The best hard drives are certainly not at the level of the best SSDs, but they still offer significant advantages too. For example, the best hard drives are much more affordable and capacious. Also, a good hard drive can be useful as an additional drive or even as an external measure, especially if you have a lot of data to backup.

When you are in the market for the best hard drive, you need to consider what you want to get out of it. If you want to expand the storage space for your PS4 or Xbox One, a 2,5-inch drive or even an external hard drive will be perfect. On the other hand, if you have one of the best gaming PCs and need somewhere to store all those games, a 3,5-inch drive rated at 7.200rpm should be your best choice and may be one of the best drives. rigid for you.

How to choose an internal hard drive

What is a hard drive? The internal hard disk is an internal element of the computer that serves to store data by reading and writing them quickly. It is just as important as the processor and RAM, as it stores data, programs and operating systems.

It consists of a metal box with magnetic plates that contain data and rotate thanks to a motor supported by a central pin.

Before going into the list of hard drives currently available on the market, let's see what are the technical characteristics to take into account before buying one.


Almost all hard disks on the market can be connected to a PC via an interface SATA 3.0, which allows performance up to 6 Gbps and is also compatible with previous standards, even if the read and write performance occurs at the maximum speeds of the 1,5 Gbps and 3 Gbps standards.

The other interfaces are the SCSI: o Small Computer System Interface, used in the server environment and concerns PCs with higher performance and higher costs, and the IDE or ATA, older requires the use of a power supply to be connected to the hard disk.


Hard drives have different formats. they can be distinguished in 3,5-inch and 2,5-inch drives. The former are used in desktop PCs, while the latter are mounted on laptops since they have smaller dimensions and lower power consumption.


If you have to make a standard use of the PC, a hard disk with 1TB is more than enough. If, on the other hand, you need to use the hard drive to store multimedia files or for large backups, you will need about 3TB or 4TB. For laptops I recommend 500GB is more than enough. If not, you can always use external drives such as external hard drives or USB sticks.


La rotation speed of a hard disk is indicated by the abbreviation rpm and specifies the number of revolutions per minute of the dishes. The higher the rotation speed, the faster the hard disk speed will be. I recommend getting one that travels at 7.200 rpm, even if the minimum on the market is 5.400rpm.


It is the memory where the recently read or written data is temporarily stored from the hard disk. The wider it is, the better the information access times will be. It usually has a space of 32MB, 64MB or 128MB.


Other items to consider before buying an internal hard drive is the data transfer speed, expressed in Megabytes per second (MB / s), the data access time, indicated in milliseconds (ms) and the noise level, indicated in decibels (dB).

In addition to traditional (mechanical) hard drives, we have SSDs (solid state), which are more expensive and less noisy, and hybrid hard drives, halfway between SSDs and HDDs. Then there are NAS (Network Attached Storage) Hard Disks which are small PCs that allow you to share files on the network through the use of one or more hard disks at the same time. They are usually identified by the abbreviation "NAS" and it is not advisable to mount them inside PCs. For more details you can read this article: Best NAS for home and office.
