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
Part 2. How-to Tutorial: Clone M.2 SSD to a Larger M.2 SSD
Part 3. Boot PC from Cloned M.2 SSD and Manage Old M.2 SSD

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.

Frequently Asked Questions

Why choose EaseUS Todo Backup?

"The easiest way to protect your data and system files."techradar

What is the difference between Clone and Backup? In what cases should I use Clone?

Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy. Backup will generate a .PBD image file containing the selected files or system that can be restored from the .PBD image if needed.

What is the difference between System Backup and Disk Backup?

System Backup will auto-select the system boot related partition(s) as the backup source to make sure the system image can be restored properly. Disk/Partition Backup will allow you to manually select a whole disk or speficy a certain partition as the backup source. You will get the same backup result as System Backup if you manually select the system and boot partitions with the Disk/Partition Backup option.

As a computer newbie, what features should I use to protect my computer?

You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.

What kind of storage service should I use to save my backup images?

EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD. It is suggested to save the images to the internal/external/network drives to save time as those kinds of disks have a better read-write speed. It is suggested NOT to save the image on the source disk, because once the disk is damaged, all the files on the disk will become unavailable and you will be unable to restore the image.

As a company network administrator, what features should I use to protect our internal computers?

It is recommended that you use the SQL Backup feature to back up your company's SQL server and Exchange Backup feature to back up the Exchange server. In addition, you can execute System Backup to back up the system and boot partitions on every computer and set a plan to execute the backup once a day or twice a week to ensure that the computer can be restored timely when it has boot issues. File Backup feature can be used to back up important user data. If there are a large quantity of computers, you can purchase EaseUS Backup Center to manage the backups on the client computers centrally.
