How To Install a Second SSD: Detailed Installation Steps for Beginners 

You might be wondering how to install a second SSD and if it is okay to install a second one at all? An SSD is a solid-state drive used to increase the space of the computer and increase its performance speed.

How To Install a Second SSD

Adding a second SSD can get tricky if not done right. Let’s learn how to install the second SSD in this guide!

How To Install a Second SSD on Desktop PC?

It is mandatory to check the computer’s physical space for the SSD installation process before installing the Second SSD. Once done, do the following things:

  • Bring an SSD drive.
  • Use a screwdriver to open the case.
  • You should have an open drive bay.
  • Have an open SATA on your desktop’s motherboard.
  • Use a SATA data cable.
  • Have a power connector with you.

– Turn off the PC and Unplug It

Once you have all the items on hand, you’re ready to go. However, there’s a risk of damaging your computer’s data due to the installation process. Therefore, make sure you backup your data before doing anything. Follow the below steps to install the second SSD.

Since you’ll be working on the motherboard and opening up your CPU case, you have to make sure you turn off your computer and unplug it before the installation begins. Once done, open your computer case. There might be some static when the computer case is removed. Hence to avoid that – it is recommended to use an anti-static wrist strap

– Try To Find an Available Drive Bay

Try finding a 3.5-inch drive bay so that your installation can begin. If you cannot, then you have to buy a 3.5-inch bay along with a 3.5-inch adapter that will be used for the SSD.

– Take Out the Drive Caddy To Install Your SSD

The next step is to remove your caddy from your system so that you can install the SSD. Some computers do not have a drive caddy. If that is the case, put the SSD inside the bay and secure it in place.

– Place the Caddy Back in the Case

Now, put the caddy or the drive bay back in place and secure it firmly to avoid any issues that might occur later. The caddy might settle into its place without any problem, but you might need some kind of fastener if it doesn’t, it really depends on your computer case. Some computers secure it on their own without using a fastener.

– Find a SATA Cable Port on Motherboard

Find the SATA-cable port on your computer’s motherboard and install the cable, respectively. Once done, look for a SATA power connector. If you do not have a SATA power connector – you need to use a Molex or a power splitter.

– Plug Into the SSD Drive

After the previous step is carried out, plug in the SATA data and the power ports in your SSD drive.

Plug Into the SSD Drive

Do remember to pay attention to the orientation of the connectors in order to install them in the right manner.

– Restart PC

Now, the physical installation of your computer’s SSD is almost done. The last step is to close your PC’s case – plug in the cable and turn on your computer.

  • A window will open to initialize the disk.
  • Select GPT (GUID Partition Table), and then click OK.
  • In Windows 7, go for MBR (Master Boot Record) and then click Next.
  • Now look for the new SSD. It should be easy to spot because it’s the only unallocated drive.
  • Now, right-click on it and choose New Simple Volume.
  • Now click on Next.
  • You will have two sets of numbers, and they should be matching.
  • Then select Next again.
  • If you want to create multiple partitions on your new SSD, enter partition size.
  • Now there should be a drive letter, which can be changed from its default property. Press Next to proceed.
  • Enter a Volume Label name of your choosing. Then click Next.

How To Install a Second 2.5 Inch SSD on a Computer?

Locate one of your PC’s 2.5-inch mounts. Large 3.5-inch drive bays usually have mounting holes for fitting a 2.5-inch drive as well, or there might already be 2.5-inch mounts attached to the case’s interior chassis. Several cheaper cases also have mounting holes drilled directly into the chassis. Cables can be managed easily when the drive is already in place.

– Check the Availability of General Items

It is a little easier when you have removable mounts available because they will let you use the screwdriver outside the case with ease. You will need a crosshead screwdriver to remove the mount and affix it to the SSD before reinstalling both to the case. Every SSD needs at least three general things:

  • A power cable.
  • A SATA-cable.
  • Open physical place on the motherboard.

Mounting screws are very small, and that is why they come along with the case. In case you’ve misplaced it, it is easy to buy replacement screws online as all SSDs have the same-sized holes. Several mounting brackets secure the SSD from the underside in contrast to the mounting screws that do so from the edges. 

– Mount the SSD in Place

To place the SSD in the mount, carry the following steps: 

  • Place the SSD in the mount with the aligned holes.
  • Now secure the drive in place by using the screws.
  • Lastly, replace the mount if it’s a removable one.

– Attach the Cables

Once the SSD is in position, you can now proceed to attach the power and data cables. These cables are included with your PSU as well as the motherboard. They both use distinctive L-shaped connectors.

Attach the Cables

Be mindful that the power cable is wider than the data cable.

  • Plug the power cable into the 2.5-inch SSD.
  • Now do the same with the SATA cable. It is connected right next to the power cable.
  • Plug the other end of the SATA cable into a free SATA port on the motherboard. It can be normally found near the bottom-right corner.
  • Your 2.5-inch SSD is now successfully installed on the computer.


1. What Is the Known Average Lifespan of a Second SSD?

On average, the lifespan of a second SSD under normal temperatures and optimal usage is about ten years, after which it may or may not get faulty considering how it is used. Additionally, the lifespan of SSDs depends upon the written cycles; hence the age of the SSD depends upon the data written.

2. What Are the Things To Consider Before Installing a Second SSD?

The following points are the things one must keep in mind before installing a second SSD. Ask these questions:

  • Does your computer have enough physical space?
  • Can the motherboard support the second SSD?
  • Can the power supply unit (PSU) power the drive successfully?

3. Is It Possible to Just Plug in a Second SSD?

Sure, you can just plug a drive-in a second SSD and use it for storage (although you will need to initialize/create a partition and format it within your operating system). If you get an SSD, it’s a good idea to install or clone Windows onto it in order to get the performance boost.

4. Is It Possible To Install a Second SSD Without Reinstalling Windows?

Yes, it is possible to install a second SSD in the motherboard without reinstalling Windows.

It Possible To Install a Second SSD Without Reinstalling Windows

Here is how you can securely install an SSD without requiring the reinstallation of windows:

  • Connect/install SSD to your computer properly. Now, you just need to install the SSD alongside the old hard drive.
  • Make a clone hard drive to SSD without reinstalling Windows 11,10,8 or 7 respectively.
  • Now securely boot from the cloned SSD.

5. Can You Install a Second SSD Without Formatting It?

Yes, it is possible to install a second SSD without formatting. You can either keep the installed SSD untouched or format it as a storage drive when using it with the computer properly. It really is a matter of preference.

To let Windows choose the SSD to boot from, do change the BIOS boot order. Place the SSD ahead of other connected drives so that the computer will boot up from the SSD in the future.

6. Is It Possible to Partition the Second SSD?

Yes, it is feasible to partition the second SSD. However, for the standard user, there is no need to partition an SSD. Modern operating systems like Windows, Mac, and Linux automatically create three partitions upon installation. Also, SSDs are not prone to the same issues as traditional hard disk drives, which recommend partitioning as a best practice.


After reading this article, you will now be able to install a second SSD on your computer effortlessly.

Here’s a quick recap to revise the main concepts:

  • Use the drive bay or drive caddy to install your Second SSD.
  • Check if the motherboard has the physical space before you install another SSD. Failing to carry out this process can be risky because using another port accidentally can damage your data on the computer easily.
  • A normal SSD provides a ten-year lifespan. So, instead of installing a second SSD, install a new SSD to replace the first one. Do not forget to save your data on another disk drive.
