Best M.2 Cloning Software to Clone M.2 SSD [Full Guide]

Why clone M.2 SSD to another M.2 SSD?

An M.2 SSD (Solid State Drive) is a high-performance storage device that utilizes the M.2 interface, which is faster and more compact than traditional SATA-based SSDs. M.2 SSDs are commonly used in modern laptops, desktops, and even gaming consoles due to their speed, reliability, and slim design.

You may want to clone M.2 SSD to another M.2 SSD for the following reasons:

• Upgrade to a Larger SSD: If your current SSD is running out of storage space, cloning it to a larger M.2 SSD allows you to expand your storage capacity without reinstalling your operating system and applications.
• Improved Performance: Newer M.2 SSD models often come with better performance specifications, such as faster read/write speeds. Cloning to a newer, more advanced SSD can boost system performance.

How to clone M.2 SSD to M.2 SSD in Windows 11/10/8/7

This part will describe how to clone M.2 SSD to larger M.2 SSD with the best M.2 SSD cloner. Please check the detailed guide below.

#1. Preparations before cloning M.2 SSD

✅ Choose a compatible M.2 SSD

Check your computer's supported interface type to determine whether you should buy a SATA M.2 SSD or an NVMe M.2 SSD.

Also, choose a capacity larger than the amount of data stored on your current M.2 SSD. Keep in mind that SSDs with higher capacities tend to have better performance and longer lifespans.

✅ Check M.2 slot number

Check how many M.2 slots your computer has. If your computer only has one, you may need a USB to M.2 SSD adapter or a PCIe M.2 expansion card.

✅ Connect the new M.2 SSD

• For the computer with two slots, directly slide your M.2 SSD into the slot and screw it up tightly.
• For the computer with one slot, connect your M.2 SSD with an adapter or enclosure.

✅ Get the new M.2 SSD ready

• If it’s a brand new SSD, you may initialize it in Disk Management. Open Disk Management, locate and right-click the new M.2 SSD and select Initialize Disk.
• If the SSD is already initialized and has some data on it, backup the data you still need before cloning. The destination disk will be overwritten during the cloning process.

#2. Steps to clone M.2 SSD to larger M.2 SSD

Now, see below and learn the detailed steps to clone M.2 SSD to larger M.2 SSD with M.2 SSD clone software in Windows 11/10/8/7.

Step 1. Open AOMEI Cloner to enter its main interface after the installation. Select Clone > Disk Clone in turn.

Step 2. Choose the smaller M.2 SSD drive as the source disk to clone, and go to Next.

Step 3. Select the larger M.2 SSD as the destination disk, and go Next.

Step 4. In the Operation Summary page, click Edit Partitions and choose Add unused space to all partitions or Manually adjust partition size to resize partitions and avoid unallocated space. You can also convert disk types (MBR and GPT) with it.

Step 5. Tick SSD Alignment to optimize the performance for M.2 SSD disk and click Start Clone to perform M.2 clone safely.

#3. Boot from the cloned M.2 SSD

After cloning M.2 SSD to M.2 SSD, you may need to boot from the cloned M.2 SSD. Pick one way to boot from the new M.2 SSD according to your situation.

👉 Situation 1: The new M.2 SSD is connected via an adapter

1. Open your computer case. Remove the mounting screw from the M.2 slot and take out the old M.2 SSD.

2. Plug the new M.2 SSD into the slot and pay attention to the notch.

3. Secure the M.2 SSD with the mounting screw removed earlier.

4. Reassemble your computer and restart. It should boot as normal.

👉 Situation 2: The new M.2 SSD is installed in an extra slot

1. Restart your computer and press the specified key in the initial screen (e.g.: F2, ESC) to access BIOS.

2. Go to the Boot Menu. At the boot priority section, set the new M.2 SSD as the first boot drive.

3. Press F10 to save all the changes and restart the computer.
