- 5 Summary
- The internal hard drive is a piece of hardware designed to store all data and software found in a computer. It is built directly into the motherboard, which is another essential element of any electronic device.
- This component generally consists of several plates connected to a spindle that writes and reads the elements through its heads when spinning at high speed. This speed is variable and will determine how fast the reading and writing are.
- The storage capacity of an internal hard drive is measured in gigabytes or terabytes – the largest amount of stored data available. This is the factor that most influences the decision of buyers.

Shopping Guide: Everything You Should Know About Internal Hard Drives
What is an internal hard drive exactly?
Nowadays, internal hard drives are present in virtually all electronic devices: computers (desktop and laptops), cell phones, tablets, TVs, and video game consoles, among others. This is why they are designed to store a wide variety of files, from photos, videos, and audio files, to software and video games.
What types of internal hard drives are there?
For this reason, their structure and components are also distinct. HDDs have one or more disks linked by a spindle and heads that write and read the contents as the spindle moves. SSDs, on the other hand, have no moving element; instead, they store data in non-volatile memory, without heads or other mechanical components.
How does an internal hard drive work?
Since they lack any kind of mechanical element, solid-state drives store data in microchips with flash memory. Instead of the heads found in HDDs, they integrate a processor that executes the reading and writing functions, increasing the efficiency and avoiding potential mechanical failures.
How is the speed of the hard drive determined?
Solid-state drives, on the other hand, are much faster as they don’t rely on a mechanical component. In that regard, the speed is expressed in megabytes per second (MB/s). Since there is no rotation to measure, this value corresponds to the speed with which the data passes through the interconnected microchips of the disk. This is typically how flash memories operate.
What is the hard drive interface?
The two most common interface types are the Serial AT Attachment (SATA) and the Peripheral Component Interconnect Express (PCIe). There are multiple variations of the SATA interface, whose technology has evolved over time. Therefore, you can find SATA 1.0, SATA 2.0, and SATA 3.0 models, the latter being backward compatible with older devices and offering higher speeds. The PCIe interface guarantees an even faster speed.
What is an internal hard drive cache?
Measured in megabytes, this technical characteristic varies within a reasonably wide range. Again, you will notice significant differences between internal HDDs and SSDs. The former will offer anywhere between eight and 256 megabytes, while the latter generally start around 32 megabytes of cache memory.
How can I know if an internal hard drive is compatible with my device?
Size can be extremely restrictive and is often decisive since it is all about space: it either fits or it doesn’t. The other two factors are more flexible, in the sense that a SATA 3.0 disk is compatible with a PC that doesn’t support that interface as long as it supports SATA 1.0 or 2.0. That being said, note that the performance will not be optimal, and you won’t be able to make the most of your internal hard drive.

We have now answered the most frequently asked questions regarding internal hard drives, and we have introduced you to some of the most popular models currently available on the market. Before we end our article, let’s delve into the features that you need to take into account when making your purchase. These vital shopping criteria will help you identify the model that matches your needs and meets the characteristics of your computer:
As we mentioned at the beginning of our guide, this is often the first factor that people analyze when choosing a new internal hard drive. It is also a good tie-breaking criterion if you are hesitating between several similar models. This will directly influence the number of files and programs that you can store on your device, which is why you cannot overlook the storage capacity.
Storing photos, Office documents, and basic software and programs isn’t the same as having video games, movies, and other large files such as presentations or works in design programs. For this reason, this criterion is linked to the type of user and device – computer, tablet, or gaming console, among others – in which you will add it.
As we have just mentioned, size is particularly crucial if you are looking for an internal hard drive to integrate into an existing device. It won’t matter as much if you are building your computer from separate components as you can adjust it to your liking. Internal hard drives come in different sizes and physical forms that may prevent you from installing them in your device.
Keep in mind that the size of a hard drive in a desktop computer (mostly 3.5 inches) differs from that of a laptop computer (2.5 inches). Besides, the models found in the most popular video game consoles also generally measure 2.5 inches. Don’t hesitate to consult the manufacturer of your electronic device if you have any doubts.
The compatibility between the internal hard drive and your device is absolutely critical. As we discussed in the previous criterion, the size is a factor of compatibility that you need to evaluate. However, it isn’t the only one. Besides the size, there are two other vital aspects: the operating system with which your device operates, and its connectivity.
If you need a hard drive to add to an old computer, for instance, a Serial ATA III model will be of little use to you. While it should work without any problem, you will never be able to take advantage of its reading and writing speed with a device that was built during the SATA I series era. Regarding operating systems, on the other hand, most internal hard drives are now compatible almost universally.
Reading & Writing Speed
This factor will determine how long it takes for your internal hard drive to store and read files when you access them. This is essential because we are no longer used to waiting for our electronic devices to perform these tasks as they are becoming faster and faster. As you now know, the measurement parameter varies depending on the type of model you opt for.
In the case of HDDs, the speed is measured in revolutions per minute (rpm) – 7,200 being the most common value on the market. You should aim for a model that matches or exceeds this value. Since SDDs use flash memory, the unit of measurement is the megabyte per second (MB/s). As you can imagine, a higher speed also means a higher price.
Also known as the buffer of the hard drive, the cache is the space reserved for the storage of the digital files that you access most frequently. In that sense, you have to take into consideration the types of files you open more often.
Knowing the range of values is key to picking the cache that you need for your electronic device. The higher the capacity is, the more information you can store in the buffer. In the case of HDDs, the cache will generally range between eight and 256 megabytes; for solid-state drives, it starts at 32 megabytes.
Throughout our article, we have tried to synthesize the most relevant information regarding the essential piece of hardware that internal hard drives are. We have explained the primary technical characteristics and compared the leading models available on the American market. Our last section introduced you to the shopping criteria to keep in mind when looking for the perfect model.
We hope that you found our shopping guide on internal hard drives helpful and informative. If that’s the case, feel free to give us your opinion by leaving a comment in the section below.
