SSD, which one is better? Buying guide with the 12 best 2020 models

Have you decided to buy an SSD? So, this guide that we have prepared with features, comparatives and the best options by price range will help you choose the best SSD (both internal and external) for your device.

An SSD can do real magic on your computer if it is an old computer that still works under the hard drive of a lifetime, that is, an HDD. But it is also a solution to consider if you are looking to expand the memory of your device, as well as assess it if you need an external disk to store your files. Many situations, same solution.

Choosing an SSD first depends, therefore, on the use you are going to give it: it can be internal, in case you want to use it to give a new life to your computer (or simply to expand its storage capacity), and it can be external, see for example to have a backup, to play files on a TV or to dump files from one computer to another.

Since in recent years they began to fall in price to levels close to HDDs, solid storage units have become an option full of advantages: they are faster, have greater reliability and, in general, have a longer shelf life. What else can you ask for?

When we need our PC to go faster, there are times that, in the wrong way, we believe we need to increase the RAM. If we have 4 GB, we will notice an increase in speed in certain processes, but it is best to opt for an SSD since that is the real revolution.

SSD means ” solid-state drive ”, or ” Solid State Drive ”, and is one of the most important components in making the PC go much faster. It is the evolution of HDD, and its main function is to allow files to open at full speed, as well as to start the operating system (and shut down the PC) much faster.

Throughout the next paragraphs, we will tell you everything you need to know about them, but we will start at the beginning explaining what it is and what it is for.

What is an SSD?

We have already said that an SSD is a solid-state drive, and in a nutshell, it is a component of the PC that is used to store data, exactly “ same ” as a hard disk (but we cannot call it “ hard disk ” ‘because there is no’ ‘disk’ ‘inside).

An HDD hard drive has a large plate and ahead. These elements move at full speed to write and find the data we save on our PC. In these units, the physical parts disappear, since they are replaced by elements more similar to the memory modules of a RAM pad.

If you are put in technology, you will know that RAM is a volatile memory. This means that, when the power source is cut off, the data is deleted (so the RAM is emptied when we turn off the PC). However, they are based on NAND memory, a non-volatile memory that allows data not to be deleted when the power is turned off.

They do not need a battery to keep their data when it does not have a power source, and we can have it stored as an external hard drive without worrying that your data will disappear.

Next, we leave you a comparison between an HDD (left) and an SSD (right) so you can see the number of components that one system has and another.

The advantages over an HDD are obvious. By having a faster read and write speed, the files open and close much faster (this also applies to games and loading screens). E l system opens and closes in seconds, the file transfer is faster and there are several other less obvious advantages, but important.

For example, they produce less heat when there are no moving parts, weigh less (which is important in laptops), resist shock and produce no noise or vibration (again, important when we talk about laptops).

Also, if the limit of HDD hard drives has almost been reached, they still have a way to go, as they increasingly invent new ways of stacking the data and communicating it with the board with new connection paths (SATA, PCI, etc).

SSD and HDD are not incompatible

Along the next lines, we will give you more complementary information about these components, but we cannot ignore that SSDs and HDDs are not “ at odds ”. And, in the beginning, they were prohibitive due to an exorbitant price and a very, very reduced capacity.


Now you can find 480 GB models for less than 50 euros, like this one from Kingston, and although it is tempting to make a PC with only this type of storage, the most logical thing is to have a laptop that is based on storage via SSD … and a desktop with a large capacity memory for the operating system and the most used apps and a 1 or 2TB HDD for games or large amounts of files that we don’t use very often.

Why choose an SSD before an HDD

It is time to see in detail why it is a better option than an HDD, long, too. And, speed is a fundamental element when choosing it in front of an HDD, but it is not the only one.

In 2011 there might be more details that would throw us back, but now it should be mandatory on any computer, both portable and desktop since its advantages over an HDD are obvious and numerous.

Speed, the key point

We have already said it, the main reason for choosing it instead of an HDD is that an SSD has a read speed. And writing far superior to that of an HDD.

This means that both to save data and to read that data, it is faster. We are talking about a speed of about 500-550 MB / s compared to about a maximum of 150 MB / s of an HDD.

For us to understand each other, this affects the opening time of the operating system, the time it takes to turn off the computer, the speed of opening the applications and the loading times of games, as well as the download speed with lines of high-speed optical fiber.
