How to Check If Your SSD is Running in M.2 or U.2 Mode

by

SSDs have become increasingly popular due to their faster read and write speeds, improved reliability, and lower power consumption. They are available in different form factors such as 2.5-inch, M.2, and U.2. The M.2 and U.2 interfaces offer faster data transfer rates and improved power efficiency compared to the traditional SATA interface. It is essential to ensure that your SSD is running in the correct mode to get the maximum performance out of it.

Understanding SSD Form Factors

Before we proceed with the methods to check the SSD mode, let’s first understand the two main SSD form factors – M.2 and U.2.

M.2

M.2 is a form factor for SSDs that is smaller than the traditional 2.5-inch drives. It is a small, rectangular card that can be attached to the motherboard or a dedicated M.2 slot. M.2 SSDs support different interfaces such as SATA, PCIe, and NVMe.

U.2

U.2 is a form factor that is similar to the traditional 2.5-inch drives. However, U.2 drives use the NVMe interface and offer faster data transfer rates and lower power consumption compared to the SATA interface.

Checking SSD Mode in Windows

There are several methods to check if your SSD is running in M.2 or U.2 mode in Windows.

Device Manager

  1. Press the Windows key + X and select Device Manager.
  2. Expand the Disk drives section.
  3. Right-click on your SSD and select Properties.
  4. Navigate to the Details tab and select Hardware Ids from the Property drop-down list.
  5. Look for the interface type in the Value section. If it is NVMe, the SSD is running in U.2 mode. If it is SATA, the SSD is running in M.2 mode.

Disk Management

  1. Press the Windows key + X and select Disk Management.
  2. Look for your SSD and right-click on it.
  3. Select Properties and navigate to the Hardware tab.
  4. Look for the interface type in the Model section. If it is NVMe, the SSD is running in U.2 mode. If it is SATA, the SSD is running in M.2 mode.

Checking SSD Mode in BIOS

You can also check the SSD mode in BIOS. The method may vary depending on the motherboard manufacturer and BIOS version.

BIOS Setup Utility

  1. Restart your computer and press the key to enter BIOS Setup Utility (usually F2 or Del).
  2. Navigate to the SATA Configuration or NVMe Configuration section.
  3. Look for your SSD and check the interface type. If it is NVMe, the SSD is running in U.2 mode. If it is SATA, the SSD is running in M.2 mode.

UEFI Firmware Settings

Alternatively, you can check the SSD mode in the UEFI Firmware Settings. Here’s how:

  1. Press the Windows key + I to open the Settings app.
  2. Click on Update & Security.
  3. Click on Recovery.
  4. Under Advanced startup, click on Restart now.
  5. Click on Troubleshoot.
  6. Click on Advanced options.
  7. Click on UEFI Firmware Settings.
  8. Click on Restart.
  9. Navigate to the SATA Configuration or NVMe Configuration section.
  10. Look for your SSD and check the interface type. If it is NVMe, the SSD is running in U.2 mode. If it is SATA, the SSD is running in M.2 mode.

Other Methods

Apart from the methods mentioned above, you can also check the SSD mode by referring to the manufacturer’s specifications or by using third-party software such as CrystalDiskInfo.

Conclusion

It is essential to ensure that your SSD is running in the correct mode to get the maximum performance out of it. We have discussed different methods to check if your SSD is running in M.2 or U.2 mode. By following these methods, you can determine the SSD mode and optimize your computer’s performance accordingly.

FAQs

  1. What is the difference between M.2 and U.2? M.2 is a smaller form factor for SSDs, while U.2 is similar to the traditional 2.5-inch drives. U.2 drives use the NVMe interface and offer faster data transfer rates and lower power consumption compared to the SATA interface.
  2. Can an M.2 SSD be used in a U.2 slot? No, an M.2 SSD cannot be used in a U.2 slot as they use different interfaces.
  3. Can a U.2 SSD be used in an M.2 slot? No, a U.2 SSD cannot be used in an M.2 slot as they use different interfaces.
  4. What is NVMe? NVMe stands for Non-Volatile Memory Express, which is a high-performance host controller interface designed for SSDs.
  5. Can checking the SSD mode harm my computer? No, checking the SSD mode does not harm your computer in any way. It is a simple diagnostic process that helps you optimize your computer’s performance.
