We are all in a situation where we feel that our newly purchased computer has enough storage space to store all the files in the world. But before you know that, the File Explorer bar, which shows the space used and the remaining space, changes from blue to red. Then you need to decide which files to keep and which are not important enough to save on your system. 

However, if you are tech-savvy and can afford some money, another way to tackle the problem is to get additional storage space. You can choose to replace your computer’s hard drive with a new, larger capacity hard drive or buy an external hard drive. So how many hard drives can a pc have? If I have limits, how can I check my PC limits? There are answers to these questions and more. 

External Hard Drives:

The external hard drive is the most practical solution for many because it doesn’t require any installation on your computer. But, the downside is that you have to carry extra luggage, and it is very vulnerable to knocking. It can be expensive. Replacing the internal hard drive provides a more permanent solution. However, you will experience the stress of transferring files from your old hard drive to your new hard drive.

There is another option that combines the best of the above two. Permanently adding another hard drive to your computer will result in another internal hard drive. This means that you don’t have to transfer files from your old hard drive to your new hard drive, and you don’t risk losing your new hard drive.

How Many Hard Drives Can I Have On My Pc?

Your PC can actually use multiple hard drives, but the extent to which you can increase the number of hard drives on your PC depends on your motherboard.  This allows more hard drives to be installed on your computer. You will find them in laptop and desktop computers, gaming consoles, servers, and whatnot. 

How To Tell How Many Hard Drives I Can Have?

Before thinking about investing in an additional internal hard drive, you need to answer the following questions: How many hard drives can I have on my PC? To do this,  open the case and check the motherboard. However, if you are unfamiliar with doing this, it is advisable to oppose it as it can accidentally damage your computer.

Another way to find out how many hard drives you can have on your PC  is to go into the BIOS setup. BIOS stands for Basic Input / Output System and is the main boot program for your PC. Such a program is needed to boot a computer system and is usually built into the system as a chip on the motherboard.

Therefore, the BIOS setup shows the SATA ports available on the PC motherboard. To access the PC’s BIOS,  press the default BIOS key while the system is booting. The key depends on the manufacturer and can be the F1, F2, F10, F12, or DEL key. If you are using the Windows 10 operating system, you can also access the BIOS from the advanced recovery settings in the boot menu.

 If you’re unhappy with the number of SATA ports available on your PC’s motherboard, you can always increase it by purchasing an expansion card. However, these cards must be supported by your PC’s operating system. If not supported, the motherboard will not work with the card.

How To Install A Hard Drive In A Gaming Pc?

Disconnect the computer from the power supply:

To install the second hard drive on your computer, you first need to decide where to mount it on your computer. If your PC is a desktop PC, this may not be an issue as you have enough storage space, and you only need to determine where to attach the bracket that holds your hard drive. If you use a laptop, you may need to sacrifice your DVD drive for your new hard drive. 

Disconnect your computer from power. This is, of course, essential for safety. I don’t want to open an electronic device while it is still connected. Unscrew the rear case and disconnect the drive cable. Most drives have two cable connectors, data, and power. Data cables typically have a ribbon cable and a wide tip, and power cables have red, yellow, and black wires connected to a white tip. 

Remove the DVD drive:

Unscrew the drive and unscrew it or slide it out (depending on the manufacturer). If you are using a desktop, you may not need to remove the DVD drive. Install the new hard drive mounting bracket and secure it with screws. Installing and connecting the hard disk: Slide the hard disk into the internal holder and secure it with screws. Loosen the cover and reconnect the power supply. The rest of the setup steps require turning on or reconnecting your computer.

The BIOS setup:

Switch on your PC and enter the BIOS. Look for a “Setup” tab or a “Hardware” tab and select (you will have to navigate with the keyboard). This will bring you a list of the hardware connected to the motherboard, and the new hard drive should be included. Select the booting sequence order and then Save the setup and exit. This should make your computer automatically restart.

If you can`t find the hard drive in the BIOS, switch off the PC and inspect the hard drive`s cable connections again. Also, ensure that the “Autodetect” option is enabled.

Format the hard drive:

 you will have to format the hard drive into a file system readable by your computer. If you intend to use Windows system files on the new drive, format it to NFTS. However, if you only want to store data, you can format it to exFAT or FAT32.


The question asking “how many hard drives can be used in your PC” is probably because you need to increase the amount of memory available on your PC. There are many ways to achieve this, but adding a hard drive provides another creative option. However, it may be better  to leave the job to a professional.
