How to Clone RAID Disk (Hardware & Software)
RAID (Redundant Array of Independent Disks) has become very popular in recent times, thanks to its unique data storage and protection features. There are, of course, many types of RAID setups for data storage, and each setup offers distinctive benefits – and requires a specific setup procedure.
Most RAID levels can be set up with at least two (2) hard drives, but some RAID levels require a minimum of three (3) or four (4) disks to set up. This article explains all you should know about RAID setups and how you can clone RAID drives. Cloning RAID drives could be a way of backing up the data content on the drive(s) for data loss scenarios.
What is a RAID Array?
In simple understanding, a RAID array is the systematic arrangement of two or more hard drives to achieve a RAID level. What distinguishes between RAID levels and arrays is how the member drives are set up using a RAID controller (could be software or hardware controller); it is the RAID controller that determines the actual RAID level or array you’re building.
Common RAID levels are RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 01, RAID 50, and other configurations. A RAID array could offer striping, mirroring, parity distribution, or any two of these data storage techniques. While some RAID levels may offer high data redundancy and resilience in critical hard drive conditions, they are still not a full substitute for data backups.
Setting up RAID can significantly improve read and write performance, as well as foster business continuity in case of drive failure. Most RAID levels will continue to function even when there’s a failed drive in the array and will automatically rebuild when you replace the failed drive with a new one.
There are complexities among RAID levels, but the fact remains that RAID is better than single-storage, especially in data centers or business environments where drive failure could affect a whole lot if there are redundancy solutions set up for such scenarios.
How to clone RAID?
Some RAID arrays like RAID 1 do not offer “more space,” regardless of how many drives you use in the array – you will only get the space of the “smallest” drive as your total space. Cloning a RAID array is possible; you can either clone the individual drives or clone RAID. Well, to clone the entire RAID to a new single drive, the new drive must have enough space relative to the total storage offered by the RAID array.
For example, if the total storage offered by a RAID is 2TB, you need a single 2TB drive to clone RAID. There are several reasons why one may want to clone RAID storage, and this can be linked to data backup considerations. Also, RAID levels can be complicated in how they read and process data, so at some point, you may just want to switch to a single-drive storage. But regardless of what your reasons are, cloning a RAID storage is possible.
Why Should You Clone RAID to a Single Drive?
- RAID rebuilding
- RAID array decommissioning
- System migration
- Data backup
Different data environments call for specific data storage needs. Moreover, RAID is not foolproof for data loss – and is more difficult to manage compared to single-drive storage. NAS systems and DAS setups all use RAID technologies for data storage – allowing you to access your data from different systems simultaneously without sacrificing data transfer speed and upholding redundancy.
But then, most RAID levels can’t reconstruct data when one or two drives fail in the array, which makes regular backups the only reliable foolproof solution to data loss cases. Backing up and restoring RAID data can be a bit challenging, but much easier with a single drive. You can clone RAID to a single drive, so when a drive fails in the array and the RAID won’t rebuild automatically, you can retrieve the lost files/data from the single drive.
Also, if you’re about to run system migration, cloning your RAID to a single drive to run the migration from the single drive would be a lot easier. But, cloning RAID to a single drive to subsequently use the single drive as your preferred storage is quite risky, if the single drive fails, all your data will be instantly inaccessible and lost, probably.
How to Clone RAID Array to Single Drive/SSD in Windows?
First things first, you need a professional software tool to clone RAID. Most RAID cloning software programs are premium apps, you have to pay to use them.
- Step One: Download and install RAID cloning software like Wondershare UBackit, and launch the program.
- Step Two: From the program’s main screen, click on the “Clone” tab and select the RAID drives/volumes as the “Source” drive(s). Click “Next.”
- Step Three: Select the single drive storage device as your “Destination Disk,” and click next. In the pop-up prompt, confirm the cloning process and wait for the cloning process to run completely. Your RAID data will now be available on the selected single-drive storage.
Note: Before you can clone RAID drive with this program, the clone destination disk must offer sufficient space equivalent to the total data size from your select source “RAID drives.” The cloning process may take a long time depending on the data size and disk speed.
Clone Hardware RAID
Hardware RAID is when you use an external RAID controller hardware for your RAID setup. This type of RAID setup is proven to offer faster performance and flexibility than software RAID, but at a cost – hardware RAID is more expensive to set up because of the additional hardware (the controller). Cloning hardware RAID is no different from cloning any other type of RAID setup and hereunder are the steps.
- Step One: Download and install MiniTool Partition Wizard and launch the program on your Windows PC
- Step Two: On the program’s main page, right-click on the RAID drive and select “Copy.”
- Step Three: Choose the single drive to where you want to save the RAID data. (Note: any previously saved data on the single drive will be overwritten).
- Step Four: Confirm the operation following the on-screen prompts and wait for the cloning to be complete.
Clone Software RAID
Most home users prefer the software RAID because it is more affordable and also flexible to a great extent. While software RAID might not offer the best performance compared to hardware RAID, it does offer reasonable performance speeds – based off the host PC’s specs and capabilities. Cloning software RAID is the same as cloning hardware RAID, the only difference, in software RAID, you’re choosing “volumes” and not drives per se.
- Step One: Download and install MiniTool Partition Wizard and launch the program on your Windows PC
- Step Two: On the program’s main page, right-click on the stripped or mirrored RAID volume and select “Copy Volume.”
- Step Three: Choose the single drive to where you want to save the RAID data to. (Note: you can’t copy the RAID volume to another partition on the same disk).
- Step Four: Set partition size and other configurations and confirm the cloning; you should leave everything at the default values and settings if you’re unsure what they imply.

FAQ
Can I Clone a RAID 1 Drive?
Yes, you can clone a RAID 1 drive. RAID 1 is a mirrored set, meaning data is duplicated across two or more disks. Cloning a RAID 1 drive involves creating an exact copy of one of these mirrored drives. This process is typically straightforward since RAID 1's redundancy ensures that each disk contains a complete copy of all data. You can use disk cloning software that supports RAID configurations to perform this task. It's important to ensure the destination drive has equal or larger capacity than the source drive in the RAID 1 array.
Can I Clone a RAID 0 Drive?
Cloning a RAID 0 drive is more complex than cloning a RAID 1 drive. RAID 0 splits data across multiple disks (striping) without redundancy, aiming to increase performance. To clone a RAID 0 array, you must clone all drives in the array simultaneously because the data is distributed across each disk. This requires cloning software capable of recognizing and handling RAID 0 configurations. The process involves creating an exact copy of the striped set of disks onto another set of disks or a single large disk. Ensure the destination storage can accommodate the total data from the RAID 0 array.
How to Clone RAID 1 to a Single Drive

Can you move a RAID from one computer to another?
Step 1: Verify RAID Controller Compatibility
- Hardware RAID: If your RAID array is managed by a hardware RAID controller, ensure the new computer has a compatible controller. Ideally, use the same model or one from the same manufacturer that supports your RAID configuration.
- Software RAID: For software RAID configurations (managed by the operating system), ensure the new system supports the same software RAID setup.
Step 2: Backup Your Data
- Before moving the RAID array, back up all data to another location. This precaution protects against data loss due to unforeseen issues during the transfer process.
Step 3: Document RAID Configuration
- Note down the RAID type (e.g., RAID 0, RAID 1, RAID 5, RAID 10), stripe size, disk order, and any other configuration details. This information is crucial for reconfiguring the RAID array on the new system.
Step 4: Prepare the New Computer
- Ensure the new computer can physically accommodate the RAID disks (enough drive bays, compatible interfaces).
- Install any necessary RAID controller drivers or software on the new system before installing the RAID disks.
Step 5: Shut Down and Disconnect
- Safely shut down the old computer and disconnect the RAID disks, noting their order and configuration.
Step 6: Install the RAID Disks in the New Computer
- Install the RAID disks in the new computer, maintaining their original order. If using a hardware RAID controller, install the controller in the new system (if not already compatible or integrated).
Step 7: Reconfigure RAID Setup
- Hardware RAID: Access the RAID controller’s BIOS or management software to reconfigure the RAID array as it was on the old system, using the documentation from Step 3.
- Software RAID: Boot the new system and use the operating system’s RAID management tools to reconfigure the RAID setup.
Step 8: Verify and Boot
- Once the RAID array is reconfigured, boot the new system and verify that the RAID array is recognized and functioning correctly. Check data integrity and accessibility.
Step 9: Perform a Final Data Backup
- After ensuring the RAID array is operating as expected in the new environment, perform another data backup to safeguard against future data loss.
