How Do I Clone My M.2 SSD to Another M.2

"I am running a 128GB SSD on my laptop. Now the disk is getting full with more and more data. So, I buy a 250GB M.2 SSD and want to use it to replace the existing 128 SSD. I don't want to reinstall the operating system as well as the installed programs, or manually migrate the files. Someone told me that I can do it by cloning the 128GB M.2 SSD to 250GB M.2 SSD, but I don't have a clue. Is there anyone who can help?"

Normally, people choose to upgrade a computer hard drive to SSD so as to optimize computer performance without reinstalling Windows nor losing data. Cloning M.2 to larger M.2 SSD also works the same, however, the process is a bit different.

Follow the guide here, you'll learn how to upgrade M.2 SSD, cloning M.2 to larger M.2 successfully on your laptop and desktop computers:

Part 1. Prepare M.2 SSD

In this part, we'll guide you to prepare everything ready for M.2 cloning. Now, follow the steps here to prepare both your PC and the new M.2 SSD:

Step 1. Check the Number of SSD Slot on PC

Open the Laptop or Desktop computer case with a screwdriver. Then check the number fo SSD Slop on your computer.

For one slot, you'll need to buy one M.2 SSD and one M.2 SSD USB adapter. For two slots, you just need to purchase a new M.2 SSD.

Step 2. Buy a Right M.2 SSD

M.2 SSD is defined as a gum shipped stick, studded with NAND modules and a controller chip. When you are ready to purchase a new M.2 SSD, remember three things:

Purchase a new M.2 SSD

  1. 1. M.2 SSD must share the same length of the SSD slot.
  2. 2. The higher capacity the more expensive the M.2 SSD will be.
  3. 3. Purchase an M.2 SSD USB adapter if your computer only has one stop.

It's suggested that the capacity of the new M.2 SSD should be twice or three times bigger than the old one will be fair enough.

Step 3. Install or Connect the New M.2 SSD to PC

If your computer only has one SSD stot, connect the new M.2 SSD to your 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, remember to initialize the SSD first. 

1. Open Disk Management, locate and right-click the new M.2 disk.

2. Select "Initialize Disk", set the partition style the same as the source disk (MBR or GPT)

3. Click "OK" to confirm.

Intialize M/2 SSD

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