Want to move all files from one SSD to another without losing data or reinstalling Windows? This guide covers two easy and secure methods to transfer everything, whether you're upgrading your SSD or migrating your system.
"Recently, I got a new computer but immediately filled up the SSD with files and programs. Now I'm low on disk space. I intend to replace the current SSD with a larger one. But I want to keep the files, games and the OS on the SSD. I'm wondering how to transfer everything from one SSD to another."
YES, you can transfer data from one SSD to another without reinstalling operating system and applications. Here are 2 common ways to easily move files from one SSD to another, suitable for beginners and advanced users.
Transferring data from one SSD to another can be achieved using methods that best suit your needs. When it comes to a full system migration—including moving Windows—a more robust approach is required.
Disk cloning creates an exact replica of your current SSD, eliminating the need to reinstall Windows or reformat your drive. This seamless process copies every aspect of your system so that your new SSD is ready to use immediately.
Alternatively, you can create a system backup and restore it to the new SSD. Although this method may involve extra steps, it’s ideal if you can’t connect both SSDs at the same time (i.e. transfer data from one SSD to another with only one slot) or need to migrate data across different hardware platforms.
Both approaches are supported by AOMEI Backupper Professional—a trusted migration tool designed to handle all types of HDD and SSD transfers recognized by Windows. This software not only transfers your files, applications, and operating system without reinstallation, but it also offers advanced features such as:
✅ Transfer Everything | Complete data transfer for programs, games, and the OS, no reinstalling |
✅ Intelligent Cloning | Copy only used sectors to target drive, best for migrating to a smaller SSD |
✅ SSD Alignment | 1-click to optimize performance and prolong lifespan |
✅ MBR/GPT Cloning | Clone SSDs between MBR and GPT partition style |
✅ Flexible Cloning | Clone only system drives to another SSD with System Clone feature |
✅ Securely Boot | Hassle-free system startup after cloning |
Download this SSD cloning software and discover how easy SSD migration can be. If you are a Server user, try the Server edition instead.
In this part, you can learn how to transfer SSD to SSD easily and securely in 4 steps.
Before moving files and OS to another SSD, you need to do some preparations:
Install the target SSD to your computer alongside the old SSD. If there's no extra port, you may need a SATA-USB cable or SSD enclosure to connect it.
Install and launch AOMEI Backupper.
The cloning will overwrite everything on the target SSD. Be sure to make a backup if there's any important data.
In the main interface, navigate to "Clone" tab and select "Disk Clone". It will move everything from one SSD to another.
✍Tip: The trial version allows you to preview the cloning process but does not execute the operation. To clone your system disk, please upgrade to unlock full feature.
Select the original SSD that you want to clone as the source disk, and then click on "Next".
Choose the new SSD that you want move files to as the destination disk, and then click on "Next".
Tick “SSD Alignment” to optmize SSD performance. Then, click "Start Clone" to begin cloning one SSD to another.
📕Tips on disk space management and disk partition styles:
You can use the "Edit Partitions" feature to resize partitions with different options and convert the disk type.
📕 Choose the right cloning mode
When transferring data, this software uses Intelligent Sector Mode by default. This means it copies only the used sectors, automatically skipping unused sectors and logically bad sectors to optimize speed and storage efficiency.
If your target drive has less capacity than the source drive, keeping this default mode ensures a smooth transfer without exceeding available space.
However, if your target drive is equal to or larger than the source drive, you have the option to enable Sector-by-Sector Cloning. This method copies all sectors, including unused ones, ensuring an exact 1:1 clone. It is particularly useful when migrating a hidden recovery partition, as it preserves its functionality on the new drive.
If you want to transfer data from one SSD to new SSD without losing data completely for free, you can also turn to the powerful backup and restore features that are included in AOMEI Backupper Standard (the free edition).
As a free backup and restore tool, it can help you transfer all data including OS from SSD to SSD by backing up the old disk and restoring it on new drive. Follow the steps below to create and restore the backup image of your SSD.
✍Tip: If you plan to install the cloned SSD on a new computer with different hardware, please use the Universal Restore feature available in the advanced edition. This ensures system compatibility by adapting the cloned OS to the new hardware environment.
Connect the target SSD to your computer and ensure it is properly detected. Then, install and launch AOMEI Backupper.
📌 If you cannot connect the SSD directly, create a bootable disk to start your computer in a WinPE (Windows Preinstallation Environment). After that, replace the old SSD with the new one and perform a system recovery using the bootable drive.
Before proceeding, create a complete image of your source SSD using the Disk Backup or System Backup feature. If you only need to back up certain files or partitions, choose File Backup or Partition Backup accordingly.
💡 For maximum data security, it’s recommended to save the backup image on an external USB drive or a network location.
In the "Home" tab, select disk backup task and click "Restore" option.
You can choose to restore entire disk or a partition in the disk, and click "Next".
Select connected SSD as the destination disk. Confirm the operations and click "Start Restore".
📢Note: This method applies to encrypted SSD data migration and complex RAIDs transferring as well.
RAID (Redundant Array of Independent Disks) improves performance or data redundancy, but migrating it requires extra care.
Break the RAID array temporarily in BIOS/UEFI or RAID controller settings.
Clone each SSD individually using tools like AOMEI Backupper.
Reassemble the RAID with the new SSDs using the same controller.
Verify data integrity before deleting the old array.
⚠️ Warning:
RAID 5/6 requires rebuilding parity, which is riskier—consult your RAID controller manual.
Some hardware RAID setups may not support direct cloning—check manufacturer guidelines.
Create a full backup of the RAID volume.
Replace the SSDs and reconfigure RAID in BIOS.
Restore the backup to the new array.
✍Tip: If using software RAID (Windows Storage Spaces), use its built-in "Remove Disk" and "Add Disk" functions to migrate safely.
Encrypted SSDs cannot be cloned directly without decryption. You can transfer files from BitLocker SSDs in Windows with these methods:
✅ Option A: Decrypt → Clone → Re-encrypt
Suspend BitLocker (Control Panel → BitLocker → "Suspend Protection").
Clone the SSD using AOMEI Backupper.
Re-enable BitLocker on the new SSD.
✅ Option B: Backup & Restore (No Decryption Needed)
Create a BitLocker recovery key (if you don’t have one).
Back up the drive using AOMEI Backupper (supports encrypted backups).
Restore to the new SSD and enter the recovery key when prompted.
⚠️ Critical Note:
Never clone an encrypted SSD while locked—this can corrupt data or make it unrecoverable.
TPM-bound encryption (like BitLocker with TPM 2.0) may require reactivation on the new SSD.
Important Takeaways:
✔ RAID Migration: Break the array before cloning, or use backup/restore for safety.
✔ Encrypted SSDs: Always decrypt first (or use backup tools that support encryption backup).
✔ Verify Data: After migration, check file integrity before deleting the original drive.
If you don’t want to install third-party software, Windows provides built-in tools to help you move files between SSDs. Here are two simple methods:
Connect the new SSD to your PC.
Open File Explorer and locate your current SSD.
Select the files/folders you want to transfer, right-click, and choose Copy.
Navigate to the new SSD, right-click, and select Paste.
Repeat until all necessary files are transferred.
Open Control Panel > Backup and Restore (Windows 7).
Click Create a system image and choose the SSD as the destination.
Follow the on-screen instructions to back up your data.
After installing the new SSD, restore the backup to complete the transfer.
While these methods work for basic file transfers, they may not be ideal for migrating system files or applications. If you need a full disk transfer, using an SSD cloning tool is recommended.
Many users wonder how to move files and OS from one SSD to another in Windows 11/10, one of the easiest way is using professional program such as AOMEI Backupper. It helps you transfer data from SSD to SSD effortlessly, whether you want to clone drive to smaller SSD or larger SSD.
In addition, AOMEI Backupper applies to clone all kinds of SSDs, such as clone HDD to Samsung SSD, clone HDD to Seagate SSHD, clone NVMe to another NVMe, etc.
