Hard drives are the heart of every computer and any information we have from the operating system to a photograph is stored on the hard drive. That is why it is so important, everything works from the hard drive.
There are currently a few hard drive options: HDD and SSD. In this article we are going to talk about the two types of hard drives and what are their disadvantages, but also their advantages.
It is very easy to recognize a lifelong mechanical hard drive or solid state hard drive, the differences to the naked eye are considerably obvious. While one is considerably larger, the other is very thin and small, about the same size as a laptop hard drive.
Mechanical hard disk, HDD
Hard drives, as I mentioned above, are computer components in which permanent information is stored, data is saved. It does not matter if the unit is turned off, the data is saved on the HDD.
They are called mechanical hard drives because they are made up of mechanical parts. In addition, they use magnetism to be able to record the data and files in it. In short, it is made up of one or more rigid disks which are joined by the same axis and they rotate at high speed in a kind of box.
Solid hard drive, SSD solid state drive
SSDs are an advance in this sense because they do not use mechanical components in themselves, but instead store all the data on microchips with flash memories which are connected to each other.
In this way, it can be said without doubt that it is a huge USD memory.
These discs are considerably smaller than the mechanical ones. Also, by not having a component that constantly rotates they are quieter. They are also considerably fast when it comes to executing files on your operating system.
In this way with a solid state disk you can start Windows in 10-12 seconds. Whereas with a mechanical disk it may take between a minute and a minute and 30 seconds. The difference is undoubtedly remarkable.
HDD vs SSD main differences
The differences are quite clear. In case the SSD has capacities ranging from 120 GB to 4 TB, while an HDD can have 10 TB of space. In addition to this, their consumption is considerably lower but they are also much more expensive than HDDs.
In the case of Solid state drives are much quieter than a mechanical disk. As for the boot speed of the OS and its applications, it can be said that with an SSD it is reduced by half. Ideal for people who work with the computer all day or several hours, saving a lot of time in this regard.
Regarding data transfer with an SSD, it remains between 200 and 550 MB / s which is a lot since a lifetime HDD can reach a maximum of 150 MB / s.
Durability is one of the most important things when we are going to talk about hard drives since one stores a lot of information on them.
When we talk about a solid disk this can be rewritten a limited number of times, lasting a few years less than a common disc which can even damage its mechanical parts with movement, so we must also be careful in that sense with a mechanical one.
Mechanical hard disk or solid state drive
¿Which is better? As you saw the main differences are three:
- The first is undoubtedly the price since an SSD is much more expensive than an HDD.
- Also, HDDs have much more capacity than an SSD.
- The good thing about an SSD is that they are considerably faster And once you start using a computer that has a solid state drive, you never want to go back to an HDD again.
For most people a 4 TB space (the maximum currently available on SSD) is more than enough. In many cases, what is recommended is to have an SSD of approximately 250 GB to have the operating system and programs that are most used. Keeping a HDD connected to save data as a secondary disk.
Keep in mind that currently a 250 GB SSD can be worth the same as a 4 TB HDD, to give you an idea of the prices.
In case you like your computer to work very quietly, having a solid state disk is highly recommended since having no mechanical parts or anything that rotates like an HDD causes less noise and no vibrations.
As I mentioned above, what you can notice a considerably huge difference is in speed. A computer that has an SSD can boot the OS in less than half. Even in a matter of very few seconds (15 or less) when a mechanical disk can take even more than a minute to start the OS.
Pro and cons of an SSD
The problem appears when we talk about durability and is that the duration of the solid state disk depends on the amount of data you write on it. The point is that each cell in a flash memory bank can be written a very limited number of times.
Teach Report conducted a study with a Samsung 850 Pro SSD where they confirm that it can last up to 2500 Terabytes. This can be translated into a little over eight years or so.. Although as I said above it depends too much on the use that each person gives to the hard disk.
Then we can conclude the issue of durability in which the SSD will depend a lot on the use you give to it when in the case of the HDD the main problem comes from part of the blows or even movements when it is working. Reducing its useful life and even being able to damage data and even lose it.
There are many tools capable of monitor the health of hard drives for both SSD and HDD. In this way you can keep abreast of its health and know exactly how long its useful life is.
In these cases it is always ideal to have a backup of the most important data in the cloud, so as not to have any kind of data loss problem.
Conclusion: Which disc should I choose?
As we mentioned a little above, it is best to try to combine both hard drives in order to have where to save a large amount of data (especially for those who download a lot of things from the internet, for example) and have the most used operating system and programs on the SSD.
For those people who jplay video games, edit multimedia content, or work long hours in front of the computer. Having an SSD can save you a considerable amount of, even hours at the end of the day.
Keep in mind that with an SSD you can even “revive” an old computer. Since being much faster you do not need to buy new components for it to work faster.
Many times exchanging the mechanical disk for a solid state disk you may find yourself in a pleasant surprise, with a computer that has been operating in a much more agile way for many years.
But I repeat: it is best to try to combine both hard drives, leaving even a small one in solid state for the OS and a mechanical one to save data, it is the most recommended.
