1. Prepare a New SSD, Set It Up in the PC Correctly

The first step is to ensure you have a suitable replacement SSD. This section will walk you through selecting, installing, and setting up your new SSD.

Select a new SSD:

When selecting a new SSD, ensure its storage capacity exceeds the amount of data currently stored on your existing drive. This will ensure you have sufficient space to transfer all your files.

Types of SSDs you can choose from:

• SATA SSD: Compatible and reliable for most PCs, but slower than newer models.
• NVMe SSD: Offers significantly faster performance via the PCIe interface.
• M.2 SSD: A compact form factor that supports SATA and NVMe interfaces.
• PCIe SSD: Offers even faster speeds than NVMe M.2 SSDs, usually found in high-end systems.

Popular SSD brands:

• Samsung
• Crucial
• Western Digital
• Intel

Install the new SSD

The next step, after purchasing your SSD, is to install it. The installation method depends on the type of connection your PC supports. You can typically install the SSD using a connection cable, an SSD slot, or an external SSD enclosure. For desktop users, it's important to consult the user manual, as component placements can vary. Also, check that the SSD is compatible with your motherboard.

Necessary tools for SSD installation:

• The screwdriver is set to unscrew.
• The SSD that you want to install. (We're installing an M.2 SSD).

Follow the steps:

Step 1. Disconnect your PC from the power sources and then open the case. Unscrew the side of your case.

Step 2. Locate M.2 slot. Maybe behind your GPU, as mine is on the Z490 Unify.

Step 3. If the motherboard has integrated heatsinks, remove one before installing an M.2 SSD. Unscrew it and set it aside temporarily.

Step 4. Locate your M.2 SSD slot, remove the screw, and insert the SSD diagonally.

Step 5. Screw it back in. The M.2 drive has a small semicircular hole, so you'll see where the screw goes.

Step 6. Once physical installation is done, reassemble hardware parts. Follow the same steps in reverse order.

Set up SSD

Now, you need to initialize your SSD to match the partition style of your current drive. The partition style of your SSD should align with the source HDD/SSD. For instance, if your old HDD uses MBR (Master Boot Record), your new SSD should also be set to MBR.

You can check and adjust this configuration using your PC's Disk Management settings. Follow the steps to set up and initialize the new SSD:

Step 1. Right-click the Start menu and select Disk Management.

Step 2. Ensure the SSD is shown as Online. If it appears as Offline, right-click the SSD and select Online.

Step 3. Right-click the new SSD and select Initialize Disk.

Step 4. In the Initialize Disk window, select the SSD and choose the appropriate partition style (MBR or GPT) based on your current drive.

Step 5. Click OK to begin the initialization process. Afterward, right-click the SSD and choose New Simple Volume.

Step 6. Follow the instructions in the New Simple Volume Wizard to allocate space.

Note: If the target SSD is already installed on your PC, make sure to back up your data and clean the drive before proceeding with the setup to avoid any data conflicts.

2. Replace SSD in PC/Laptop: Clone OS, Data, or Entire Disk to New SSD

To change the SSD in your PC or laptop without losing data, you'll need reliable disk cloning software like EaseUS Partition Master. This disk management tool makes SSD replacements, cloning your OS, transferring files, or upgrading to a larger SSD easy. EaseUS Partition Master offers all the essential features you need. You can also perform additional tasks, like converting MBR to GPT for Windows 11, resizing partitions, and more.

Key Features of EaseUS Partition Master:

• Clone the Operating System: Transfer Windows without reinstalling.

Step 2. Select the target disk.

• Choose the wanted HDD/SSD as your destination and click "Next" to continue.
• Read Warning message and confirm "Yes" button.

Step 3. View the disk layout and edit the target disk partition size. 

Then click "Continue" when the program warns it will wipe out all data on the target disk. (If you have valuable data on the target disk, back up it in advance.)

You can select "Autofit the disk", "Clone as the source" or "Edit disk layout" to customize your disk layout. (Select the last one if you want to leave more space for C drive.)

Step 4. Click "Start" to start the disk cloning process.

3. Configure the New SSD as the Boot Drive If You Replaced an OS SSD

If you're simply swapping out a data SSD or HDD with a new SSD, feel free to skip this section and move to the bonus tip. However, if your purpose is to replace your old OS disk and migrate the operating system to the new SSD, you should configure the new SSD as the boot drive. This step will be required after migrating the OS to a new SSD.

Follow the steps:

Step 1. Restart your PC and press F2/F12/Del keys to enter BIOS.

Step 2. Once inside the BIOS settings, navigate to the Boot or Boot Order section using the arrow keys on your keyboard.

Step 3. In the Boot Order section, you'll see a list of available drives. Select your new SSD and move it to the top of the list to set it as a primary boot device.

Step 4. Save the changes, exit BIOS, and restart the PC. Wait and let the PC boot up.

4. Bonus Tips for Changing SSD in PC, You Can't-Miss

It's important to optimize your new SSD for the best performance and properly reset your old SSD or HDD for future use. Here are some essential tips and best practices:

To Optimize Your New SSD:

• Enable TRIM: TRIM helps your SSD manage unused space efficiently, improving performance and longevity.
• 4K Align SSD: Proper 4K alignment ensures the SSD reads and writes data efficiently, reducing wear and boosting speed.
• Back-up SSD Data: Regularly back up important files to ensure data safety in case of failure.
• Set the Correct File System: Ensure your SSD partitions are formatted with the proper file system (e.g., NTFS for Windows or APFS for macOS).
• Check for Firmware Updates: Updated firmware can enhance performance and security.
• Disable Disk Defragmentation: SSDs don't need defragmentation, so disable this feature to avoid unnecessary wear.

To Reset Your Old SSD or HDD:

• Format Old Data SSD or HDD: Formatting it will clear out existing data and prepare it for new uses.
• Wipe the Drive Before Giving It Away: If you want to sell your old drive, wipe the entire drive to protect your privacy.
