Buying Guide

Purchasing an internal hard drive is not an easy task today, as there is a huge variety of brands and models on the market, and they do not have simple specifications to understand for someone who is a layman in the field.

For this reason, we have prepared the Buying Guide below so that you can decide more easily on which internal hard drive is the best according to your objective.

What is an internal hard drive?

A hard drive, also known as a hard disk, is used to store files, programs, games, etc. This equipment basically works as a kind of memory inside the computer.

This is where your computer information is saved, which is why it is so important, because if its functioning is compromised, you will have problems accessing your data.

What are the advantages and disadvantages of the internal HD?

Are you in doubt whether to buy an internal hard drive or not? So pay attention to the advantages and disadvantages that we will list below.

One of the benefits of having an internal hard drive, is that its storage capacity is usually greater than that of external hard drives, and therefore they are indicated for those who need a lot of memory space.

In addition, the internal hard drives are always connected to your computer, which means that you are not at risk of forgetting it somewhere, as can happen with the external hard drive.

Finally, a benefit that many people take into account is that the internal hard drive is not at risk of falling and malfunctions, since it is inside the computer or console.

On the other hand, the internal HD is not portable, so you will not be able to connect it on several different devices or take it on trips.

They require some technical knowledge for their installation, contrary to what happens with external hard drives, which should only be connected to the device.

Check below a table with the advantages and disadvantages of an internal HD:

What is the difference between an internal HD and SSD?

SSD is an innovative technology that has gradually taken the place of HD on computers and consoles.

HD is a technology with a lower cost for consumers, and has a reading performance slightly lower than SSD. As the price per gigabyte of HD is lower, it is indicated for those who want to have enough space without having to spend a lot for it.

SSD, in turn, has greater durability than HD, in addition to having a better performance and being more compact. For now, because it is still a relatively new technology, SSD is still more expensive than HD.

Check the table below for the main differences between SSD and HD:

How much?

A HD can cost between R $ 70 and R $ 4,000, and the value of it is usually associated with its capacity, because the bigger it is, the higher the price of the HDD.

Therefore, an account that many people do before purchasing an internal hard drive, is to divide the total price of it by capacity, to get an idea of ​​how much the price per gigabyte costs. So you can better compare the models, and see which one has the best cost benefit.

Where to buy?

You can find an HD for sale online at sites like Amazon.

When buying through a website you have access to a larger variety of Hard Drives, so you have more choice, in addition to finding the best deals.

If you choose to buy in a physical store, look in places specializing in computer products, or even in department stores that have an area of ​​electronic equipment, such as Casas Bahia.

Purchasing criteria: What are the characteristics to evaluate an internal HD?

An internal hard drive has certain characteristics that must be observed before your purchase, so that you can purchase this product with the confidence of being doing a good deal.

Below is a list of the factors to be analyzed:

  • Capacity
  • Size
  • RPM
  • Cache

Below we will detail the most important features so that you can choose the most suitable equipment for you.


One of the main characteristics that must be observed in an internal HD is its storage capacity, especially if you intend to use your computer for games, which normally take up a lot of space.

The capacity you choose will depend mainly on the amount of money you are willing to spend, and the goal you want to achieve with the computer, whether it is for games or just to access the Internet.

The most common is to find 1TB, 2TB or even 4TB hard drives, and the greater the capacity, the more expensive it will be.


The size of hard drives is usually between 2.5 and 3.5 inches, and the choice will depend on the internal space of your computer, because, if it is thinner, you should choose the smaller hard drive, but, if your PC is more robust, you can choose the larger HDD.

So it is important that you evaluate the size of your device well, and that, if possible, talk to a technician specialized in the subject to find out which internal HD size to choose.


The acronym RPM stands for revolutions per minute in English, or revolutions per minute in Portuguese, and is related to the number of turns the disc takes in one minute.

This is important because the amount of spins on the HDD’s internal disk can be reflected in higher reading speeds. Typically 2.5-inch hard drives have 5,400 RPM, while 3.5-inch hard drives have 7200 RPM.

Cache (Buffer)

The cache is a temporary storage memory, and it holds some important data that is used frequently. Without it the performance of computers is very limited.

Opt for an internal hard drive that offers greater buffer space, so that you can have a hard drive with a better speed. The cache is usually 16, 32 or 64 MB.
