Are you looking to build a new computer or upgrade your existing one? If so, you may have come across the term “M.2 slot.”
M.2 slots are a type of interface that allows you to connect solid-state drives (SSDs) and other devices directly to your motherboard. But did you know that there are different types of M.2 slots? In this article, we’ll explore the different types of M.2 slots and what they are used for.

What is an M.2 Slot?
Before we dive into the different types of M.2 slots, let’s first take a look at what an M.2 slot actually is. An M.2 slot is a small, rectangular interface that is typically found on modern motherboards. It is designed to support high-speed data transfer rates and can be used to connect a variety of devices, including SSDs, Wi-Fi cards, and Bluetooth modules.
The Different Types of M.2 Slots:
There are two main types of M.2 slots: SATA and PCIe. SATA-based M.2 slots are designed to support SSDs that use the SATA interface, while PCIe-based M.2 slots are designed to support SSDs that use the PCIe interface.
SATA-Based M.2 Slots:
SATA-based M.2 slots are designed to support SSDs that use the SATA III interface, which has a maximum theoretical speed of 6 Gbps (gigabits per second). These types of SSDs are typically less expensive than PCIe-based SSDs and are often used in budget builds.
One thing to keep in mind when using SATA-based M.2 slots is that they share bandwidth with other SATA ports on your motherboard. This means that if you have multiple SATA devices connected to your motherboard, using an SATA-based M.2 slot may result in reduced performance for those devices.
PCIe-Based M.2 Slots:
PCIe-based M.2 slots are designed to support SSDs that use the PCIe interface, which has a maximum theoretical speed of up to 32 Gbps. These types of SSDs are typically more expensive than SATA-based SSDs but offer significantly faster read and write speeds.
One advantage of PCIe-based M.2 slots is that they do not share bandwidth with other devices on your motherboard, which means you can use them without worrying about reduced performance for other devices.
There are also multiple PCIe versions available, including PCIe 3.0 and PCIe 4.0. PCIe 4.0 is the latest version and offers even faster data transfer rates than PCIe 3.
Conclusion:
In conclusion, there are two main types of M.2 slots are designed to support SSDs that use the SATA interface and are typically less expensive than PCIe-based SSDs. PCIe-based M.2 slots, on the other hand, are designed to support SSDs that use the PCIe interface and offer significantly faster read and write speeds.
When choosing an M.2 slot for your build, it’s important to consider your budget and your performance needs. If you’re on a tight budget, an SATA-based M.2 slot may be the best choice for you. But if you want the fastest possible read and write speeds, a PCIe-based M.2 slot is definitely worth considering.
Now that you know about the different types of M.2 slots available, you can make an informed decision when building or upgrading your computer!
