How Many SSDs Can My Motherboard Support?

SSDs becoming more common among the computing masses as they are becoming more affordable and reliable.

SSDs, or Solid-State Drives, store data on interconnected flash memory chips rather than spinning platters like HDD. This means that instead of using mechanical parts to retrieve information, it can be done almost instantaneously with an SSD. As a result, SSDs are faster, more reliable, lighter in weight, and consume less energy than HDDs.

Additionally, many laptops and PCs come with both an HDD and an SSD giving users the best of both worlds- large storage capacity for documents and photos with fast performance speeds for applications.

Now, if you are wondering how many SSDs your motherboard can support, we will answer that question in detail in this article.

How Many SSDs Can My Motherboard Support?


Answer: The number of SSDs you can put on a motherboard depends on the number of SATA ports available on the motherboard. Generally, most motherboards have at least four SATA ports, allowing you to install up to four SSDs. Some better motherboards may even offer more than four SATA ports, thus enabling you to add additional storage by adding extra SSDs.

It is important to check your motherboard’s specifications before buying an SSD as some motherboards may not support higher-capacity drives.

Additionally, if you are looking for faster performance with your SSDs, then it is recommended that you opt for NVMe-based M.2 slots which are available on some motherboards and can deliver superior speeds compared to traditional SATA connections. Ultimately, the best way to know how many SSDs your motherboard can support is by checking its specifications.

Acknowledging the fact that space is always a concern, some motherboards feature multiple M.2 slots for installing NVMe-based SSDs which offer significantly faster speeds compared to SATA connections.

There is also a way to increase the storage capacity of your motherboard, which is by using a SATA controller card or expansion card.

An Expansion Card Is a Good Solution

A SATA expansion card is an add-on peripheral device that adds additional SATA ports to your motherboard, allowing you to add extra internal drives.

This can be very useful for users who want more storage, but whose motherboard does not support the number of SSDs they need.

Factors That Affect the Number of SSDs On A Motherboard

Motherboard Size

Motherboards come in different sizes: ATX, mATX, and ITX. The size of the motherboard will determine how many SSDs you can fit on it

ATX motherboards are usually larger and come with more SATA ports, thus allowing for more SSDs to be installed than an ITX board would.

Motherboard Age

Older motherboards generally have fewer SATA ports than newer ones, so if you are using an older motherboard, you may be limited in the number of SSDs you can install.

CPU Lanes

The number of CPU lanes your motherboard has will also determine how many SSDs can be supported.

CPU lanes are the channels that connect the processor to other components, such as storage drives. If a motherboard has more CPU lanes it is likely to have more SATA ports, thus allowing for more SSDs to be installed.

Benefits of Having Many SSD Storage

Increased Storage Capacity

One of the best benefits of having many SSD storage is its increased storage capacity. With an SSD, you can store more data without taking up much physical space.

The capacity contained in these devices is always increasing, making them far superior to traditional hard drives in terms of being able to store large amounts of data.

SSDs also save users from the hassle of worrying about where to house their files as they don’t need as much space as a hard drive does. This feature gives users peace of mind knowing that their data will always be close by and never outpace the current level of storage that they possess.

Improved Performance

Adding multiple SSDs to your system can also improve the overall performance of your system. With a single large SSD, you will likely experience better boot times, faster loading speeds for games and applications, and improved data transfer rates.

Adding multiple smaller SSDs gives users the ability to spread out their workload across different devices, thus improving performance even further.

By leveraging this feature, users can rest assured that their system will always be running at its peak level of performance.

Improved Reliability

Finally, having multiple SSDs in your system can help to improve its overall reliability.

By spreading out the data across multiple devices, you reduce the risk of a single failure taking down your entire system. This helps to ensure that if one drive fails, the other drives will still remain functional and allow you to access your files without any major disruptions.

Using Portable SSD

Portable SSD

If by any chance, you already occupy all the slots of your motherboard, you could still increase the storage capacity by using portable SSDs.

Portable SSDs can be connected to your system through USB and offer great speeds with decent capacity. They are also very easy to carry around, so they can serve as an ideal solution for people who need a lot of data on hand but don’t want to lug around multiple hard drives. However, the downside is that they are connected externally, so they may not be as fast as an internal SSD.

Also, some people will get annoyed seeing more cables in the back of the motherboard, spoiling the aesthetics.


You probably have an idea now of how many SSDs you can fit on a motherboard based on the factors mentioned above.

We also provide a solution to increase the SSD capacity, which is by making use of SSD Expansion Cards or using portable SSDs.

I hope this article has been a helpful guide in helping you understand how many SSDs can be installed on your motherboard and what solutions are available to increase your storage capacity.
