Differences between internal and external hard drive

The main difference between an internal and an external hard drive is the mobility it offers. The reality is that both have the same operation and require the same components to function. However, external hard drives are covered with a casing that allows them to serve anywhere.

The ultimate purpose of each is not the same either. Internal hard drives, in addition to being used to store personal data, are used to install the operating system that will allow you to use your computer. On the other hand, external hard drives are often used exclusively to save information or make backup copies.

The choice between one type of storage or another will depend, mostly, on the use that you are going to give it. Obviously, if you need to transport your information on frequent trips or trips, you need an external one with reduced dimensions. If your intention is to make backup copies of the content of your computer or have personal information in one place, as in the case of a desktop computer, a larger external hard drive or an internal one that complements the main one are the best option. 

Finally, another big difference is durability. Since internal hard drives are not portable, they tend to withstand the test of time better. On the other hand, external hard drives, especially those that are designed for regular movements, wear out more easily, are more likely to have connection port failures and can suffer shocks and drops.

Types of hard drives

There are different ways to classify the different storage devices. Next, we propose three.


The technology used in each storage device is the first differential fact. On the one hand, you have mechanical hard drives, which use magnetic drives and drives to save and read data. They are robust units, designed for desktops, servers or NAS. They tend to offer a good price-performance ratio, but are slower as they rely on the physical spin of the disks to function.

SSDs are the perfect alternative for those looking for a lot of speed. They use a flash memory system that does not require a physical drive. They are mistakenly known as hard drives, although their most appropriate name is solid state drives. Its design follows the structure of mechanical hard drives to fit in standardized locations. However, the reality is that they require less space. They are more efficient and faster, but their price-performance ratio is worse.


The location also defines the typology of a storage device. We can distinguish up to three different locations. First of all, those that are installed internally. They are all those that go inside the body of the computer, be it a laptop or a tower. They are used to store data, but also to install the operating system or applications. It is important that they are capable of running at high speed, especially if high performance is required. They can be SSD or HDD.

Second, fixed location external hard drives. They are usually large devices, which are not designed for mobility, although they are located outside the computer. They connect via USB and, in the case of NAS, via network cable. Among its virtues we find greater durability and a large storage capacity. There are SSD and HDD, although this last technology is the most used.

The third category is made up of external hard drives. The main advantage is that they have a moderate size and low weight. They are perfect for taking files from one place to another or transferring them between different computers. Most are SSD.


We put an end to this section in which we analyze the different types of hard drives with connections. The most used port in internal hard drives is SATA, although there are also options with SCSI and SAS, focused on servers and NAS. Today SATA3 is the fastest interface, with transfers of up to 600MB / s.

If we talk about external storage, the most common connection is USB in version 3.0. Some options also offer USB 3.2 , which raises the data transfer rate to 2.42 GB / s. As for the NAS, generally, they access the local network or the Internet through an Ethernet cable, connected directly to the router. In this case, transfer speeds vary considerably depending on various factors.

Is it worth buying an SSD versus a normal hard drive?

Before answering this question dogmatically, it is necessary to understand what differences are between a traditional hard drive and an SSD. The former use a magnetic system to record the data. When the user or the operating system makes use of the storage, several metal plates rotate while a head reads or writes the necessary information. The faster the disks spin, the higher the read and write rate is achieved.

For its part, SSDs do not require physical movements to read or write data. Rather, they use microchips with various flash memories that are interconnected with each other. Actually, this type of storage is exactly the same as that used in memory cards and USB sticks.

After knowing these data, it is much easier to obtain an answer to the question we posed. In short, in most cases it is more interesting to opt for an SSD than an HDD, or hard disk. The former is faster and quieter. In return, it is an option that usually offers less capacity at a higher price. In light of this, a common setup is to combine both drives, using the SSD for system or application data and the HDD for storing a lot of personal information.

Buy a normal hard drive or NAS?

NAS or traditional hard drive

In order to evaluate the need to acquire a NAS, it is necessary to know what exactly it is. NAS stands for  Network-attached storage, that is, network storage. NAS are made up of two main elements . The first is storage, which includes the use of one or more traditional hard drives located in bays. The second is the network interface, which is responsible for enabling remote access to all the information on the disks. Please note that in most cases, hard drives used in a NAS need to be purchased separately.

In which cases is it advantageous to consider acquiring a NAS? Whenever you want remote access to your information. The most common use of this type of device is the creation of a private or personal cloud, in which your files are available from anywhere, but physically hosted in a place that you own. They are also used to store multimedia content and allow it to be played on televisions or stereo systems.

In which cases is it advantageous to buy a traditional hard drive? In all those that do not require remote access to your information. This will mean a considerable saving, both when making the purchase and in energy consumption. And, if there is certain information that you want to have available anywhere, you can use more effective solutions, such as memory sticks or small external hard drives.

Tips and Factors to Consider When Buying a Hard Drive

Depending on its characteristics, each hard disk has a different purpose. In the following sections, we will take into account the most differential details between the various options on the market. Thus, we will help you define which is the best option for you. External hard drive are also best for backup purpose.

Internal or external use

We already pointed out the main difference between albums in a previous section of this article. It is about whether they are internal or external. The former are essential as the main storage device, where to host an operating system and all those data linked to it. The latter are usually a good complement to create backup copies and save personal information. In addition, they offer the possibility of using them in more than one team and during any trip. If, in your case, you don’t need to transport your data from one place to another, internal drives are the most recommended. But, if the idea is to have your information anywhere, think about acquiring a moderately sized external hard drive.

Physical size

Hard drives can also be differentiated by their size. Today, the user can choose between 2.5-inch drives, frequently used in notebooks and small external devices, and 3.5-inch drives, installed mainly internally in desktop computers. Again, the end use and availability you expect of your files are determining factors when choosing.

Storage capacity and speed

The capacity and speedthey also define the different types of discs that are currently marketed. In the first case, it can be very limited, 64 or 128 GB, or really generous, 10 or 15 TB. In terms of speed, there are slower drives, with read and write speeds of about 100 MB / s, and very fast, with rates of up to 1 GB / s. Your budget will be decisive here, since the fastest and highest-capacity options are more expensive. For occasional uses, such as infrequent backups, a medium transfer rate disk will suffice. Similarly, if you are going to use the disk to install the operating system or to constantly copy data, it is worth opting for a fast hard disk. Regarding the capacity,


Connectivity on a hard drive can be divided into two sections. First, the interface you use to connect to the computer. In the case of internal hard drives, these are often linked over SATA. If we talk about external drives, the connection is usually via USB. In both cases, it is important that you have the latest versions of each interface, such as SATA3 or USB 3.0. 

Second, there are network-connected options on the market. These are always external and are known as NAS disks. One of its main functions is to create a private cloud, making user information accessible from anywhere with the only requirement of having an Internet connection. It is necessary to indicate that, although they are external disks, they are not intended for mobility. However, they favor it, since they enable remote access to any file hosted on the disk.
