In general, every time you want to update your computer or simply acquire a new one, a great doubt about what kind of features you want to add to it starts to generate much better performance. One of them is what kind of hard drive to use. One of the most important parts of any electronic device is its storage capacity, that is why we must pay close attention to which unit we want to choose.
When you want to buy a new computer or you are simply mounting a computer from scratch it can be difficult to know what kind of storage unit you should choose , whether it is a HDD or SSD hard drive. In this case it is important to be clear about the use you want to give your computer and how much information you want to store there. In addition, you should keep in mind that both units can also be used simultaneously but, this will increase the cost of the equipment or its repair.
In this way, here we will explain a little about what each of these storage units is about either your laptop or desktop computer, as well as Each of the differences between the two. All this with the objective that you can choose the one that best suits your needs so that you can enjoy a team in optimal conditions and with the best possible performance .

Types of hard drives How many are there according to their access speed?
The hard drives are known by everyone as the storage units in a computer and which have a lot of specifications regarding their speed , capacity and interface. In this way we will show you what are the units that exist according to their access speed.
We can currently find three classifications of this type:
HDD (Hard Disk Drive)
HDD units are the cheapest in the market ideal for all those users who need an external or internal hard drive at a fairly affordable price . In addition, it is important to mention that this is the most traditional and least fast. Therefore if you want to have enough memory but at a low price you can purchase an HDD drive.
SSHD (Solid-State Hybrid Drive)
A unit considered very fast and with excellent results and it can be said that it is the definitive solution for users to achieve the desired storage performance on their equipment with which they can obtain better results in the computer functionality This unit is responsible for combining a solid state hard disk (SSD) and hard disk drive (HDD), in this way it was able to merge both units getting quite effective results.
All this has allowed the different storage devices to be compatible with the traditional HDD modules and thus offering a performance very similar to the storage units SSD , getting one of the most attractive storage proposals in the market in recent years.
SSD (Solid State Drive)
Known as a solid unit and is the newest model in the market with which you can get very good results, with it you can get a great speed in the readings , as well as other advantages that will make you have a better performance on your computer.
When you want to choose one of these access speeds it is important that first of all you choose the one that fits your budget, since with any of them three you will be able to achieve good results.
What is an HDD (Hard Drive Disk) and what does it have?
The HDD hard disk is the traditional rotating unit of computers and whose mission is the non-volatile storage of the equipment. That is, this disc is the one that ensures that the data recorded in the system memory does not disappear when the computer shuts down.
This storage device uses a magnetic recording system to be able to save the digital files and is composed of either one or more rotating discs all joined by the same axis and rotating at high speed inside of a metal box.
This unit has generally been the means of traditional storage used by desktops . This disc rotates at high speed while the magnetic head that is placed on a moving arm is reading and writing all the system data so that they can be saved.
In it you can save files, programs, documents, games, among others that you have on your computer. It works with a speed of 7,200 rpm , although some of these discs can reach speeds of up to 15,000 rpm.
You can see this number as part of the computer specifications. The faster the hard drive is, the greater the read and write operations will be. In this way, here are the main advantages and disadvantages of using this unit.
Advantages
Among the main advantages that you can obtain when using this unit on your computer you will find the following:
- There are many cheaper than SSDs.
- You have more storage capacity.
- Da ease of recovering data that has been lost in the system.
Disadvantages
However, using this unit also brings you some disadvantages that it is important that you keep them in mind.
- Lower loading speed , when it comes to applications and the operating system itself, which will cause the computer to work slower.
- It has a higher consumption than SSDs, therefore you need much more power.
- Causes vibrations due to the moving parts it contains .
- Cause a lot of noise.
- Due to its movement it can cause some mechanical parts to be affected.
- Its temperature is usually high , which causes it to heat up much more.
What is an SSD (Solid State Unit) and what features does it have ?
Also known as a solid state drive and is the newest storage model released. Its main function is to use solid flash memory as the main storage unit instead of spinning the disk and it is mainly characterized by offering different advantages to each of its users, especially by having a reduced size and faster speed.
With this unit you can get different benefits between them and the most important is the speed that is given to the computer, accelerates the procedure to search the data of the readings and does not have to perform the defragmentation process Whether or not the data is continuous, the units will work correctly without delays in obtaining them.
It also offers greater resistance to both shock and vibration. As well as a lower consumption, which means that you will need less power to be able to operate and finally it causes less noise than other units.
As for its operation, these SSD hard drives have two memory zones , one of them is responsible for storing all the information so that the computer is turned off , while that the other, which is much smaller, acts as a cache, accelerating all accesses of the system so that it can work much faster.
All this is handled by a governor who acts by coordinating these elements so that he functions correctly. In addition, he has several memory blocks that act as a RAID in thumbnail to improve both speed as well as prevent unit failures.
In addition, it has a wide variety of hard drives that are classified in two ways either attending to the technology used in its manufacture or attending to the connection to the PC . It also has its advantages and disadvantages which we present below:
Advantages
Using a SSD hard drive for your computer will undoubtedly offer you a large number of advantages with which your device will have a better performance.
- It has a high speed when loading the operating system, programs or applications.
- It consumes less energy , therefore , you need less power to work.
- It is much quieter since it has no moving parts.
- It is not affected by the magnetism .
- No vibrations .
- Its temperature is usually low, which prevents it from overheating .
- By not having mechanical parts this cannot be damaged by movement.
- Your cells can rewrite a limited number of times.
Disadvantages
As every device also has some disadvantages which are important to keep in mind when you want to choose this unit for your computer.
- Its lifespan is much shorter than that of an HDD hard drive.
- It has a higher price despite last much less.
- If you get a virus and your data is deleted it cannot be recovered .
Main differences between an SSD and HDD hard drive Which is better to buy?
Very surely you have the doubt of which of these two units is the best for your computer, for this it is important that you know very well the operation of each of them as well as the differences between them, in this way you can decide which of the two best suits your needs, given that one is much more modern than another.
In this way, here we present the main differences between an SSD and HDD.
Speed
This is perhaps the most important difference between both units, and that is that the SSD has a faster loading than the mechanical unit. This is how the SSD can start an operating system in at least half the time required by an HDD disk of 7,200 rpm. And in terms of reading and writing data it can triple its speed .
Therefore, being able to have a faster storage unit will give you better results when using your computer, this can become a fundamental part of choosing which of the disks to use.
The price
It is important to know that SSD drives are much more modern than HDDs. Therefore, they have greater capabilities, as well as greater advantages when using it. which will make its price much higher.
In this way, the cost of this unit can become a limitation for the user, especially considering that the price of a 250 GB SSD can have the same value as an HDD unit of at least 3TB.
The noise
SSDs being newer units and not having moving parts such as HDDs do not usually cause any noise during operation, as well as vibrations that may cause some kind of damage.
While older mechanical units do cause noise and vibration but, it is important to clarify that these noises are also not extremely hard. However, it is still an important difference between the two devices.
Durability
Another difference we can find between solid and mechanical disks is their durability , and in spite of being more modern and more advanced, their lifespan is much longer smaller than mechanics , and this is something that depends directly on the amount of data stored on it, since each of its cells only allows it to be written a certain number of times. Therefore, if you usually handle a lot of information, having one of these most current units may become a problem in the future.
Resistance
Solid units tend to be much more resistant to mechanics, this is because they do not contain moving parts, or mechanical parts that with a blow can reach break down and cause damage to the device which will cause its life to wear more quickly.
Here is the following table where you can see in detail each of the differences between these two storage units.
Comparative Table
Which is better to buy?
This will depend a lot on the use that you want to give to your computer, taking into account all of the above you will be able to realize what each one offers and what are its main benefits. Therefore, If you tend to be from people who use large amounts of documents, files, programs and require a large storage space it is recommended that you continue using mechanical units .
It is also important to consider the amount of money available, if you have a low budget and you want large amounts of storage, HDD discs will be your best option. >
However, it is important to know that using this type of unit is having a greater storage capacity and not a high speed.
But, if you are one of the users that does not usually save large amounts of information or programs and you want to have a computer with a high speed you can use SSDs, having Keep in mind that if your computer is maintained in good condition, it can take a few years to present a high speed in your operating system.
This solid unit is especially recommended for all those people who work with multimedia content or use their equipment to store different games , this will help you run much faster without any interruption.
However, today it is possible to combine both devices on a single computer, where you can use the HDD disk as a secondary unit while the SSD as the main unit of the computer. This will give you the most ideal conditions to store any type of file in the system.
