susceptible to vibration or shock.
3. Low Power Consumption : SSDs are more energy efficient, helping to extend battery life on mobile devices.
4. No noise during operation : Due to the lack of mechanical rotation, SSDs operate more quietly.

Disadvantages of SSD :

1. Higher cost than HDD : For the same price, SSDs usually have lower capacity than HDDs.
2. Limited Capacity : SSDs with large capacities are still quite expensive, making large data storage difficult on a limited budget.

II. HDD (Hard Disk Drive)

Structure and operating principle : HDD stores data on rotating magnetic disks with a moving read-write head to retrieve data. This technology has been around for a long time and has been improved over many decades.

Advantages of HDD :

1. Cheaper price : HDDs are much cheaper than SSDs, making it easier for users to own large capacity hard drives at low cost.
2. Large storage capacity : HDDs are popular with capacities up to several TB, suitable for storing large amounts of data such as videos, photos and large files.

Disadvantages of HDD :

1. Slower data retrieval speeds : HDDs cannot compete with SSDs in terms of speed, resulting in longer load times and lower performance.
2. Lower Durability : Due to the mechanical parts, HDDs are susceptible to damage from impact or vibration.
3. More Power Consumption : HDDs require a lot of power to spin the disk and move the read-write head, which is not ideal for mobile devices.
4. Noise : When operating, HDDs can make noise due to moving mechanical parts.

Above is a basic understanding of the two types of hard drives to help you grasp the basic information about what you need to know about SSD and HDD hard drives . From there, you will understand how to operate as well as the advantages and disadvantages of each type of hard drive.

II. What are the advantages and disadvantages of SSD and HDD?

It is undeniable that thanks to the improvement, SSD hard drives have superior features compared to HDD hard drives . Some advantages of SSD are as follows:

1. The operating system has a fast boot time of just a few seconds.
2. Working speed, data processing, and information output are extremely fast.
3. Downloading and installing software is optimized for speed.
4. Security features and shock resistance are highly appreciated.
5. The system operates very smoothly, with virtually no noise.
6. Fast heat dissipation and cooling capabilities so the computer will not get hot when working for a long time.
7. Large data transmission bandwidth helps improve computer performance.

Corresponding to the above features, the price of SSD hard drives is more expensive than HDD . In addition, the limitation of SSD hard drives is that the capacity is only up to 1TB for laptops and up to 4TB for desktop computers.

Besides the advantages and disadvantages of SSD hard drives , you should also grasp some characteristics of HDD hard drives . In general, HDD hard drives are low-cost, suitable for many people's financial conditions.

The next advantage is that HDDs have a relatively high capacity: 500GB and up to 2TB for laptops and up to 10TB for desktops. The disadvantage of HDDs lies in the mechanical components. Over time, the internal motor slows down and the storage capacity also decreases. Not only that, the internal components are susceptible to external factors due to poor shock resistance.

III. How to check SSD or HDD hard drive

Besides the advantages and disadvantages or things to know about SSD and HDD hard drives , you must learn how to test them. The general formula for testing the stability of a hard drive just needs to follow these steps:

Step 1: Press the Windows + S key combination

Step 2: Type ' Optimize ', the Media type box will appear

Step 3: Go to Media type to check if the laptop hard drive is SSD or HDD.

You can also try another way by following these steps:

Step 1: Right click on My computer/This PC -> Manage.

Step 2: To check the capacity of your hard drive, select Disk Management.

At this time, the hard drive specifications will appear and you can search Google to know if the computer uses SSD or HDD.

IV. Should I choose SSD or HDD?

After understanding the things you need to know about SSD and HDD hard drives , you will wonder which type to choose. In fact, this depends on your purpose of use. If you just need a computer for studying, storing documents, and entertainment, then HDD is for you. In particular, students, pupils or civil servants often prefer HDD because of its affordable price and good features.

On the contrary, if you are a graphic designer, IT person, gamer, there is no more suitable choice than SSD. Because the fast processing speed of the hard drive will help the computer work more smoothly and efficiently. Therefore, you need to consider what you buy the computer for and then decide to choose SSD or HDD.

V. Conclusion

SSD and HDD both have their own advantages and disadvantages, depending on the needs of the user, they can choose the appropriate hard drive. If you need high speed and good performance, choose SSD. If you need large capacity at low cost, HDD is a reasonable choice. Combining both will help optimize computer efficiency, bringing the best experience to the user.
