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 on 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.
What is an internal hard drive?
Check the table below for the main differences between SSD and HD:
|Price||Higher for being a new technology||Cheaper because it is more widespread in the market|
|Performance||High performance||Performance is not as good as SSD|
|Durability||Discharged for not having mechanical functioning||It is not as high as the SSD|
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, as 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.

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 that you are getting a good deal.
Below is a list of the factors to be analyzed:
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 largest 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 number 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.
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.
