Are you also facing the same situation to replace your M.2 SSD, but don't want to reinstall the operating system? Don't worry. On this page, you will learn what an M.2 SSD, how to upgrade and clone M.2 SSD to a larger M.2 SSD, and what to do after cloning M.2 to M.2 in a complete guide. By inserting both SSDs into the slots, we shall start the whole cloning process with the SSD cloning software.

Part 1. Prepare M.2 SSD

Cloning a hard drive to an SSD can optimize the computer's performance without reinstalling Windows or losing data. Cloning M.2 to a larger M.2 SSD also works the same. Before you start, follow the steps here to prepare your new M.2 SSD disk ready:

Step 1. Check the Number of SSD Slots on Your PC

• Open the Laptop or Desktop computer case with a screwdriver.
• Then, check the number of SSD slots on your computer. 

Step 2. Buy a Right M.2 SSD

When you are ready to purchase a new M.2 SSD, remember three things:

• M.2 SSD must share the same length as the SSD slot in your PC.
• If your PC has one slot, buy an M.2 SSD and an M.2 SSD USB adapter. 
• The capacity of the new M.2 SSD should be twice or three times bigger than the old one. (500GB and 1TB are hot on Amazon.)

Step 3. Install the New M.2 SSD to the Laptop/PC

• If your PC has one SSD slot, connect the new M.2 SSD to the computer via an SSD USB adapter.
• If your laptop or desktop contains two SSD slots, install the SSD:

💻On a laptop: Open M.2 slot > Slide M.2 SSD inside the slot > Screw the SSD drive in > Finalize and cover.

🖥️On a desktop computer: Find the M.2 connector, labeled as "PCIe" > Insert M.2 SSD inside the slot > Secure the M.2 SSD with the mounting screw.

Step 4. Initialize New M.2 SSD

To guarantee a smooth M.2 to M.2 cloning process, you need to initialize the SSD first. 

• Open Disk Management, locate, and right-click the original M.2 SSD.
• Select "Properties" and check the partition style of your source SSD.
• Right-click the new M.2 disk and select "Initialize Disk".
• Set the partition style the same as the source disk (MBR or GPT) and click "OK" to confirm.

Now, you are good to move to Part 2, starting to clone M.2 to a larger M.2 disk on your own.

Part 2. How-to Tutorial: Clone M.2 SSD to a Larger M.2 SSD

#2. Tutorial: Upgrade & Clone M.2 SSD to Larger M.2

With EaseUS disk cloning software, follow the tutorial here to upgrade an M.2 SSD to a larger M.2 SSD with ease.

Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.
