Why Do You Need Hard Drive Mirroring Software?
Hard drive mirroring software is an essential tool for anyone looking to protect their operating system or data on a disk. It works by creating a replica, or "mirror" of your hard drive, ensuring that everything is duplicated at a time, e.g., operating system, installed programs, personal data, etc.
If your primary drive fails, the mirrored drive is ready to take over without losing any data. You can use it in different scenarios:
- Upgrade hard drive to larger or faster drive safely.
- Migrate OS to new SSD quickly.
- Clone failing hard drive for replacement.
- Duplicate hard drive for backup purposes.
- Transfer data from one computer to another

AOMEI Cloner is one of the best disk mirroring software that offers users different cloning methods for different needs and advanced features to make sure the cloning process goes smoothly.
3 Cloning Methods for Different Needs
| Disk Clone | creates an exact copy of the original drive, with which you can easily upgrade hard drive, replace old or failing drive, use it as a backup copy, etc. |
| System Clone | Clone OS only, including the operating system, recovery partition, apps, personal data, etc., to a new drive without reinstalling Windows, even smaller SSD. |
| Partition Clone | Backup specific partitions and data on them to keep them safe or for data migration. |
✅ Pro Tip: The previous two methods can clone a boot drive and make the cloned drive bootable. Which one should you use? What are the key differences? See disk clone vs system clone before making a decision.
Advanced Features to Clone a Drive Safely
|
Intelligent Clone (default) Clone only the used sectors of a drive, making it easier to clone large drive to smaller drive without data loss. |
Edit Partitions Automatically resize partitions of a larger disk during cloning. Optionally, adjust partition size manually and convert disk types, e.g., from MBR to GPT, or vice versa. |
|
SSD Alignment Make full use of 4k alignment to improve SSD disk performance and extend its lifespan. |
Create bootable USB drive, CD/DVD, or ISO file to access the Windows recovery environment and clone hard drive or SSD smoothly. |
How to Mirror HDD to SSD in 3 Easy Steps (Secure Boot)
Step 1. Connect the new SSD using an adapter and be sure it’s recognized. Then, open AOMEI Cloner after installing, and click Clone > Disk Clone.
Step 2. Choose the old HDD and new SSD, respectively.
Step 3. Check SSD Alignment to improve SSD disk performance and click Edit Partitions to convert and clone MBR to GPT (if necessary), or vice versa. At last, click Start Clone to mirror HDD to SSD.
- Notes:✎...
- The partitions will be automatically resized if the new SSD is larger. Optionally, you can click Edit Partitions to confirm this.
- The sector by sector clone mode will clone all sectors of a drive and takes longer.
After cloning, swap the two drives and set boot priority for new SSD in BIOS to let Windows boot from it. Click cloned SSD wont boot if you have any questions.
