This is a RAID user's question. Generally, this is a common request as the RAID users. How to solve it? Clone RAID disk is a good way, by which small RAID disk can be upgraded or migrated data to a larger one and all operating system and applications are fully functional. This is an easy and convenient method. In order to understand RAID clone, let's learn some knowledge of RAID.
RAID, short for Redundant Array of Independent (or Inexpensive) Disks, a category of disk drives that employ two or more drives in combination for fault tolerance and performance improvement. RAID disk drives are used frequently on servers but aren't generally necessary for personal computers. RAID allows you to store the same data redundantly (in multiple paces) in a balanced way to improve overall performance which offers superior read/write performance, storage capacity and reliability over older storage solutions. There are different RAID levels and RAID 0, RAID 1, RAID 5 is the most common used.

Before cloning:
- If your computer has only one slot, connect the target disk to your machine via a USB-to-SATA/NVMe adapter.
- If your computer has an extra slot, install the target disk into the empty slot properly, and make sure it is compatible.
Step 1. Launch EaseUS Disk Copy and choose Disk Mode.
Install EaseUS Disk Copy cloning software on your Windows computer, then launch it and select Disk Mode from the left panel.
Step 2. Select the source drive.
Select the drive you want to copy, then click Select.
Step 3. Choose the target disk.
Choose the disk that you want to clone data to, and click Select. Note that the used space of the source disk should be less than the target disk capacity.
*At this step, you can also click the option "Save as an image file" to store your disk as a compressed image file, which can be restored without any data loss.
Step 4. Adjust disk layout.
Specify the target disk layout as your preference. You can choose among:
- Autofit the disk: makes some changes by default on the destination disk layout so that it can work at its best.
- Copy as the source: create a 1-to-1 copy of your source disk; the layout is the same as the source disk.
- Edit disk layout: allows you to manually resize/move the partition layout on this destination disk.
*If the target disk is an SSD, the option "Auto-alignment to 4K" will be checked automatically to optimize the performance of your SSD.
Step 5. Start cloning.
Click Proceed, and a message will appear, warning you that data will be lost. Confirm the message by clicking Continue.
Now, it will start executing the cloning task.
*The time it takes to clone a hard drive depends on how much data is on the source disk, and it will also be affected by the disk types, USB connection, etc.
Generally, EaseUS Disk Copy is useful software to clone RAID arrays. Besides, this RAID clone software also supports moving OS to a new SSD, cloning a larger hard drive to a smaller one, clone SATA TO NVMe SSD, and so on.
