Note: If you've already bought the new M.2 SSD, jump to Step 3 in Part 1 to start the M.2 to M.2 cloning process. 

Part 1. Prepare M.2 SSD

Cloning a computer hard drive to SSD can optimize the computer performance without reinstalling Windows nor 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 Slot 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:

Purchase a new M.2 SSD

  • 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 Laptop/PC

  • If your PC has one SSD stot, 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.
