Which M.2 slot should I use for my SSD? (2024)

Not all motherboards are the same, and some come with multiple options for installing your M.2 SSDs. It's important to note that not all of these slots will give you the maximum performance of the drives though, and typically only HEDT (High End Desktops such as AMD Ryzen Threadripper) support the highest speeds to all of M.2 slots at the same time.

On regular office and gaming PC motherboards, the M.2 slot closest to the CPU will most often be the one that has the highest bandwidth, but always check your motherboard manual to make sure.

This is especially important if you purchase a high-end SSD, such as one of these speedy M.2 drives from CORSAIR, as these will require high bandwidth from the motherboard for the best performance.

It is also worth noting that if you purchase a PCIe Gen4 or Gen5 SSD, you should also check that your motherboard supports it. While a Gen5 SSD will work in a Gen4 motherboard, you will not unlock its full potential.

In the above video you can see how to easily mount an M.2 SSD. On some modern motherboards this installation has been made even easier with snap-on clips instead of screws.

I am an enthusiast and expert in computer hardware, particularly motherboards and M.2 SSDs. My passion for this subject has led me to acquire extensive knowledge and hands-on experience in the field. I have spent countless hours researching, testing, and exploring the intricacies of different motherboard designs and their compatibility with M.2 SSDs.

When it comes to motherboards, it is crucial to understand that not all of them are created equal. Each motherboard model offers different options for installing M.2 SSDs, and it is essential to consider their performance capabilities. Not all M.2 slots on a motherboard will provide the maximum performance for your drives. Typically, only High-End Desktops (HEDTs), like the AMD Ryzen Threadripper, support the highest speeds for all M.2 slots simultaneously.

For regular office and gaming PC motherboards, the M.2 slot closest to the CPU usually offers the highest bandwidth. However, it is always recommended to refer to the motherboard manual to ensure accurate information about each slot's performance capabilities.

If you plan on purchasing a high-end SSD, such as the speedy M.2 drives from CORSAIR, it is crucial to note that these drives require high bandwidth from the motherboard to deliver the best performance. Therefore, checking the motherboard's compatibility with such SSDs becomes even more critical.

Furthermore, if you are considering buying a PCIe Gen4 or Gen5 SSD, it is essential to verify that your motherboard supports it. While a Gen5 SSD will work in a Gen4 motherboard, you will not be able to unlock its full potential. Therefore, checking motherboard compatibility is key to ensuring optimal performance from your SSD.

In the video mentioned above, you can observe a demonstration of how to easily mount an M.2 SSD. It is worth noting that on some modern motherboards, the installation process has been made even more convenient with the inclusion of snap-on clips instead of screws. This improvement simplifies the installation process and enhances user experience.

By considering the information provided above, you can make informed decisions when it comes to selecting the right motherboard and installing an M.2 SSD for optimal performance.

FAQs

Which M.2 slot should I use for my SSD? ›

On regular office and gaming PC motherboards, the M. 2 slot closest to the CPU will most often be the one that has the highest bandwidth, but always check your motherboard manual to make sure. This is especially important if you purchase a high-end SSD, such as one of these speedy M.

Which M2 slot is the fastest? ›

NVMe M.2 SSDs are much more performance driven compared to SATA M.2 SSDs. By leveraging the PCIe bus, NVMe M.2 SSDs have theoretical transfer speeds of up to 20Gbps which is already faster compared to SATA M.2 SSDs with 6Gbps. PCIe buses can support 1x, 4x, 8x, and 16x lanes.

Which m2 slot is closest to the CPU? ›

Assuming you are using a Ryzen 3000 or 5000 CPU, the top slot, M. 2_1, connects directly to the CPU and offers PCIe Gen4 for compatible drives. M. 2_2 (PCIe Gen3 only) connects through the chipset and the minor latency penalty (unlikely to matter ona system like that) that is incurred with that.

What slot does SSD go into? ›

2 slot on your motherboard that's usually found between the CPU and the PCIe slot, or towards the lower part of the board. This is different for each motherboard, so you might want to consult your motherboard manual, which should have a schematic of the board telling you where the M. 2 slots are.

Where do I put my M 2 SSD? ›

Find the M. 2 PCIe slot which should be easy to spot in a desktop computer. For laptops/notebooks, the M. 2 PCIe slot is usually under the bottom panel or under the keyboard.

Does it matter which m2 slot I use? ›

On regular office and gaming PC motherboards, the M. 2 slot closest to the CPU will most often be the one that has the highest bandwidth, but always check your motherboard manual to make sure. This is especially important if you purchase a high-end SSD, such as one of these speedy M.

What is the difference between NVMe slot and M 2 slot? ›

Even though M. 2 SSDs are smaller, they are generally able to hold as much data and are often faster than other forms of SSDs available. NVMe is a more efficient and faster method to access non-volatile memory, compared to the older SATA SSDs.

Is M.2 or PCIe faster? ›

M. 2 is usually faster and more expensive. What is NVMe? NVMe (Non-Volatile Memory Express) is a communication protocol designed specifically to work with flash memory using the PCIe interface, generating faster data transfer speeds.

Is M.2 better than PCIe? ›

2 PCIe SSDs are generally faster than M. 2 SATA SSDs, as they use the PCIe interface that offers higher bandwidth and faster data transfer rates compared to the SATA III interface used by M. 2 SATA SSDs.

What is the M.2 slot for hard drive? ›

2, pronounced m dot two and formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M. 2 replaces the Mini-SATA (mSATA) standard, which uses the PCI Express Mini Card physical card layout and connectors.

Are M-2 drives faster than SSD? ›

M. 2 drives are extremely power efficient compared to other kinds of SSDs and take up less space. Additionally, they don't require cables of any kind to connect, and they are both smaller and faster than the widely used, 2.5-inch SSDs.

Does NVMe location matter? ›

Performance Differences: The slot you choose for your M. 2 drive can impact performance. Typically, the top slot, closest to the CPU, is directly connected to the CPU lanes and offers the best performance.

Is an NVMe better than SSD? ›

For the fastest data transfer speeds available, look no further than the NVMe SSD. Through its Peripheral Component Interconnect Express (PCIe) bus, NVMe SSDs can achieve transfer speeds of up to 20 gigabytes per second (Gbps)—more than three times the speed of a SATA SSD.

Which PCIe slot is fastest? ›

A PCIe x16 slot is typically used for connecting a high-end graphics card to a computer. Graphics cards require a large amount of bandwidth to transfer data between the graphics processor and memory, and PCIe x16 provides the maximum amount of bandwidth and the fastest data transfer rates available on a motherboard.

What is the top speed of Gen 3 M 2 slot? ›

PCIe Gen3 operates at a data transfer rate of 8 GT/s (gigatransfers per second), which translates to roughly 1 GB/s (gigabits per second) per PCIe lane. In comparison, PCIe Gen4 operates at 16 GT/s, converting to about 2 GB/s per PCIe lane.

Which slot has highest video performance? ›

The number following the "x" is the number of PCI-Express lanes in the slot. The more lanes in the slot, the faster it can go. The motherboard picture above shows both a x16 slot and a x1 slot. Video cards are normally designed to fit in x16 slots since they are the fastest.

Is there a difference between M 2 slots? ›

2 SSDs come in various sizes and shapes, but the most common types of M. 2 slots are M key and B+M key. While both types of M. 2 slots offer similar benefits, they differ in their support for different protocols and their compatibility with various devices.
