What You Need to Do Before Installing M.2 SSD

M.2 SSD is lightweight storage that’s specifically designed for the PCI Express physical card layout and connectors. Since it has a smaller form factor and more flexible physical specification, M.2 SSDs attract a great many people.

However, most people are unclear about how to install M.2 SSD. In order to install an M.2 SSD successfully, here are some important things that you should pay attention to.

# 1. Check Your Motherboard

As you know, M.2 SSDs are commonly used in newer laptops. If you use M.2 SSD on an older computer, it may not be compatible with your motherboard. So, you need to make sure that your motherboard has an M.2 slot before installing M.2 SSD.

To check if you have a compatible M.2 slot, you can consult the manual of your motherboard. If you can’t find the motherboard manual, then you can follow the steps below:

Step 1. Find the motherboard name and model number of your motherboard.

  1. Usually, you can find the manufacturer name and model number near one of the four edges of the motherboard on the top side.
  2. Alternatively, you can find them through the Windows system information. Press the Win + R keys to open the Run dialog box, and then type msinfo32 in it and hit Enter. Then you can view the motherboard information under the System Summary

Step 2. Check if your motherboard has a compatible M.2 slot.

  1. Write down the motherboard information that you have found in the above.
  2. Use your Google to search for the motherboard manual.
  3. Carefully view the search results. Here you should know your motherboard information.

# 2. Choose a Right SSD

If you have ensured that your motherboard supports the M.2 SSD, now it’s time to choose a suitable SSD. To help you choose a suitable SSD for your laptop, we summarize some useful tips that you can refer to:

  • Purchase the right type of M.2 SSD. As you might know, M.2 SSD is mainly identified by the computer through the 2 main technology standards (PCIe and SATA). PCIe is faster than SATA. You need to check if your motherboard slots support PCIe or SATA M.2 SSD. A simple way is to check the notches on the connector. A SATA M.2 SSD has two notches, while a PCIe M.2 SSD has a single notch on the right side. Here it’s recommended that you choose PCIe M.2 SSD because of its faster speed.
  • Choose the right physical size. You need to see the physical size of the SSD that your motherboard slot supports. M.2 SSDs are often 22mm width, while their length varies from 30mm to 110mm. For this, you can find the length of your M.2 slot from the motherboard manual.
  • Determine the M.2 key. There are 3 types of M.2 keys including B, M, and B+ M key. The M.2 key can also be found from the motherboard manual.

According to the above information, you should know how to choose the right M.2 SSD.

# 3. Get all Necessary Tools

In addition to preparing a right M.2 SSD for your PC, it is also necessary to get all the necessary tools. To open the side panel of your computer, you need to prepare a small flat head screwdriver. Since static electricity can damage your computer memory, so make sure that the entire M.2 installation is performed in an anti-static environment. So, an optional antistatic wrist strap must be prepared.
